Electric Motor Brake Types

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.

Electric motor brake types.

Recall that opposite magnetic poles attract and like magnetic poles repel. 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. Each is described below.

Figure 1 dc injection braking of a motor. Dc injection braking provides a quick and smooth braking action on all types of loads including high speed and high inertia loads. Twist the adjustment ring to set the torque within the range listed then lock the ring in place with the included set screw. Some customers prefer this brake as it is modular and the gearbox brake and motor can all be serviced or replaced individually.

This brake is typically mounted in between a nema c face motor and a gearbox. Brakes are used to reduce or cease the speed of motors. There are several types of frictional brake devices. Band brakes are the simplest electric brake configuration.

They have few moving parts so they last longer than mechanical couplings. Typical applications include robotics holding brakes for z axis ball screws and servo motor brakes. The type 17 brake is offered with a variety of different magnet voltages and includes a conduit box for making the wiring connection. Also known as hysteresis clutches these couplings use magnetic force to brake control tension and prevent torque overload.

Although many electric brakes use mechanical methods for actuation others rely upon friction. There are 2 main types of holding brakes.
