Servo Trainer
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
| Parameter | Detail |
|---|---|
| Drive train | d.c. servomotor, d.c. generator and flywheel mounted on a common shaft |
| Control signal | Analogue, 0 to ±10 V, varying servomotor shaft speed in either direction |
| Speed measurement | Optical sensor, with speed shown on a panel-mounted digital meter |
| Loading | d.c. generator loads the servomotor statically or dynamically |
| Position control | Electric clutch connects or disconnects the shaft to a 30:1 reduction gearbox |
| Position setpoint | Manual control |
| Inertia adjustment | Two extra interchangeable inertia discs (flywheels) supplied |
| Non-linear effect circuits | Block-type circuits adding fully adjustable deadzone (deadband), anti-deadzone, hysteresis and saturation |

| Manufacturer | Jain Scientific Equipments Pvt Ltd (ScienceLab) — OEM |
| Country of origin | India (made in Ambala, Haryana) |
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.

Frequently Asked Questions
What control signal does the Servo Trainer use?
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?
The Servo Trainer includes block-type circuits that add fully adjustable deadzone (deadband), anti-deadzone, hysteresis and saturation effects, allowing advanced experiments on how non-linearities affect servo position and speed control.
Who manufactures the Servo Trainer?
Jain Scientific Equipments Pvt Ltd (ScienceLab) manufactures the Servo Trainer as the OEM at its own licensed factory in Saha, Ambala, Haryana, India. Extra inertia discs or other spares can be requested from the manufacturer; ask us about availability.
Is a calibration certificate available for the Servo Trainer's speed meter?
Calibration-certificate availability for the Servo Trainer's panel-mounted digital speed meter should be discussed with us before ordering. Include the requirement in your enquiry through the contact page so it can be confirmed in writing.
