Title: Brake controller for motor with electromagnetic brake
Inventor: YAMANE MITSURU
IPC: H02P3/04
Filed: 1997-03-07
Abstract: PROBLEM TO BE SOLVED: To suppress generation of heat by applying a total voltage to an electromagnetic brake only during the initial operation thereof and then diving the applying voltage thereby reducing power consumption of the brake. SOLUTION: A servo motor 1 comprises a motor 1a and an electromagnetic brake 1b wherein the motor 1a is subjected to drive control through a driver 2. A brake control circuit 4 is connected between a controller 3 and the electromagnetic brake 1b(22) of the servo motor 1. When a voltage 21 is outputted from the controller 3, a switch 24 is closed through a control section 25 and the control circuit 4 applies a total voltage to the electromagnetic brake 22. After the electromagnetic brake 22 is attracted, the switch 24 is opened and a resistor 23 is conducted. Since the voltage being applied to the electromagnetic brake 22 is divided between the resistor 23 and the electromagnetic brake 22 after it is attracted, power consumption is reduced and temperature rise due to heating is suppressed.
