NT MOTOR—230V

NT

The NT Motor is an economical, high performance
motor manufactured to maximize torque and minimize
size. The NT motor uses powerful Neodymium magnets
and is manufactured with a segmented core to maximize
stator efficiency and further reduce size.

Servomotors

 Very low inertia for applications that demand high
accel and cycle rates

 English (NEMA 23 or 34) or Metric (IEC- 72-1) flanges

 With or without holding brakes

 The standard encoder resolution is 2048 lines per rev.

 NT motors can be ordered with MS style connectors,

1 meter Flying Leads or 1 meter Flying Leads with
MS connectors, direct connect

 All models are rated IP65

Continuous Torque

 Medium inertia options

 NT motors are now available with direct motor

to drive connector terminations for Epsilon EP,
Unidrive SP & Digitax ST. (These low cost DP/DS
solutions are not suitable for all applications.)
