NT Motor 230 V

Compact NEMA or Metric Flange AC Servo Motors

The NT motor is a compact, high performance brushless AC servo motor designed to maximize torque and minimize size. The NT motor uses powerful magnets and is manufactured with a segmented core to maximize stator efﬁciency.

These motors are available with direct motor-to-drive connector terminations for Control Techniques' brand Unidrive M, Digitax ST and Epsilon EP servo drives – cable lengths up to 20 ft are available.

Key Features

• Torque range: 7.5 to 56 lb-in (0.85 to 6.3 Nm)

• Very low inertia for high acceleration and cycle rates

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

• Available with or without holding brakes

• Direct connect available – no additional cables required!

• Flying-lead cabling option (ex: NTE-320-LONS-0005)

with improved ingress protection; ﬂying leads

are available with or without MS connectors

• IP65 conformance (IP67S and IP68S optional)

• Standard 2048 encoder

• Installed shaft seal are standard with all motors

• Optional white epoxy food-grade ﬁnish
