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.

Band brakes are the simplest electric brake configuration. Although many electric brakes use mechanical methods for actuation others rely upon friction. Dc injection braking provides a quick and smooth braking action on all types of loads including high speed and high inertia loads. Figure 1 dc injection braking of a motor.

Some customers prefer this brake as it is modular and the gearbox brake and motor can all be serviced or replaced individually. Recall that opposite magnetic poles attract and like magnetic poles repel. Typical applications include robotics holding brakes for z axis ball screws and servo motor brakes. Also known as hysteresis clutches these couplings use magnetic force to brake control tension and prevent torque overload.

Brakes are used to reduce or cease the speed of motors. This principle when applied to both ac and dc motors is the reason why the motor shaft rotates. Brakes are available in multiple voltages and can have either standard backlash or zero backlash hubs. The type 17 brake is offered with a variety of different magnet voltages and includes a conduit box for making the wiring connection.

They have few moving parts so they last longer than mechanical couplings. Each is described below. There are several types of frictional brake devices. There are 2 main types of holding brakes.

They are often used as a back stop mechanism to prevent reverse rotation. This brake is typically mounted in between a nema c face motor and a gearbox.
