Motorised Gyroscope Apparatus
Product Code : LSK-TOMLE-10618
Motorised Gyroscope Apparatus (SKU LSK-TOMLE-10618) demonstrates the gyroscopic couple: a 250 mm motor-driven rotor, free to turn about three axes, precesses when torque is applied through weights. Mechanical engineering students use it to verify the relation between spin speed, precession speed and applied couple. The apparatus is produced by Science Lab Supplies at its manufacturing unit in Saha, Ambala, Haryana, India, which sells it directly to engineering colleges, polytechnics, tender contractors and distributors.
Specifications
Rotor, drive, weights and site needs of the gyroscope are tabulated one per row below. In short, a 250 mm rotor in bearings, free about three axes, is spun by a dimmerstat-controlled motor balanced by a counterweight, while 0.2, 0.5 and 1 kg weights on a platform apply the couple.

Applications and Experiments for the Motorised Gyroscope Apparatus
Students spin the rotor at a set speed, load the weight platform and time the resulting precession. Comparing the measured couple with the product of moment of inertia, spin speed and precession speed verifies the gyroscopic law, a core Theory of Machines practical.
- B.Tech/B.E. mechanical, Theory of Machines: verifying the gyroscopic couple equation, building on rotor inertia measured with an Inertia Table.
- Diploma mechanical engineering: identifying spin, precession and couple axes.
- Applied examples: gyroscopic effects on ships, aircraft and vehicles turning at speed.
- Physics groundwork: finding moment of inertia by oscillation on the Bifilar Pendulum before the gyroscope practical.
Keep fingers and loose clothing away from the spinning rotor and change weights only after the speed has been reduced.
Standard Scope of Supply

Frequently Asked Questions
Is a tachometer supplied with the Motorised Gyroscope Apparatus?
No. The tachometer for measuring rotor speed is listed as a service requirement and can be supplied at extra cost on the same quotation.
What does the apparatus need on site?
It needs a 220 V stabilised AC supply with an earthing connection and a bench area of about 0.5 x 0.5 m at working height, with space nearby to set down the weights.
Does Science Lab Supplies make this gyroscope itself?
Yes. The gyroscope is built in the Science Lab Supplies factory at Saha, Ambala, India, and quotations, technical queries and dispatch are all handled by the manufacturer.
How is the gyroscopic couple applied?
Weights of 0.2, 0.5 or 1 kg are placed on the weight platform. Their moment about the pivot is the applied couple that makes the spinning rotor precess.
