About our Servomotor Brakes

Nexen offers a full line of Eclipse® servomotor brakes that mount directly to the servomotor flange for increased safety.

Selection 
With a large selection of models, several bore sizes, and a variety of mounting configurations and torque offerings, make retrofitting on existing machines quick and easy. Many options of flanged Eclipse® servomotors save you time, conserve resources, and lower inventory costs.  

Simple Installation
The brake flange replicates the servomotor flange, so no accommodations are needed. Simply slide the brake between your motor and gearbox and tighten the shaft collar. Operators will appreciate the true pilot mounting and seamless integration with IEC or NEMA frame motors.

Easy Maintenance
While field serviceable, the long-facing life and lubrication-free operation of the Eclipse servomotor brake make it virtually maintenance-free. Nexen's Servomotor Brakes simplify machine maintenance by holding the load during motor change-outs, even in power-off situations.

Washdown Protection
Sealed housings offer environmental protection and meet IP67 dust and waterproof standards. Optional nickel plating is available.

Smooth Torque Transmission
Double-taper facing locks down on the housing and rotor to create a zero-backlash torque transmission interface.

Cool Operation
Standard electric brakes generate heat when disengaged, lowering the unit's efficiency. The air-release Eclipse design adds no heat, provides cool operation and long life, and requires no energy, resulting in higher, more consistent torque capabilities.

Rugged Strength
A One-piece, solid shaft increases torsional rigidity and overhung load capabilities.

Low Inertia
One-piece rotor/shaft assembly lowers inertia and eliminates spline for zero backlash.

Nexsafe® Safety Rated
Nexen's Spring Engaged, Air Released Servomotor Brakes are available and are safety-rated to comply with international safety standards ISO 13849-1. Category Level up to 4 and Performance Level up to e can be achieved using Nexsafe® products in the recommended configuration. Contact Nexen for safety-rated versions of spring-engaged, air-released servomotor brakes.

Zero Backlash
The split-hub clamp collar makes installation easy and prevents backlash for smooth stopping and precision holding.
