Servo Motor Brake


Motion Control nexen servo motor

With Nexen’s servo motor brake, no energy is consumed when the brake is disengaged.

Nexen servo motor brakeNexen’s Eclipse servo motor brakes are designed to mount to the shaft end of servo motors up to 20 horsepower, including NEMA 23, 34 and 42 frame sizes. The brake’s square-shaped housing allows flexibility to custom make the mounting features match the motor dimensions. The brake’s output end duplicates the motor mounting features. The input end bore accepts the motor shaft and is fixed inside the brake with a split-hub/shaft collar arrangement. No energy is consumed when Nexen’s servo motor brake is disengaged. It is spring-engaged/air-released (no electric coil) to keep the brake cool until it’s needed. Key features of the Eclipse servo motor brakes include a torque range of 2 to 125 Nm, high torsional rigidity and zero backlash for accurate holding.
