The 1326AB-B740E-S2LS motor is a 460 Volts AC rated motor with 12.7 kilowatts of output power and 3400 RPM of rated rotor speed. It is designed and manufactured by Allen-Bradley and it belongs to the 1326AB Torque Plus series. The motor comes in an enclosure which is IP 67 rated because it contains a factory-installed shaft seal kit that protects the motor from dust and enables it to be protected against pulsing jets of water. A single-turn encoder is provided on the motor and it provides precise machine positions within 2 million counts per shaft revolution. The high-resolution single-turn encoder enables the motor to be used with 9/400 CNC. The frame diameter of the motor is 194 millimeters and 40 millimeters is its magnet stack length.

The 1326AB-B740E-S2LS motor can perform according to the specifications for ambient temperatures not exceeding 104 degrees Fahrenheit. The performance specifications for the motor include 2800 to 3400 RPM at 380 to 460 Volts AC, a continuous stall torque of 50.8 N-m with the AM50/75 modules, a peak stall torque of 52.7 to 79.4 N-m with the AM50/75 axis modules, a continuous stall current of 20.9 Amps with the AM50/75 modules, and a peak stall current of 33.2 to 50 Amps with the AM50/75 axis modules. The insulation class of the motor is Class H and the thermal time constant is 60 minutes. The torque constant and inductance ratings for the motor winding are 2.11 N-m and 4.6 Millihenry, respectively. The motor should only be installed and serviced by experienced technicians. The maintenance of the motor should be performed according to the guidelines provided by Allen-Bradley.
