Abstract
PURPOSE: To eliminate a relay for a loading motor by enabling the energization of loading and traveling motor only via a relay connected in series with a battery.
CONSTITUTION: The output of a battery is supplied through a fuse 7 and the contact 10 of a relay 6 to a travelling motor 2, a traveling chopper circuit 4, a loading motor 3, and a loading chopper 5. When a commutation is failed in the chopper 5, a commutation failure protecting circuit 9 operates to conduct a trasistor 8. Thus, a current flows through the coil 11 of the relay 6 to open the contact 10, thereby eliminating the energization of the motor 3. In this manner, the loading motor can be stopped in case of the commutation failre without the relay for the loading purpose motor.
