Title: Starting circuit for group of motors
Inventor: NISHIJIMA HIDEO
IPC: H02P1/58
Filed: 1979-05-21
Abstract: PURPOSE:To avoid concentration of current requirement by a method wherein the status showing a motor has reached a sufficient rotational speed is detected through a variation of a control voltage at a speed control circuit and afterward another motor is started. CONSTITUTION:A drum motor 1 is driven by a motor driving circuit 2, and a regulated rotational speed is attained through a feedback of a control circuit 3 which performes a control action by generating a control signal through sensing a speed by an oscilator, etc. of which frequency varies in accordance with the rotational speed of the drum and a switching circuit 4. A capstan motor 5 is operated in the same way. By applying a motor starting signal on a terminal 10 the switching circuit 4 chaged a mode to a motor-start side, and rotation of a drum motor is initiated. At this stage an output voltage of the control circuit 3 varies to be inversely proportional to a rotational speed of the drum. The control voltage is detected by a detecting circuit 9 and the capstan motor is started.
