Working principle and application of brake motor

Brake motor is totally enclosed fan cooled squirrel cage with additional disk type DC brake 3-phase asynchronous motor, DC disc brake for braking motor installed in the non motor shaft extension end of the end cover. When the brake motor access power, the brake motor also works simultaneously. Due to the role of the electromagnetic suction electromagnet attracts the armature and the compression spring, brake disc on the armature end cover disengaged, brake motors started the operation. When the power supply is cut off, and motor braking electromagnet lose magnetic suction spring to push the armature to compress the brake disk, in under the action of friction torque and motor brake immediately stop running; our factory also produce corresponding ydej double speed (speed, far pole ratio) motor. Brake motor power rectifier supplied by the motor terminal box, 3 kilowatts and below AC220V-DC99V, 4 kW and above AC380V-DC170V (special can also be in accordance with the requirements of the factory design such as (DC24V) > YEJ series electromagnetic braking motors, can motor power loss after quick braking. The fast braking time YEJ2-63-90 motor is less than 0.15 seconds, the YEJ-100-160 motor is less than 0.20 seconds, the brake motor can be based on the user's request to change the terminal box wiring to achieve slow brake. The series motor has small noise and reliable braking performance.. Its working principle is: when the brake motor is energized, the motor braking by 220V AC rectifying get 198v direct current, then armature is an electromagnetic attracting so that the brake disk is in a rotating state, and the brake motor to rotate freely. When the electric motor braking electromagnet energized, the armature is immediately spring to withstand, the brake disc and the motor rear pressing together, stop turning cover.

The brake motors are widely used in the mechanical equipment and the transmission device which require quick stop and accurate positioning.. Brake motor with JB/T6456-1992 standard, the series brake motor is widely used in metal processing machine tools, packaging machinery, woodworking machinery, food machinery, chemical machinery, textile machinery, construction machinery, gear reducer and so on. It has the advantages of rapid braking, simple structure, high reliability, and versatility.. Moreover, the brake motor has the artificial release mechanism (60-90 no artificial release mechanism)
