Title:
MOTOR CONTROLLER
Document Type and Number:
Japanese Patent JP3886323
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a motor controller which can improve reduction in size and reliability of an electromagnetic switch of the power supply to drive a plurality of motors and thereby realizes reduction in size at a lot cost.
SOLUTION: This motor controller comprises an electromagnetic switch 16 connected in parallel with a rush current suppression resistor 15, a main circuit voltage comparison circuit 17 for detecting that the main circuit voltage is higher than the predetermined voltage, an electromagnetic switch drive circuit 18 for switching the contacts of the electromagnetic switch 16, and a wired OR circuit for inputting a servo ON signal from each drive unit to drive a plurality of motors. This wired OR circuit 19 closes, upon receiving a servo ON signal from at least one drive unit, the contacts of the electromagnetic switch 16 with the electromagnetic switch drive circuit 18.
