Ball and Beam Apparatus (Product Code: SLE/ETC/03) is an unstable-system control trainer used to teach active feedback control of a naturally unstable double integrator in control engineering laboratories. A steel ball rolls on two parallel tensioned wires carried by a centre-pivoted beam, while a servo motor tilts the beam and sensors report beam angle and ball position. The apparatus comes from Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, and is made at its own factory in Ambala, India.

Key Details

What Is the Ball and Beam Apparatus Used For?

The basic control problem is to vary the beam angle so the ball stays at, or moves to, a chosen position. Left alone, the ball simply rolls to one end — which is exactly why the apparatus is valuable: students must design a controller that actively stabilises the system rather than merely speeding up one that is already stable.

A common teaching sequence starts with an inner loop on beam angle through the servo motor, followed by an outer ball-position loop using phase-advance (lead) compensation. The comparison with launch-vehicle stability makes the theory memorable for aerospace, mechatronics and electrical students, and gives engineering lab equipment collections a very visible demonstration of instability.

OEM Manufacturer

ScienceLab is the brand under which Jain Scientific Equipments Private Limited sells its own laboratory equipment, and the company is the OEM for the Ball and Beam Apparatus. The unit is fabricated and assembled at its licensed factory in Saha, Ambala, Haryana, India. Because buyers deal with the manufacturer directly, questions about a replacement ball, wires or other spares can simply be put to us. Learn more on the company profile.

Frequently Asked Questions

Why is the Ball and Beam Apparatus unstable?
The Ball and Beam Apparatus is a double integrator: tilting the beam makes the ball accelerate, and its position keeps changing unless the angle is corrected. This makes it naturally unstable, so it needs active feedback control using phase-advance methods.

What sensors are fitted to the Ball and Beam Apparatus?
The Ball and Beam Apparatus has sensors that measure the beam angle and the ball position. A servo motor controls the beam angle, giving students both the measurements and the actuator needed to close a position-control loop.

What does the ball roll on in the Ball and Beam Apparatus?
In the Ball and Beam Apparatus, a steel ball rolls freely on two parallel tensioned wires. The wires sit on a beam that pivots at its centre, so changing the beam angle moves the ball along the wires.

What real systems does the Ball and Beam Apparatus represent?
The Ball and Beam Apparatus represents the control problems of unstable systems, for example a rocket or missile during launch, which needs active control to stop it going unstable and toppling over.

Who manufactures the Ball and Beam Apparatus?
Jain Scientific Equipments Pvt Ltd (ScienceLab) manufactures the Ball and Beam Apparatus as the OEM at its own licensed factory in Saha, Ambala, Haryana, India. Buying from the maker means a replacement ball or wire can be requested from the same source.

Can the Ball and Beam Apparatus be ordered for several lab benches?

Engine Speed Control Apparatus (Product Code: SLE/ETC/04) is a speed-regulation trainer used to show the problems of controlling rotating machines, especially non-linear control systems, in engineering laboratories. It uses a scale-model engine driven by compressed air for safety, a motorised valve that sets engine speed, and a d.c. generator that loads the engine output. Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, produces it at its own factory in Ambala, India.

Key Details

What Is the Engine Speed Control Apparatus Used For?

The basic purpose is to adjust the motorised valve so the engine holds a set speed while the d.c. generator loads it. Valves and air-driven engines seldom respond in a straight line, so students meet non-linear behaviour directly and learn why a controller tuned at one operating point may struggle at another.

Advanced sessions use dither signals to compensate for non-linearity, compare single-loop control with multiple-loop and minor-loop structures, build a model from step-response data and design P+I controllers with root-locus methods. Running the model engine on compressed air rather than fuel keeps the exercise safe for teaching, which makes it a practical addition to engineering lab equipment for mechanical, automotive and control courses.

OEM Manufacturer

Jain Scientific Equipments Private Limited — known to customers as ScienceLab — is the OEM for the Engine Speed Control Apparatus and builds it at its own licensed factory at Saha, Ambala, Haryana, India. Engineering colleges, training centres, dealers and importers order directly from the company that makes it, so quotations, repeat orders and spare-part questions are all handled at source.

Coupled Drives Apparatus (Product Code: SLE/ETC/05) is a multi-variable drive trainer used to study the control of speed and tension in belt-coupled drives in control and electrical engineering laboratories. Two electric motors are linked by a continuous flexible belt that also passes over a swinging arm, where a jockey wheel measures belt speed and tension. It is built by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Key Details

What Is the Coupled Drives Apparatus Used For?

In a coupled drive, changing either motor's torque affects belt speed and belt tension at the same time, so the two outputs interact. Students first control speed and tension separately, then attempt simultaneous control of velocity and tension, and discover why a multi-variable system needs a coordinated strategy rather than two independent loops.

Adjusting the spring tension at the swinging arm changes the plant, giving instructors a simple way to test how robust a controller is. The same problems occur in magnetic tape drives, textile machines and paper mills, which helps mechanical and electrical students connect theory to industry — a useful addition to any technical educational equipment list.

OEM Manufacturer

The Coupled Drives Apparatus is an OEM product of Jain Scientific Equipments Private Limited, which trades as ScienceLab. It is manufactured at the company's own licensed factory at Saha, Ambala, Haryana, India and dispatched from there to universities, colleges, dealers and importers. If you later need matching units or a replacement part such as a belt, ask us directly — you will be speaking with the maker. The ScienceLab company profile gives further background.
