About our Electric Servomotor Brakes

With a selection of standard industry frame sizes, common bore sizes, and a variety of mounting configurations, Nexen’s new Evolve Electric Servomotor Brakes offer the spring engaged, electrically released solution for a more robust machine design.

Standard Voltage Option        
Available in 24 VDC

Frame Sizes
Industry-standard 155 mm, 125 mm, and 100 mm frame sizes

Zero Backlash Holding
Nexen utilizes a flexible rotor and flexible discs for true Zero Backlash up to 100% of holding torque.

Zero Backlash Clamp Collar
The easy-to-install split-hub shaft collar, with a backup keyway, prevents backlash for smooth stopping and precision holding up to and beyond the minimum holding torque.

Ease of Installation
An air gap is set at the factory, so there's no need for initial adjustment or fine-tuning in the field. Rated torques are achievable out of the box.

Overhung Load
Double Row Angular Contact Bearing delivers high overhung load capacity and axial rigidity.

Environmental Protection
Sealed housing meets IP65 dust and waterproof standards.

Manual Release Option
The built-in lever will allow the brake to be manually disengaged in the event that power is unavailable or equipment needs to be repositioned.
