Title:
BRAKE DRIVING DEVICE FOR DRIVING MECHANICAL BRAKE DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/095465
Kind Code:
A1
Abstract:
This brake driving device comprises: a positive-side switch for opening/closing a positive-side electrical path between a power source and a mechanical brake device; a negative-side switch for opening/closing a negative-side electrical path between the power source and the mechanical brake device; and a switch control unit for outputting an OFF signal to the positive-side switch and the negative-side switch when braking is to be activated, outputting an ON signal to the positive-side switch and the negative-side switch at the start of brake release when braking is to be released, and while subsequently keeping the braking released, alternately switching between output of a PWM-controlled ON/OFF signal to the positive-side switch and output of the PWM-controlled ON/OFF signal to the negative-side switch at predetermined time intervals.
