Title:
CONTROL DEVICE FOR GEAR MOTOR
Document Type and Number:
Japanese Patent JP2017060239
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a control device for a gear motor mounted in a washing machine or the like by which an operation of stopping an output shaft rotational angle of a gear motor containing a contact for detecting the rotational position at a predetermined angle can be surely performed even under a high-humidity environment with a low-cost configuration.SOLUTION: A control device for a gear motor having a voltage detection circuit 23 for detecting the state of a contact 11 operated by a cam 10 which is connected to an output shaft 2 and rotates drives a motor 4 with an insulation type relay 25. A common terminal 6a of a contact 11 and the motor 4 is connected to a common line of the power source of the motor 4 and the power source of a microcomputer 20. A signal is obtained from the voltage detection circuit 23 connected to a terminal 6b as another terminal of the contact 11 to detect the state of the contact 11. Accordingly, the control device for the gear motor that operates surely even under a high-humidity environment with an inexpensive configuration can be realized.SELECTED DRAWING: Figure 4
