Nexen Brakes Said to Use Less Energy
- Published: March 08, 2016
VADNAIS HEIGHTS, MN | Nexen Group offers the Eclipse Servo Motor Brakes said to provide distinct advantages over spring-engaged, electrically released brakes.
Company says no energy is consumed when the brake is disengaged, and it is spring-engaged/air-released (no electric coil) to keep the brake cool until it’s needed. 
Brakes are designed to mount to the shaft end of servo motors up to 20 hp, 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 and 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.
Reported features and benefits of the brakes include the following:
- Fail-safe, power-off engagement
- High torque
- Zero backlash for accurate holding
- Integral flanges adapt to any servo motor or AC motor brand and mounting style
- High torsional rigidity, no system windup
- Models configured to hold the machined end of a ball screw
- Can be used for intermittent dynamic stopping
- Spring engaged for holding and E-stop applications
- High-speed capability–engineered and balanced for servo applications.
