A safety device for video cassette recorder.

摘要

Motor control apparatus comprised of a drive circuit (3) for supplying drive current to a motor (2), an overload detector (4) coupled to the motor (2) for detecting the magnitude of the motor current to produce an output signal if that current exceeds a predetermined threshold level caused by motor overload, and a control circuit (5) coupled to the drive circuit (3) and responsive to the output signal for controlling the drive current supplied to the motor (2), thereby controlling motor operation.
