Electric motor brake types.

Figure 1 dc injection braking of a motor. There are 2 main types of holding brakes. Although many electric brakes use mechanical methods for actuation others rely upon friction. Twist the adjustment ring to set the torque within the range listed then lock the ring in place with the included set screw.

There are several types of frictional brake devices. We know that there are various types of motors available dc motors induction motors synchronous motors single phase motors etc and the specialty and properties of these motors are different from each other hence this braking methods also differs from each other but we can divide braking in to three parts mainly which are. They are often used as a back stop mechanism to prevent reverse rotation. Dc injection braking provides a quick and smooth braking action on all types of loads including high speed and high inertia loads.

Band brakes are the simplest electric brake configuration. Multiple disks can also be used to increase brake torque without increasing brake diameter. They have few moving parts so they last longer than mechanical couplings. This principle when applied to both ac and dc motors is the reason why the motor shaft rotates.

Brakes are used to reduce or cease the speed of motors. Brakes are available in multiple voltages and can have either standard backlash or zero backlash hubs. This brake is typically mounted in between a nema c face motor and a gearbox. Some customers prefer this brake as it is modular and the gearbox brake and motor can all be serviced or replaced individually.

Typical applications include robotics holding brakes for z axis ball screws and servo motor brakes. Recall that opposite magnetic poles attract and like magnetic poles repel.
