Motorised Gyroscope Apparatus Manufacturer,Supplier and Exporter in India
Product Code : EL-TOMLE-10008
Jlab Export is a leading Motorised Gyroscope Apparatus Manufacturer,and suppliers in India
Weights placed on a platform apply a known couple to the spinning rotor of this apparatus, and the rotor responds by precessing. The 250 mm rotor runs in bearings on a variable speed motor, set with a dimmerstat. It is free to turn about its spin, precession and couple axes, and a counterweight balances the motor.

Checking the Gyroscopic Couple
A rotor with moment of inertia I, spinning at ω and precessing at ωp, needs a gyroscopic couple C = I ω ωp. The spin, precession and couple axes are at right angles to one another. A weight on the platform applies a couple equal to the weight times its distance from the rotor centre, and the test compares that couple with I ω ωp.
Experiments for Students and Teachers
Students verify the gyroscopic couple at several spin speeds and loads. For each run they read the spin speed with a Stroboscope, which needs no contact with the rotor. They time a measured angle of precession with a Digital Stop Watch. A plot of applied couple against ω ωp gives a straight line whose slope is I. Teachers can reverse the spin, or move the weight to the other side, to show that the precession changes direction.
Frequently Asked Questions
Why do the measured and calculated couples differ?
Friction in the rotor bearings and at the frame pivots takes up part of the applied couple. The spin speed can also drift during a run, and timing a short angle of precession by hand adds error. A steady speed and a longer timed angle bring the two closer.
Which weights come with the apparatus?
Weights of 0.2 kg, 0.5 kg and 1 kg are supplied for loading the platform. Using each weight at more than one spin speed gives a set of readings for comparing the applied couple with I ω ωp.
How are the spin and precession speeds measured?
Time the frame through a known angle of precession with the stopwatch and divide the angle in radians by the time. Spin speed is read with a tachometer, which can be supplied as an extra item, or with a stroboscope.
What supply and space does it need?
A 220 V stabilised AC supply with an earthing connection, and a bench area of 0.5 x 0.5 m at working height. Keep hands and loose clothing clear of the rotor while it runs.
How does it differ from a hand-spun gyroscope?
Here the motor holds the rotor at a steady speed set on the dimmerstat, so a reading can be repeated at the same speed. A hand-spun rotor slows a little through each run, so its speed has to be read again for every reading.
