Q: What is the cycle life for your electromagnetic brakes or clutch brakes? How can I tell if my brake is worn?
A: The life of the brake is approximately 2 million cycles (reference value) if the electromagnetic brake motor or clutch brake motor is used within our specifications (torque, inertia, speed....etc.). There's no specific indicator that will specify that the brake is worn (like squealing noise of a car brake), but we would recommend replacing brake motors as soon as you notice that it's not operating within the original specifications. Our electromagnetic brake motors typically take 2~3 rotations at the motor shaft to stop completely. Our clutch brake motors typically take 1 rotation at the motor shaft to stop completely. The overruns can be reduced with a gearhead (divide overrun by gear ratio). Since our braking system uses friction, there may be a scraping sound from time to time. This is normal.
