MPL-A320P-MJ74AA

The Allen-Bradley MPL-A320P-MJ74AA Kinetix Servo motor is part of the low-inertia MP series. Unlike Direct On-line (DOL) and Variable Frequency Drive (VFD) controlled motors, the MPL-A320P-MJ74AA is used to implement motion and position control.

The MPL-A320P-MJ74AA is specifically a Brushless AC synchronous motors. It generally features a high Torque to size ratio with low inertia. When equipped with an appropriate Kinetix Servo drive controller, this servo motor may be configured to be part of Allen-Bradley’s smart motor technology.

The compact and small body of this servo motor is ideal for applications with limited installation space. By default, it has a protection rating of IP55 however, it may be meet IP66 rated protection when installed with the MPL-SSN-A3B3 shaft seal.

The MPL-A320P-MJ74AA servo motor is powered by an external voltage supply of 230VAC. It is designed to operate up to 5000 revolutions per minute (rpm) with rated speed of 4750 rrpm. It provides an output current of 9.0 amperes while its output power is rated at 1.3 kW and continuous stall Torque rating of 3.05 N-m. Additionally, it has a roto inertia of 0.000078 kg-m2.

The MPL-A320P-MJ74AA is provided with a 24VDC holding brake. This is used to provide the motor the dynamic braking capabilities which is an important aspect of motion and position control. Additionally, it uses SpeedTec DIN connectors for establishing incoming connections to the servo motor. This connector is industrially approved to provide secure wiring and connections as well as easy to install, contributing to shortened installation time and faster commissioning of the product.

This holding brake needs to be used with a different power source than the servo motor in order for the servo motor to take advantage of its protective benefits. It is important to know that, in order to extend the life of the MPL-A320P-MJ74AA servo motor, it is recommended to perform periodic revisions that indicate whether a part needs to be replaced or if it is working in optimum condition. It is also important to determine whether the servo motor has good protection and ventilation level or not. The Allen-Bradley MPL-A320P-MJ74AA permanent-magnet rotary servo motor needs to be installed in a non-corrosive environment without any hazardous materials. It is important to prevent contact with liquids if the motor does not have a proper housing, shield, or shaft seal kit applied to it. The Allen-Bradley MPL-A320P-MJ74AA permanent-magnet rotary servo motor has a rated speed of 5000 rpm and it requires a voltage level of 200 Volts AC in order to work properly.
