1326AB-B730E-21MK7

The Allen-Bradley 1326AB-B730E-21MK7 servo motor is a brushless servo motor. This servo motor, like other servo motors in the Allen-Bradley 1326AB series, accommodates the use of inline gearboxes which provide increased torque. The inline gearboxes have low backlash and high efficiency for machine positioning accuracy. Additionally, by having a unique design, the gearbox mounts easily on the face of 1326AB servo motors without the need for a special shaft, special tools, or even special flange tolerances. Note that the gearbox adds no more than 10 inches to the motor’s overall length. The 1326AB-B730E-21MK7 servo motor has a frame diameter of 5.88 inches, a NEMA metric flange with a keyway, and a holding brake with a coil powered by a 24 Volts DC power source plus a torque of 400 pounds on an inch. The brake is powered separately. Note that a single brake power supply can power up to 4 brakes. However, if independent control of multiple motors is desired, 1 brake power supply per motor must be used.

For the 1326AB-B730E-21MK7 servo motor, the brake’s power supply must be able to produce a minimum current of 0.88 Amps and a maximum current of 1.2 Amps. The 1326AB-B730E-21MK7 servo motor contains a multi-turn high-resolution feedback encoder. The 1326AB-B730E-21MK7 servo motor, like other motors in the same series, supports the use of encoder mounting adapters. When interfacing the 1326AB-B730E-21MK7 servo motor with an industrial application, consider factors such as the conveyor, leadscrew, rack, and pinion when determining the maximum speed that is required. Additionally, the value of the minimum continuous motor torque and the maximum continuous motor torque that is needed to accelerate the load should also be factored in.
