The 1326AB-B740E-M2K7L servo motor from the Allen-Bradley 1326AB Torque Plus product line is a 3400 RPM rated AC synchronous servo motor. The Torque Plus motors features a special housing that reduces the length of the motor while increasing the torque ratings. Torque Plus series motors support 20.7 to 469 pounds on an inch (2.3 to 52 N-m) torque ratings. These motors have an input rating of 460 Volts AC. Additional motor features include the standard IP 65 motor enclosure rating, permanent magnets, precision balance, and vertical mounting support. The 1326AB-B740E-M2K7L servo motor has a 40-millimeter magnet stack length and a frame diameter of 194 millimeters. The feedback comes from a high-resolution multi-turn encoder. Also included with the motor is a 140 pounds on an inch holding brake which includes a 24 Volts DC coil.

The 1326AB-B740E-M2K7L servo motor is designed for optimal operation at ambient temperatures of up to 40 degrees Celsius. Motor operation at higher temperatures is not recommended because the motor output will derate. The approximate weight of the 1326AB-B740E-M2K7L servo motor is 170 pounds. The motor winding specifications include a torque constant rating of 18.7 pounds on an inch, an inductance rating of 4.6 Millihenry, a terminal resistance of 0.26 ohms, and a voltage constant of 127.5 rms. Each of these winding specifications is specified for a 25 degrees Celsius operating temperature. The rated speed of the 1326AB-B740E-M2K7L servo motor is 3400 RPM at 460 Volts AC input and 2800 RPM at 380 Volts AC input. The rated output power is 12.7 kilowatts. The electrical time constant for the motor is 14.3 milliseconds. The peak stall torque with AM50/75 axis modules is 466/702 pounds on an inch. The continuous stall torque with AM50/75 axis modules is 450/450 pounds on an inch.
