PURPOSE:To stabilize an accelerated steady state in a short time when a motor is started by setting the measurement of the speed of the motor newly started and the calculation of a duty by twice or more of the motor already rotated at the normal speed. CONSTITUTION:A data selector DS for selecting one signal of an encoder for outputting in response to the rotating speeds of a plurality of motors, a plurality of drivers ORIV for driving motors, a counter CNTR for detecting the rotating speed of the motor by the signal from the encoder, and a controller CTRL for controlling the DRIV by the rotating speeds of the motors detected by the CNTR are provided. The measurement of the speed of the newly rotated and the calculation of a duty are performed at twice or more of the motor already rotated at the normal speed until the motor arrives at the normal speed, thereby performing the desired purpose. |
