ALL EN-BRADLEY 1326AB High Performance AC Servo motors

The 1326AB Servomotors are a family of high performance, three-phase,brushless AC synchronous motors designed by Allen-Bradley to meet thestringent requirements of servo system applications. This series of standardAC servomotors can be used with 1391 AC Servo Controllers. The performance parameters of these motors with selected amplifiers are listed onpage 8. The typical speed-torque curves (see page 9) depict the operational envelope of these motor and controller combinations.Each motor has the following standard features:•Permanent magnet rotor for increased servo response.

•Three-phase sinusoidal wound stator field for direct transfer of heat toambient, and smooth operation at low speeds.

•Brushless resolver supplies position, commutation & velocity feedbackinformation. This also provides durability in harsh environments by nothaving on-board electronics in the motor. 1391 A Quad B (optional)encoder output (up to 2048 ppr) is generated via resolver feedback.

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

•Precision balance of 0.0005” (0.0127mm) total peak-peakdisplacement.

•Vertical shaft up or down mounting.

•TENV construction.

•IP65 rated (when used with the Shaft Seal option) to withstand harshenvironments. Motor is dust-tight and able to withstand pulsating waterjets without liquid entering the motor.Important: 1326AB motors lose the IP 65 rating when externallymounted encoder/resolver feedback or blower packages are used.

•Normally closed thermal switch in the motor winding (rated 115V AC at1A, 24V DC at 1A) provides thermal overload indication.

•Environmentally sealed power and feedback cable packages. Power andresolver feedback cables can be ordered as standard (flex), track(multi-flex) or extended length (ES).

•MIL spec connectors are standard.

•Ferrite magnets for cost effective performance.

•UL recognized insulation system (file # E57948).
