Allen-Bradley MPL-B330P-MJ24AA low-inertia servo motor

DO Supply identifies MPL-B330P-MJ24AA as a low-inertia brushless AC synchronous servo motor in the Allen-Bradley MP Series. The source lists 400 V AC input, 5000 rpm rated speed, a 24 VDC holding brake, and a high-resolution multi-turn encoder.

Documented product role

Rebuilt from individual evidence

DO Supply identifies MPL-B330P-MJ24AA as a low-inertia brushless AC synchronous servo motor in the Allen-Bradley MP Series.

The source lists 400 V AC input, 5000 rpm rated speed, a 24 VDC holding brake, and a high-resolution multi-turn encoder.

The documented product function places this unit between the control system and its connected operator or mechanical interface.

Unknown: installation-specific compatibility, replacement fit, and current commercial availability require separate evidence.

System role

This section explains what the product does and where it acts in the surrounding system.

Function: Converts servo-drive commands into controlled rotary motion for an industrial axis.
System position: Sits between a Kinetix servo drive and the mechanical load in a motion-control axis.
Upstream / inputs: Accepts 400 V AC power, feedback, and brake control from the paired servo drive.
Downstream / outputs: Delivers controlled rotary torque and position feedback to the motion-control system.
Limitations: Unknown: installation-specific compatibility, replacement fit, and current commercial availability require separate evidence.
