Title:
MOTOR DRIVE CIRCUIT
Document Type and Number:
Japanese Patent JP3406834
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a motor drive circuit in which the number of required realys is reduced, which is made lightweight and whose low costs are realized.
SOLUTION: The common contact 5a of a power supply circuit relay 2a is connected to the common contact 15a of a motor circuit relay 12a. The common contact 5b of a power supply circuit relay 2b is connected to the common contact 15b of a motor circuit relay 12b. Then, respective contacts 6a, 6b of the power supply circuit relays 2a, 2b and those 16a, 16b of the motor circuit relays 12a, 12b are changed over individually by the relay changeover signal of an ECU. When the power supply circuit relays 2a, 2b are changed over alternatively, an electrifying direction to respective motor circuits 21 to 24 is changed over.
