Abstract
An apparatus for monitoring a motor brake is provided. The apparatus includes a monitoring portion that is configured to measure state information of the brake motor having a motor and a brake device. The monitoring portion also determines a state of the brake device based on the state information and a control signal output by a brake motor controller that operates the brake motor or adjusts a control current supplied to the brake device.
Claims19
An apparatus for monitoring a brake motor, comprising:
- a monitoring portion configured to measure state information of the brake motor including a motor and a brake device, and determine a state of the brake device based on the state information and a control signal of a brake motor controller configured to operate the brake motor or adjust a control current supplied to the brake device,
- wherein the monitoring portion includes:
- an alternating current (AC) current measuring instrument configured to measure an AC current supplied to a rectifier configured to convert the AC current into a direct-current (DC) current supplied to the brake device;
- a DC current measuring instrument configured to measure the DC current supplied to the brake device through the rectifier;
- a relay configured to selectively cut the AC current supplied to the rectifier;
- and
- a monitoring controller configured to transmit a state of the AC current and the DC current based on a control signal of the brake motor controller to the brake motor controller, determine a state of the brake device based on the state of the AC current and the DC current based on a control signal of the brake motor controller, and operate the relay.
