Abstract

A motor with a brake in which, after an initial stage, a voltage applied to the brake is reduced to thereby restrain heat generation in the brake. In the motor with a brake, after signal drive, a voltage of a drive signal supplied to an electromagnetic drive portion of the brake is reduced, whereby heat generation in the brake during motor rotation is restrained, which makes it possible to increase a load to be applied to the motor.

Description

technical field

[0001] The present invention relates to a motor with a brake, in particular to a new type of improvement. When the motor driving power is turned on and the initial excitation is performed for releasing the brake, the usual voltage is applied, and after the initial excitation, a lower voltage is passed. Excitation, thereby suppressing the coil heating of the electromagnetic drive part of the brake. Background technique

[0002] In the motor with brake used in the past, when the motor is turned on, its electromagnetic drive part starts, and the brake is kept released through electromagnetic action. When the motor is turned off, the brake is closed by the action of the spring, so that the rotation of the rotor is stopped. state (for example, Patent Document 1).
