1326AB-B720E-21-ML

The 1326AB-B720E-21-ML is a ferrite AC Servo Motor from the Torque Plus series, manufactured by the Allen Bradley branch of Rockwell Automation to meet the needs of motion systems with high performance. The housing of this three-phase motor is made of aluminum for better heat transfer, and it is specially designed to simultaneously reduce the length of the motor, which is around 20 inches (508 millimeters), and increase the ratings of continuous torque (it has a motor and system continuous torque of 30.9 N-m). This synchronous brushless module, the 1326AB-B720E-21-ML, has a voltage of 460 to 380 Volts AC and is engineered to be used in combination with the Allen-Bradley 1394 Motion Control System. The rating of the output torque of the motor at the stall is zero RPM (100% continuous torque). The 1326AB-B720E-21-ML weighs 46.3 kilograms (102 pounds), and the diameter of the frame of the motor is 194 millimeters (215 millimeters bolt center). This motor can achieve a speed of 3500 RPM, and it has an IP67 Environmental Rating which protects the motor from a temporary immersion in water. The 1326AB-B720E-21-ML can be mounted vertically and at any angle, and the IEC Metric Flange shaft with a Keyway can be turned up or down; its position will not affect the operation of the motor.

This servo motor comes with an onboard EEPROM memory and is available with a high-resolution encoder feedback device in multi-turn configurations. This aforementioned memory is used to store information about motor configuration. The multi-turn configuration means that re-homing of the machine on power-up is eliminated thanks to accurate machine positions over multiple revolutions. It is important to note that the motor comes with a pre-installed shaft oil seal, and it loses the IP67 rating if either a junction box kit option or an encoder package, which is mounted externally, are used. The user needs to makes sure that the ambient temperature does not exceed 40 degrees Celsius (104 degrees Fahrenheit), otherwise the 1326AB-B720E-21-ML might deteriorate.
