Electric Motor Brake Types

Recall that opposite magnetic poles attract and like magnetic poles repel.

Electric motor brake types.

Brakes are used to reduce or cease the speed of motors. This brake is typically mounted in between a nema c face motor and a gearbox. Brakes are available in multiple voltages and can have either standard backlash or zero backlash hubs. Figure 1 dc injection braking of a motor.

Typical applications include robotics holding brakes for z axis ball screws and servo motor brakes. Although many electric brakes use mechanical methods for actuation others rely upon friction. Each is described below. They have few moving parts so they last longer than mechanical couplings.

There are 2 main types of holding brakes. Band brakes are the simplest electric brake configuration. 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.

There are several types of frictional brake devices. Some customers prefer this brake as it is modular and the gearbox brake and motor can all be serviced or replaced individually. Twist the adjustment ring to set the torque within the range listed then lock the ring in place with the included set screw. 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.

This principle when applied to both ac and dc motors is the reason why the motor shaft rotates. For technical drawings and 3 d models click on a part number.
