WIPO Patent Application WO/2011/162328
Kind Code:
A1
Abstract:
Disclosed is a motor braking apparatus provided with: a voltage detection unit (15) for detecting inter-terminal voltages between terminals (2a) of a motor (2); a frequency/voltage conversion unit (16) for converting the frequencies of the voltages between the terminals into voltage values, and outputting the voltage values; a voltage comparison unit (17) for comparing the voltage values outputted by the frequency/voltage conversion unit with a prescribed threshold value; and a braking unit (20) for applying brakes onto the motor on the basis of the result of the comparison by the voltage comparison unit.
