1326AB-B530E-21-K5

The 1326AB-B520E-21-K5 is a servo motor manufactured by Allen-Bradley that is used to implement control of motion of a motor driven actuator particularly in the field of robotics, packaging and product manufacturing, material handling and other applications.

This Allen-Bradley servo motor is a 3-Phase, Brushless, AC servo motor with a braking mechanism installed as indicated by the catalog number.

With the braking accessory installed, the drive is capable of holding a load even at rest as well as provide braking torque in emergency stopping situations. The additional accessory provides the motor with a brake response time of 150 ms. pickup and 25 ms. dropout. The Holding torque provide by this component is rated at 13.6 N-m or 120 lb-in. When energized, this component draws a DC current of 1.20 amperes with an added weight of 4.08 kilograms or 9.0 pounds. It provides additional inertia to the servo motor on top of the inherent designed inertia. The added inertia amounts to 0.0031 (0.0027) kg-cm-s1 (lb-in.-s2) while having a cold resistance of 21 Ohms.

Ensure that the brake mechanism is not energized and de-energized higher than 90 times within an hour using as parking brake. The intended function of a parking brake is maintaining hold of a stationary load and not as motor stopping brake. Aside from unpredictable power interruptions, the parking brake should not be used in other application. It is ideal to install a back-up power source to equipment or devices that must be properly stopped, or shutdown should a power interruption occurs. The Allen-Bradley 1326AB-B530E-21-K5 is a ferrite AC Servo Motor with a frame diameter of 149 mm, a bolt center of 165 mm, and a magnet stack length of 30. It has a voltage rating of 460V AC, as well as rated speeds of 2500 rpm at 380V AC and 3000 rpm at 460V AC. This motor comes with an IEC metric flange with a keyway for its shaft and mounting and a 13.6 N-m or 120 pounds on an inch holding brake that features a 24V DC coil. Note that this motor should be mounted vertically and at any angle with its shaft up or down. This brushless, three-phase 1326AB-B530E-21-K5 motor is a Torque Plus series motor intended for use with 1391 Digital AC Servo Drives that focus on a high-performance motion and also have a 230V AC input. Both the motor-rated torque and system continuous torque of the 1326AB-B530E-21-K5 motor are the same, at 18 Nm when equipped with 1394-AM50 and 1934-AM75 axis modules, but its system continuous torque drops to 14.2 N-m or 126 pounds on an inch if using a 1394-AM07 axis module. This motor also has a system continuous stall current of 7.5 A and system peak stall current of 15 A when used with a 1394-AM07 axis module, as well as a 9.5 A system continuous stall current and 28.5 A system peak stall current when a 1394-AM50 or 1934-AM75 axis module is connected to the motor. The 1326AB-B530E-21-K5 also has a 100% continuous rated output torque at a stall or at 0 rpm and a rated output of 4.2 kW.
