Abstract

PURPOSE: To apply a strong braking force to a motor, by supplying a signal to rotate the motor in reverse.
CONSTITUTION: The terminal voltage V1 of one stator coil L1 is supplied to an amplifier 13 for shaping the wave from of the voltage. A sampling signal P1, which varies between a positive and negative levels, is supplied from the amplifier 13 to a sampling gate circuit 14. The terminal voltage V2 of another stator coil L2 is another wave form shaping amplifier 17. The output pulse signal P2 of the amplifier 17 is supplied as a sampling pulse signal P3 to the sampling gate circuit 14 through a differentiation circuit 18. The sampled output voltage V0 of a capacitor 15 has such polarity as to rotate the motor in reverse. The sampled output voltage V0 is applied as a stop signal Ss to a motor driving circuit through a stop switch 20.
