MPL-B4520P-RK22AA

The MPL-B4520P-RK22AA servo motor is an Allen-Bradley servo motor that belongs to the low-inertia MPL series of servo motors. This MPL series low-inertia servo motor is a rotary AC servo motor with a brushless rotor. This brushless servo motor is ideal for applications requiring a lot of torque and fast acceleration. The MPL-B4520P-RK22AA servo motor is fitted with a premium permanent magnet that supports quick acceleration and high levels of torque because of its innovative winding technology. The motor has a rated operating speed of 5000 RPM. The MPL-B4520P-RK22AA servo motor comes in a compact 130-millimeter frame size with a 2-inch magnet stack length. The 460 Volts-rated windings of this servo motor yield a motor torque of 6.1 N-m. The shaft-end of the MPL-B4520P-RK22AA servo motor has a threaded hole for mechanical connections, but the shaft itself does not come with a shaft key.

The Allen-Bradley MPL-B4520P-RK22AA MPL series permanent magnet servo motor supports resolver type feedback, which is only available in some of the MPL series servo motors. Unlike incremental and absolute feedback motors, resolver motors have lower accuracy levels but they are more durable and more suited for applications in extreme conditions than other servo motors. The MPL-B4520P-RK22AA servo motor does not have a holding brake option. It includes 2 bayonet connectors that can accommodate feedback and power cables. Another motor accessory that is available for this low-inertia servo motor is the shaft seal kit. A shaft seal kit is not included as a standard feature with this servo motor and it has to be ordered separately if it is needed. Installing a shaft seal increases the motor’s environmental protection rating from IP 50 to IP 66. The MPL-B4520P-RK22AA servo motor is mounted by using an IEC metric mounting flange that contains free mounting holes.
