トドライブモータを起動することを特徴とす゛るダイレ
クトドライブモータの起動回路。A power transistor that turns on and off an appropriate drive voltage applied to a motor control section of a direct drive motor, a base control circuit that applies a control voltage to the base of the power transistor in synchronization with a motor enable signal, and a base circuit of the power transistor. a time constant circuit that is inserted into the power transistor and raises and lowers the base potential of the power transistor at a predetermined time constant; and a low voltage application circuit that applies a voltage lower than the appropriate driving voltage to the motor control section when the power is turned on. , At the same time as the power is turned on, the low voltage is applied to the motor control section, and in this state, the motor enable signal is turned on, and the appropriate driving voltage is applied to the motor control section via the power transistor to drive the direct drive. A direct drive motor starting circuit that starts the motor.
