Motor Brakes

Teknic launched its Spring Applied, Power-Off Motor Brakes, available in NEMA 23 (3/8-inch shaft diameter) and 34 frame (½-inch shaft diameter) sizes. The motor brakes will prevent axes from moving or stop axes already in motion. They have NEMA-standard input/output mounting flanges, with a front mount compatible with Teknic’s integrated servos (ClearPath), standalone brushless servo motors (Hudson), and stepper motors with or without encoders. They feature zero backlash and low inertia and a current draw of less than 500 milliamps. They have a maximum input speed of 6000 RPM, with an maximum engage time of 10ms (after 24VDC is removed) and a 20ms disengage time.
