摘要：A spin motor rotation detector for a split phase or two phase motor drive for a gyroscope applies the spin motor supply voltage and the phase winding voltage to a semi-conductor, e.g., the supply voltage is applied as a reference voltage to the gate on a semi-conductor such as a FET used as a demodulator while the phased motor winding provides the source or (signal) input voltage to the FET demodulator. The phase modulation of the phase winding voltage resulting from hunting during operation of the motor is reflected in the output from the demodulator, and the output is applied to a logic level DC output to indicate satisfactory or unsatisfactory speed of operation of the split phase motor during changes in physical orientation of the gyroscope.
