Brake motor is made of two parts consisting of three-phase asynchronous motors and brakes, its belongs to three-phase asynchronous motor derived series. Manual brake release and bolt release are two forms of brakes.Brakes are the main components of the brake motor .Its working power divided into two categories; One is AC brake, the other is DC braking, my company produces brake motors are DC brake motors, the advantage of the braking torque is below, Easy installation, braking response speed, high reliability, versatility and other advantages.
Working principle
After the motor is equipped with a cover asbestos friction disc wear-resistant materials and excitation coil. When the motor is energized by a spring brake friction disc is a pressing plate, pressing firmly on the plane after the motor cover has been processed, so that the brake disc friction torque generated strong achieve braking purposes. When the excitation coil is energized to produce electromagnetic suction, pull the spring-loadedplate, pressed board leave the friction plate. The friction disc is released, the, motor flexible rotation, depending on the motor power between tens to hundreds of European coil resistance.
The DC brake can not be directly connected to the AC power to the brake coil is provided with suction cups for low-voltage winding rated DC voltage.A single-phase AC power is rectified then supply to a sucker winding to make it work,so the brake motor terminal box fitted with a rectifier, wiring diagram below.
The breaking time
Brake motor braking time(t)is the time from the motor and brake stopping the power to the shaft completely stopped, under normal circumstances, For 63 to 80 frame size motor, the braking time is 0.5 seconds, For 90-132 frame size motor, the braking time is 1 second, For 160 to 180 frame size motor, the braking time is 2 seconds.THE INVERTER RUNS THE MOTOR BRAKE
With the continuous development of social productivity and the continuous improvement of science and technology. Braking plus frequency conversion has been widely used in actuators. All asynchronous motors produced by our company can be configured with frequency converters for operation. At this time, the brake must provide a stable working power supply separately, and cannot be connected in parallel with the power supply terminals on the motor. Otherwise, the brake will not work properly. It should be pointed out that when the brake motor is equipped with frequency conversion operation, an axial flow fan must be added, and this fan can only be controlled and powered independently.
It is worth noting that the maximum frequency range of all asynchronous motors produced by our company is 60Hz. If users have special requirements, they can make them to the company.
With the continuous improvement and continuous development of the social productivity of science and technology. Brake plus inverter system has been widely applied in the implementation of the organization.I produced all asynchronous motors can configure the drive to run. At this point the brake must be provided separately stable power supply, and then can not be shared with the power terminals on the motor. Otherwise the brakes do not work properly. Need to make is brake motors with variable frequency operation, an axial fiow fan to attach this fan only independent control and power.
Notably, the company produces all kinds of asynchronous motor in the highest frequency range 60Hz,as you may have special requirements please let us know.
