How does elevator brakes work?

When the elevator is at a standstill, no current flows through the coils of the traction motor and the electromagnetic elevator brake. At this time, due to the lack of attraction between the electromagnet cores and the brake pads under the pressure of the brake spring, the brake wheels are held together. When the traction motor is energized and rotated, the coil in the brake electromagnet is simultaneously supplied with current, and the electromagnet core is quickly magnetized and pulled in, driving the brake arm to make the brake spring acted on, restraining the The moving pad is opened and completely separated from the braking wheel, and the elevator can run; when the elevator car reaches the required stop, the traction motor is de-energized, and the coil in the braking electromagnet is also de-energized at the same time, and the electromagnet core is de-energized. The magnetic force of the elevator disappears quickly, and the iron core is reset by the brake arm under the action of the brake spring, so that the brake pad hugs the brake wheel again, and the elevator stops working.
