What Is the LPI Hybrid Engine Fault Trainer Used For?

Hybrid systems are easiest to teach when students can watch several control units cooperate in real time. On this trainer, the instructor walks the class through each operating mode — hybrid start, idle or creep support, acceleration assist and energy recovery on braking — while the display panel shows engine start and status. Because the HCU, engine ECU, TCM, battery management ECU, motor control unit and LDC share a CAN network, students learn how a fault in one unit can appear as a symptom in another, which is central to modern hybrid diagnosis.

Diagnostic exercises use the education check terminal and toggle switches on the front panel: trainees check sensors, look for short circuits and confirm output power with diagnosis equipment, and the optional oscilloscope captures signals from the CAN-linked units. The unit is a substantial installation for engineering colleges looking for advanced lab equipment for technical institutes, so plan a dedicated bay with suitable floor strength and delivery access.

Ball and Hoop Apparatus (Product Code: SLE/ETC/06) is an electromechanical servo trainer used to demonstrate position and velocity control, and to model liquid-slop dynamics, in control engineering laboratories. A steel ball rolls inside a hoop that is free to rotate under servomotor control, while transducers output both the hoop position and the ball position. The trainer is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Key Details

What Is the Ball and Hoop Apparatus Used For?

At its simplest, students close a servo loop on hoop position or speed and study the response. The richer exercises come from the ball: once the hoop is under angular position control, the ball swings like a cylindrical pendulum, adding an oscillating motion that the controller has to take into account.

That pendulum-like motion is a laboratory model of liquid slopping about in a moving container — the same issue designers face with aircraft and missile fuel storage, fuel tankers and industrial pumping systems. Students can try to move the hoop briskly while keeping the ball's swing small, a practical introduction to oscillation control for mechatronics and control courses that rely on engineering educational equipment.

OEM Manufacturer

Jain Scientific Equipments Private Limited, trading as ScienceLab, is the OEM that makes the Ball and Hoop Apparatus at its own licensed factory in Saha, Ambala, Haryana, India. Institutions and distributors buy it straight from the factory, and follow-up needs such as spare parts or additional units can be raised with the same team.

The company is registered as an MSME under Udyam number UDYAM-HR-01-0003714 and holds Importer-Exporter Code AAECJ8618A from the DGFT for its export shipments. Read more on the ScienceLab profile.

• Servo Trainer — d.c. servo speed and position control with a clutched reduction gearbox
• Coupled Drives Apparatus — interacting speed and tension control of two motors
• Digital Interface — computer input/output for recording hoop and ball signals

Explore the Control & Process Engineering Trainers category for more.

Frequently Asked Questions

What does the Ball and Hoop Apparatus demonstrate?
The Ball and Hoop Apparatus demonstrates electromechanical servo systems for position and velocity control. Because the ball behaves like a cylindrical pendulum inside the rotating hoop, it also models liquid-slop dynamics for more advanced studies.

What signals does the Ball and Hoop Apparatus provide?
Transducers on the Ball and Hoop Apparatus give outputs of the hoop position and the ball position. Students use them to close the servo loop on the hoop and to observe or control the ball's pendulum-like motion.

What is liquid slop, and why model it with the Ball and Hoop Apparatus?
Liquid slop is the sloshing of liquid in a moving container. The Ball and Hoop Apparatus models it with a ball swinging inside a hoop, which is relevant to aircraft missile fuel storage, fuel tankers and industrial pumping systems.

What drives the hoop of the Ball and Hoop Apparatus?
The hoop of the Ball and Hoop Apparatus is free to rotate but is controlled by a servomotor. Students command the servomotor to set the hoop angle or speed and then watch how the steel ball responds.

Who manufactures the Ball and Hoop Apparatus?
The Ball and Hoop Apparatus is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, at its own licensed factory in Saha, Ambala, Haryana, India. Dealers and importers order it factory-direct, with export handled under the company's own IEC.

