Nexen Expands Line of High-Torque Servo Motor Brakes to over 140 Models



Vadnais Heights, MN — Nexen Group, Inc. has launched an expansion of their Eclipse® line to offer more than 140 variations of spring-engaged, air-released servo motor brakes for a wider range of servo motors. Eclipse brakes offer four times the torque of internal servo motor brakes, and offer at least 20-50% more torque than competitive brakes, providing greatly enhanced holding power for demanding applications.



The Eclipse line offers flanges ranging from 57 mm (2.25 in) to 265 mm (10.43 in) square and shaft diameters from 6,35 mm (0.25 in) up to 48 mm (1.89 in). Nexen offers their expanded range of low-inertia brakes for all major servo motor models up to 20 HP.



"The Nexen Servo Motor Brake design is elegantly simple, sturdy and sound,” said Edd Brooks, Senior Technical Sales Representative, Nexen Group Inc. “This flange mounted brake is confidently applied by engineers in most industries and out-performs all competitive brakes. This is a product that is easy to apply and performs beyond expectations."



The new models offer advantages to a more diverse range of industrial applications including packaging machinery, food production, machine tools, conveying systems, CNC machining centers, automotive production equipment, and woodworking. The holding power and positioning accuracy of Eclipse brakes also complement Nexen Roller Pinion System (RPS) systems.



Other features of Nexen Eclipse servo motor brakes include:

High-torque (2-125 Nm)

NEMA 23, 34, and 42 frame sizes

High torsional rigidity

Long facing life
