Abstract
Provided is a release device for a non-excitation type electromagnetic brake that receives power supply from a battery via a brake control device to release a braking state, including: a bypass circuit that connects the battery and the non-excitation type electromagnetic brake without intermediary of the brake control device; a first switch that turns on and off energization to the bypass circuit; and a first step-down circuit provided on the bypass circuit and that reduces a voltage supplied to the non-excitation type electromagnetic brake. The first step-down circuit includes a resistor and a second switch connected in parallel; and a timer circuit that controls on and off of the second switch.
