Servo Motors & Drives by Numatics Actuators and Motion Control

The Epsilon Series is the most compact digital servo drive in the Numatics lineup. Designed to fit in cabinets as small as six inches (152mm) deep, with cables attached, Epsilon drives possess rugged quality and reliability. There are three sizes of each Epsilon drive: 2 Amp, 3 Amp and 5 Amp, with the largest drive delivering up to 37 lb-in continuous torque. Each drive contains a 14-segment status display, reset button, removable connectors and utilizes standard “D” type connectors.

Epsilon 120-240V NT Motor Selection The NT motor is a high performance motor utilizing patented technology to maximize torque in a compact package. The NT motor uses powerful Neodymium magnets and manufactured with a segmented core to maximize stator efficiency. The NT motor has a very low inertia for applications that demand high accel and cycle rates. NT motors are available in English (NEMA 23 or 34) flanges, with or without brakes. The standard encoder resolution is 2048 lines per rev. NT motors are supplied with MS style connectors.
