Allen Bradley 1326AB-B520F-21-K5 Used Surplus

The 1326AB-B520F-21-K5 is a motion / position control equipment that is typically installed in the manufacturing, packaging, material handling and other applications that require precise control of position of an actuator.

This product is designed by Allen-Bradley which in particular an AC Servo motor designed with a 380 / 460VAC armature voltage, with an embedded resolver feedback which is the key to perform motion control. Compared with an AC induction motor, this type of motor operated only at maximum and Zero (0) speed. If used with a Variable Frequency Drive (VFD), the motor is added with a speed control feature. A servo motor on the other hand is automatically equipped with a feedback device to monitor the rotation or the actual degree of position of the motor. This feedback is high-resolution feedback which can be further improved for applications that require a higher level of precision. These higher resolution feedback devices are accessory of the product such as Allen-Bradley 845H encoder and 9/440 high-resolution feedback CNC.

The 1326AB-B520F-21-K5 is an Allen Bradley Servo Motor, classified under the 1326AB motor series. This servo motor comes with a Frame diameter of 149 mm and the maximum motor speed is 3,500 RPM. The 1326AB-B520F-21-K5 comes with an IEC Metric Flange with Keyway flange and shaft series and a rated motor voltage of 460/380 Volts AC. This motor’s motor rated torque is 13.1 N-m and a rated output of 2.9 Kilowatts. The motor supports System Continuous Torque of 13.1 N-m while the system peak stall torque for the motor is 39.3 N-m. The standard option for the 1326AB-B520F-21-K5 servo motor by Allen Bradley is 13.6 N-m Holding Brake w/24 Volts DC Coil. The 1326AB-B520F-21-K5 features a specially engineered housing designed to offer a reduced motor length and also increases the motor`s torque ratings. Being a high-performance brushless three-phase motor, the 1326AB-B520F-21-K5 has been specially designed to meet the stringent demand by the high-performance motion systems. As a member of the 1326 Series motors, the 1326AB-B520F-21-K5 has been engineered for use with the Allen Bradley 1394 Motion Control Systems. The 1326AB-B520F-21-K5 comes with special flux profile magnets manufactured by Allen Bradley and included to ensure the motor offers increased servo response. The motor also comes with a three-phase sinusoidal-wound stator and this makes it a special smooth operator even at the low speeds. The extruded aluminum housing offers an improved heat transfer with 100% continuous rated output torque. For additional flexibility, the 1326AB-B520F-21-K5 can be installed vertically at an angle with the shaft facing either upwards or downwards. There is also a threaded hole on the face of the 1326AB-B520F-21-K5 shaft that allows securing of the couplings. The ambient operating temperature for the 1326AB-B520F-21-K5 is 40 degrees Celsius while the disc type brake for the 1326AB-B520F-21-K5 is spring-set when power is disconnected. The 1326AB-B520F-21-K5 integral holding brake is designed to enable holding a load at rest and also provides for limited braking torque to ensure emergency braking.

This servo motor is rated IP65 which means it is a dust tight and water jets protected. The housing of this servo motor may go all the way up to IP67 rated protection. In some application, the servo motor may lose the inherent IP ratings if used with an external mounted servo motor package. In this situation, the user must provide the external protection for the servo motor accordingly.

This servo motor is designed with an integral disc brake that is set by a spring when power is removed.

The breaks primary purpose is to hold the motors load at rest and provide braking torque for emergency stopping situations.
