In any case, if the issue is a result of a failed module or actuator, you will have to order a new one from your dealer. Electromagnetic brakes operate electrically but transmit torque mechanically. Once the EPB is activated, the emergency brake light will illuminate your instrument cluster. In this case the air gap is zero but more importantly the response time is very consistent since there is no air gap to overcome. About Motor Brakes. The reason for this is if burnishing on a two piece is done on a bench and there is a shift in the mounting tolerance when that brake is mounted to the machine the alignment could be shifted so the burnishing lines on the armature or brake face may be off slightly preventing that clutch or brake from achieving full torque. Beyond our core brake technology, KEB is able to offer custom designs which help motor manufacturers during assembly and meet the application requirements. Two EPB mechanisms are presently in production; caliper integrated systems and cable puller systems. Over excitation is used to achieve a faster response time. When power is off, a spring force clamps the friction disc between a pressure plate and a . For most industrial brakes, friction material is then placed over the coil and is set between the inner and outer pole. A decrease in braking torque. Brakes are available in multiple voltages and can have either standard backlash or zero backlash hubs. KEB specializes in the design and manufacture of DC spring-set brakes. Knowing how to fix these problems will save you stress, time, and energy. Advantages of a DC-to-AC motor conversion article, California Transparency in Supply Chain Act of 2010 Disclosures. These incredible Brakes operate on a very simple principle: while the motor is running with power engaged, an electromagnet within the brake pulls back the pressure plate, allowing the friction discs and motor shaft to rotate freely. If a piece of iron contacted both poles a magnetic circuit is created. The brake is applied when the voltage supply is interrupted. 66 0 obj
