Abstract:

A tachometer-generator drive unit is described which is capable of providing a range of discrete speeds from 500 revmin to 6000 revmin. Use is made of an existing Velodyne and its associated control circuit to which an additional phase sensitive error signal is fed. The long term accuracy approaches that of the crystal oscillator which is used as a reference source. The limits within which the instantaneous velocity may vary have not been determined. Author
