Product Data

This publication provides product information about the 2.3 to 53.0 N-m (20.7 to 469.0 lb-in.) 1326AB 460V Torque Plus Series, AC Servo Motors. 

This publication includes:

• Detailed lists of the features and options available for 1326AB 460V, Torque Plus Series, AC Servo Motors

• Tables that show how to determine the catalog numbers for the motors and options you need

• Performance data and speed-torque curves for all 1326AB 460V Torque Plus Series, AC Servo Motors

• Servo motor dimensions

• Details on holding brakes, shaft oil seal kits, encoder mounting adapters and junction boxes

• High-resolution feedback motors

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.

Feedback Options

1326AB servo motors are available with either resolver (standard) or high-resolution encoder feedback devices. 

Resolver-based servo motors feature:

• A rugged, brushless resolver that provides accurate position feedback, eliminates the need for on-board electronics and can

withstand harsh shock, high operating temperatures, and vibration.

• Resolver feedback generates (2048ppr) A quad B encoder output.

High-resolution servo motors are available in single or multi-turn configurations that provide high-resolution encoder feedback for

applications requiring precise tolerance:

• Single-turn (-S) configuration provides precise machine positions of two million counts per revolution.

• Multi-turn (-M) configuration provides accurate absolute machine positions over multiple revolutions (no batteries needed) to eliminate machine re-homing on

power-up. It provides one million counts of feedback per revolution and absolute positioning within 4,096 revolutions.

• Both configurations feature on-board EEProm memory for storing motor configuration information.

Important: High-resolution feedback can only be used with the 9/440 high-resolution feedback CNC.

Servo Motor Options

Options available for the 1326AB 460V AC Torque Plus Series include (the option code or catalog number is in parenthesis):

• Integral Spring-Set Holding Brakes with 24V DC coils (-K4, -K5, -K7).

• A Shaft Oil Seal kit, (1326AB-MOD-SSV-xx) for installing a Viton shaft oil seal on a motor in the field. Motor disassembly is not required.

When the shaft oil seal is installed, the motor is dust tight, able to withstand pulsating water jets, and meet the IP65 requirements of the IEC 529 standard.

Important: IP67 (-L) servo motors have a factory-installed shaft oil seal and do not require the Shaft Oil Kit option.

• Secondary Feedback Mounting Kits (1326AB-MOD-Mxx) for installing an Allen-Bradley Encoder (845H) in the field.

Note: Not available for high-resolution motors.
