Abstract

PURPOSE:To stop a motor in a short time, by driving the motor in the direction of reverse rotation at the time of stopping the motor during forward rotation, and by interrupting reverse rotation signal when the rotational frequency comes to a constant value. CONSTITUTION:When a motor 4 is stopped, then reverse rotation signal is applied to a motor driving circuit 3 through a reverse rotation signal wire 5 from a microcomputer 1. The motor 4 is reverse-rotation-driven, and the input of the rotating speed signal of the motor 4 to the micro-computer 1 from a tachometer generator 5 and a waveform shaping circuit 7 is provided. This rotating speed is detected as a rotational period, and when this period comes to a constant value, then the output of the reverse rotation signal is interrupted by the micro-computer 1. At the same time, motor-rotational order is also interrupted.
