Description and Specification for Lab Tenders
Motorised Governor Apparatus.
The unit consists of a base upon which the bearing holders and
driving motor are bearing can be fitted in a holders to end conditions
for test shafts, viz. Both end fixed and one end free, one end fixed. A
Variac provided control of driving motor. The unit demonstrates the
phenomenon of whirling of shafts with single rotor. As the test is
destructive, after the test cannot be used, hence the unit only
demonstrates the principle.
However, results obtained are closer to theory, as compared to
those with bare shafts. Also, It can be demonstrated that, after passing
whirling speed, shaft again starts running true.
