Brake Motor

The brake motor is a fully enclosed self-fan-cooled squirrel cage type three-phase asynchronous motor with an additional disc type DC brake. The electric brake motor has the advantages of rapid braking, simple structure, high reliability and strong versatility. ATO.com online store offers optional rated power 1hp/ 2hp/ 3hp/ 5.5hp/ 7.5hp/ 10hp/ 15hp brakr motor, rated voltage 380V (380V~480V can be customized), 2P/ 4P can be chosen. In addition, the brake has a manual release mechanism, 3 phase brake motor is widely used in various mechanical equipment and transmission devices that require quick stop and accurate positioning.

What is Brake Motor?

The electromagnetic brake motor uses electromagnetic suction to work, and it needs to be connected to the power supply before it starts to work. However, there are restrictions on working conditions, that is, the altitude does not exceed 1000 meters, the temperature is -15-+40 °C, and the startup does not exceed 6 times per minute. The electromagnetic brake motor adopts a high-quality aluminum alloy shell, which has the advantages of small size, light weight, stable operation, accurate positioning, high work efficiency, and convenient maintenance.

The DC disc brake of the electromagnetic brake motor is installed on the end cover of the non-shaft extension end of the motor. When the brake motor is connected to the power supply, the brake also works at the same time. Due to the effect of electromagnetic suction, the electromagnet attracts the armature and compresses the spring, the brake disc is disengaged from the end cover of the armature, and the motor starts to run. When the power is cut off, the brake electromagnet loses its magnetic attraction, and the spring pushes the armature to press the brake disc. Under the action of the friction torque, the motor stops immediately. 

Brake Motor Working Principle

The DC disc brake of the brake motor is installed on the end cover of the non-shaft extension end of the motor. When the brake motor is connected to the power supply, the brake motor also works at the same time. Due to the effect of electromagnetic suction, the electromagnet attracts the armature and compresses the spring, the brake disc is disengaged from the end cover of the armature, and the brake motor starts to run. When the power is cut off, the electromagnet of the brake motor loses its magnetic attraction, and the spring pushes the armature to press the brake disc. Under the action of the friction torque, the brake motor stops running immediately; ratio) motor. The power supply of the brake motor is supplied by the rectifier in the motor junction box, AC220V-DC99V for 3kW and below, AC380V-DC170V for 4kW and above (special cases can also be designed according to the manufacturer's requirements such as DC24V) YEJ series electromagnetic brake motor, It can realize rapid braking after the motor loses power. The fast braking time of YEJ2-63-90 motor is less than 0.15 seconds, and that of YEJ-100-160 motor is less than 0.20 seconds. The braking motor can realize slow braking by changing the wiring of the junction box according to user requirements. This series of motors has low noise and reliable braking performance. Its working principle is: when the brake motor is energized, the brake motor obtains 198V DC through 220V AC rectification. At this time, the armature is electromagnetically attracted, so that the brake disc is in a rotatable state and the brake motor is free to rotate. When the brake motor loses power, the electromagnet loses power, and the armature is immediately supported by the spring, so that the brake disc and the rear end cover of the motor are pressed together and stop rotating.