Excavator Electric Circuit Training Simulator (Product Code: SLE/ATE/21) is an open-layout electrical trainer used to teach troubleshooting and inspection of a hydraulic excavator's electric circuit in heavy-machinery and construction-equipment courses. It uses the electronic systems of a Hyundai heavy machinery excavator 555-7K, with parts that are hidden on a real machine laid open so trainees can see their location and operating state. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Specifications

What Is the Excavator Electrical Trainer Used For?

Excavator operators and service technicians meet electrical faults that are hard to trace on a working machine, where wiring runs behind panels and under the cab. On this simulator, trainees work the operating lever, hydraulic lever, horn and lights and watch the instrument panel respond, then measure the input and output at each component to learn what a healthy circuit looks like. With those normal values recorded, instructors can walk them through a logical fault-finding sequence: battery and connector first, then relays, starter motor and switches.

The open layout also helps with component identification for learners who will later work on real machines at construction and mining sites. In a TVET heavy-equipment workshop, pairing it with an operator simulator lets students learn both how the machine is driven and how its electrical system supports those controls. Disconnect the battery connector before changing any wiring on the panel.

Supplier

Jain Scientific Equipments Private Limited, trading as ScienceLab from Ambala, Haryana, India, supplies this excavator circuit simulator to ITIs, polytechnics, heavy-equipment training centres, dealers and importers in India and international markets. Because the trainer is based on the electronic systems of a Hyundai excavator, the company sources it and handles the quotation and delivery for the buyer.

Servo Trainer (Product Code: SLE/ETC/07) is a d.c. servo control trainer used to teach position and speed control with typical industrial techniques in electrical and control engineering laboratories. A d.c. servomotor, d.c. generator and flywheel share one shaft, with an electric clutch that engages a 30:1 reduction gearbox for position work and a panel-mounted digital meter that shows speed. Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, makes it at its own factory in Ambala, India.

Specifications

What Is the Servo Trainer Used For?

Students usually begin with speed control, driving the servomotor with an analogue signal and reading speed from the optical sensor, then load the shaft with the d.c. generator to see how well a controller rejects disturbances. Engaging the clutch switches to position control through the reduction gearbox, with the manual control providing the position setpoint.

Swapping the interchangeable inertia discs changes the plant, so learners can observe the effect on response and stability. For advanced work, the included block circuits introduce adjustable deadzone, anti-deadzone, hysteresis and saturation — the non-linearities that make real servos misbehave — so classes can study and compensate for them. This breadth makes it a versatile piece of electronics lab equipment for polytechnics and engineering colleges.

OEM Manufacturer

ScienceLab is the trading name of Jain Scientific Equipments Private Limited, the OEM responsible for the Servo Trainer. The company manufactures it at its own licensed factory in Saha, Ambala, Haryana, India, so buyers receive quotations and technical answers from the source rather than from a reseller. Colleges adding more benches later can order matching units directly — ask us for current details. See the company profile for more.

Related Control & Process Engineering Trainers

Other trainers that share the Servo Trainer's focus on motion control:

• Coupled Drives Apparatus — speed and tension control with two belt-coupled motors
• Engine Speed Control Apparatus — speed regulation of a generator-loaded model engine
• Ball and Beam Apparatus — servo-driven stabilisation of an unstable system
• Controller — analogue PID, phase-lead and summing blocks for servo loops

See the complete Control & Process Engineering Trainers category.

Frequently Asked Questions

The Servo Trainer uses analogue control signals of 0 to ±10 V, which vary the servomotor shaft speed in either direction, so students can drive it from an analogue controller or a suitable interface.

How is speed measured on the Servo Trainer?
An optical sensor on the Servo Trainer measures shaft speed and shows it on a panel-mounted digital meter, so students can read the speed directly while they test their control settings.

What is the gearbox ratio on the Servo Trainer?
The Servo Trainer has a 30:1 reduction gearbox. An electric clutch connects or disconnects the shaft from the gearbox, letting users switch between speed-control studies and position-control studies on the same unit.

Can the inertia of the Servo Trainer be changed?
Yes. The Servo Trainer comes with two extra interchangeable inertia discs (flywheels) for adjusting shaft inertia, so students can compare how a controller performs with lighter and heavier rotating loads.

Which non-linear effects can be added on the Servo Trainer?

