A stopping noise reduction circuit for a start motor comprises a battery generating a power supply to drive the start motor, a key switch for controlling an on/off of the power supply, a solenoid having a permanent magnet, P and H coils, and a movement contact to drive the start motor, and further comprises a B1 terminal grounded inside the solenoid, an M1 terminal connected to an M terminal of the start motor, and a resistor coupled with the B1 or M1 terminal. In the stopping noise reduction circuit, upon an off condition of the key switch, the movement contact of the solenoid is connected to the B1 and M1 terminals such that more induced current than an induced current flowing into the P and H coils, in a current induced by a rotator of the start motor, flows to ground via the resistor within a short flow time.
A stopping noise reduction circuit for a start motor comprising a battery for providing power to drive the start motor, a key switch for controlling an on/off state of the power supply from the battery, and a solenoid having a permanent magnet, P and H coils, and a movement contact to drive the start motor, the circuit comprising:
A stopping noise reduction circuit for a starter motor comprising a battery for providing power to drive the starter motor, a key switch for alternately connecting the battery to and disconnecting the battery from the starter motor, and a solenoid having a permanent magnet, P and H coils, and a movement contact to drive the starter motor, the stopping noise reduction circuit comprising:
