Servo Motor Description

Torque Plus motors feature a specially engineered housing that reduces motor length and increases continuous torque ratings. 

These high performance, three-phase, brushless, AC, synchronous servo motors are designed by Allen-Bradley to meet the stringent

requirements of high performance motion systems. This series of 460V, AC servo motors is intended to be used with the Allen-Bradley

1394 Motion Control System.

Each servo motor features:

• Special flux profile permanent magnets engineered by Allen Bradley to increase servo response.

• A three-phase, sinusoidal-wound stator field for smooth operation at low speeds.

• TENV construction. IP65 is standard. IP67 (-L) option is available with optional shaft seal (1326AB-MOD-SSV-xxx) installed.

• An extruded aluminum housing for improved heat transfer.

• 100% continuous-rated output torque at stall (zero rpm).

• A UL Listed insulation system (file #E57948).

• The ability to be vertically mounted at any angle with the shaft up or down.

• A normally closed thermal switch in the motor winding (rated 115V AC/ 24V DC at 1A) that provides thermal overload indication.

• A precision balance of 0.0127 mm (0.0005 in.) total peak-to-peak displacement.

• A CEI/IEC 72-1 metric flange mount with metric shafts.

• A threaded hole on the face of the shaft for securing couplings.