Wheel Loaders Electric Circuit Training Simulator (Product Code: SLE/ATE/22) is an open-frame electrical trainer used to teach troubleshooting and inspection of a heavy-machinery wheel loader's electric circuit in vocational and engineering workshops. It runs on a DC 24 V battery with an ECU, relays, starter motor, levers and built-in digital meters, so trainees can measure input and output data at each component. It comes from Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM manufacturer, and is made at its own factory in Ambala, India.

Specifications

What Is the Wheel Loader Electrical Trainer Used For?

Wheel loaders run on 24 V electrical systems with an ECU managing many functions, and trainees need to be comfortable with both before they work on machines in quarries, ports or construction sites. On this simulator, students operate the levers, lights and horn and crank the starter motor, reading the built-in meters to build a picture of normal circuit behaviour. Instructors then use that baseline to teach inspection routines and troubleshooting theory: checking the battery and connector, testing relays, and confirming the signals reaching and leaving the ECU.

Because the components are opened out where they can be seen, learners spend less time searching for parts and more time reasoning through a fault. The unit fits naturally into engineering educational equipment for heavy-machinery maintenance courses. Remove the battery connector before altering any wiring, and treat the 24 V battery with the same care as on a real machine.

OEM Manufacturer

ScienceLab is the trading name of Jain Scientific Equipments Private Limited, the OEM (original equipment manufacturer) of the Wheel Loaders Electric Circuit Training Simulator.

Digital Interface (Product Code: SLE/ETC/09) is a computer interface unit used to connect laboratory control apparatus to a PC for signal monitoring and computer-based control in engineering laboratories. It converts analogue signals from equipment into digital form for the computer, and turns the computer's digital outputs back into analogue control signals, handling up to eight inputs and four outputs. It is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Digital Interface Used For?

Many control courses now implement controllers in software. The Digital Interface makes that possible on physical hardware: sensor signals from an apparatus are digitised for the computer, the control algorithm runs on the PC, and the resulting outputs are converted back into analogue signals that drive pumps, heaters or motors.

With eight inputs, several measurements — for example two tank levels plus a flow reading — can be monitored at once, while four outputs cover experiments with more than one actuator. Choosing the Digital Interface instead of the Controller suits labs that already have their own analogue controllers, or that want benches centred purely on computer control, and it slots easily into existing engineering lab equipment in India and abroad.

OEM Manufacturer

Jain Scientific Equipments Private Limited, the company behind the ScienceLab brand, is the OEM of the Digital Interface and produces it at its own licensed factory in Saha, Ambala, Haryana, India. Because the maker supplies it directly, institutions can ask the same team about matching it to existing apparatus, adding units for more benches or obtaining replacement parts.

Overcurrent And Earth Fault Relay (Product Code: SLE/EPS/01) is a programmable protection-relay module used to teach how overcurrent and earth-fault protection is set, tested and verified in power system and electrical engineering laboratories. It is based on the Micom P122 industrial relay and provides three independent three-phase overcurrent and earth-fault stages, the first selectable from 12 IDMT curves. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Specifications

What Is the Overcurrent and Earth Fault Relay Used For?

Protection relays decide when a circuit breaker must trip, and setting them correctly is a core skill for power engineers. In the lab, the lecturer or students build a fault circuit on the Protection and Relay Test Set, program the relay module for the test using its keypad and display (or from a computer running the relay support software), and then apply the fault. Measuring how quickly the relay operates at different fault currents lets students plot its real characteristic and compare it with the selected IDMT curve.

Because the first stage offers 12 IDMT curves and the remaining stages have a direct time characteristic, one relay can show how the choice of curve changes tripping times and how separate stages are graded against each other. Further exercises cover restricted earth fault, thermal overload, negative-phase-sequence protection and broken conductor detection, while the stored fault and disturbance records let students review each event after the test.

What to Specify When Ordering

• Whether you already have a Protection and Relay Test Set or need a test arrangement discussed with us.
• Whether a computer and the relay support software should be arranged for programming.
• Other protection relays for the same lab, such as differential, distance or directional types.
• Number of relay modules for your student groups.
