Document Type and Number:
Japanese Patent JP2013527100
Kind Code:
A
Abstract:
A braking device for an elevator is disclosed. The device may include a motor, a braking system, a first switch, and a second switch. The motor may be capable of generating a counter-electromotive force. The braking system may move to a disengaged position upon being energized and may move to an engaged position upon being de-energized. The first and second switches may have an open state. In the open state, the switches electrically couple the motor to the braking system so that the counter-electromotive force of the motor may energize the braking system.
