1326AB-B740C-21-MK7
The Allen-Bradley/Rockwell Automation 1326AB-B740C-21-MK7 servo motor is an AC-powered Bulletin 1326 Torque Plus series servo motor. This servo motor can operate with low levels of inertia due to its internal ferrite magnets. The 1326AB-B740C-21-MK7 servo motor’s ferrite magnets have specially engineered flux profiles that smoothly increase the motor’s servo response and they are installed in a stack that is 4 inches long. Its continuous stall current rating is 20.9 Amps and its highest peak stall current rating is 50 Amps. The 1326AB-B740C-21-MK7 servo motor comes with a holding brake, a multi-turn encoder, and a metric flange.

The 1326AB-B740C-21-MK7 servo motor is an Allen-Bradley servo motor that is part of the 1326 AB series. It is used in industrial automation systems around the world. These motors are used for dynamic performance. This servo motor has increased reliability and it leverages high-volume production. This AC servo motor has an encoder which is used with the controller to deliver closed-loop control and feedback. The servo motor can be used where the application demands accuracy and precise control. The 1326AB-B740C-21-MK7 servo motor runs with variable voltage ratings. The voltage applied to the device determines the operating speed of the device. When it is supplied with 460 Volts AC, it runs with a speed rating 2200 rpm whereas it runs with 1800 rpm when 380 Volts AC voltage is supplied to the motor.
The 1326AB-B740C-21-MK7 servo motor is a 3-phase device. The magnetic stack length of this servo motor is 4 inches. A 24 Volts DC coil is used in the holding brake that is equipped in the device. A multi-turn high-resolution feedback encoder is equipped in the servo motor which sends feedback to the users throughout the operation time. It provides real-time motor performance to the control system by using serial communication. The 1326AB-B740C-21-MK7 servo motor is made of stainless steel and it is placed inside a frame with a 194-millimeter diameter. The bolt center has a diameter of 215 millimeters. The motor is manufactured to endure higher voltage tolerance which in turn delivers higher torque. The servo motor is used in automation and other applications where high levels of precision and accuracy are required. The 1326AB-B740C-21-MK7 servo motor has been optimized to meet different drive ratings for efficient system sizing. The device can withstand harsh shocks, high operating temperatures, and high levels of vibration.
