Most Commonly Used Motor Brakes

The three most common brake types are DC brakes, three-phase brakes, and single-phase AC solenoid/linkage brakes, although other types are available.

• DC brake
  The DC brake is an example of a spring-actuated, electromagnetically released motor brake. These brakes use springs to press the armature plate against the brake hub. This squeezes the friction disc (located between the armature plate and the mounting plate) to produce a stop torque.
  When the coil is energized, the friction disc can rotate freely with the hub, attracting the armature plate back to the magnet, which means torque is applied when the power is off. It is well known that DC brakes require less maintenance and adjustment than other types of brakes, in part because linkage or solenoid valves are not involved. They also provide adjustable torque.
• Three phase brake
  A three-phase brake, also known as a phase sensing brake, is another example of a spring-actuated, electromagnetic-release motor brake. The working principle of these induction motor brakes is similar to that of DC brakes because the springs press the armature plate against the brake hub. Instead of using magnets, they use coils to generate electromagnetic fields that pull the armature back.
  Note that when the brake is energized, it pulls the armature and brake lining away from the hub so that the motor can rotate freely. Note that the three-phase torque can be adjusted according to the number of springs used, and their response time is not as fast as the equivalent DC brake.
• Single phase AC solenoid valve/linkage brake
  The design of the single-phase AC solenoid valve/linkage brake is slightly different from that of a DC brake and three-phase brake. To allow the motor to rotate freely, the linear solenoid pulls the mechanical linkage, releases the two pressure springs, and then pulls the pressure plate. Once the pressure plate is pulled up, the friction plate will rotate freely with the hub. However, this spring brake does not support torque adjustment.
  The disadvantage of this brake type is the solenoid valve's limited life and/or the connecting rod due to the wear of moving parts. These brakes should not be used in intensive cycling or precise stopping applications.
