Claims

[Scope of utility model registration request]

A motor, a motor servo circuit that supplies motor current to the motor, controls the rotation, and outputs a status signal indicating the state when the rotation speed reaches a preset regular rotation speed; a control means for outputting a start signal to cause the motor to stop, and the start signal from the control means and the state signal from the motor sagobo circuit can be input, and when the state signal is not input after a certain period of time after the start signal is input; A motor servo device comprising: a motor stop circuit that outputs a control signal to the control means and interrupts generation of the start signal.
