Motors & Drives Information

Higher performance brushless servo motors from Parker EME are designed to replace the now obsolete N-Series motors recently discontinued by Rockwell Automation/Allen-Bradley. Parker Electromechanical have launched the MPN-series of brushless servo motors, designed to replace the now-obsolete N-Series motors which were recently discontinued by Rockwell Automation/Allen-Bradley. The Parker MPN motors offer more torque per-frame size than the N-Series motors, feature well-proven technology from the Parker MaxPlus motor family range, and are modified to match the mechanical mounting and electrical characteristics of the Rockwell N-Series family.

The front motor mount, shaft dimensions, connectors and the electrical Ke (back-EMF) of the motors are identical to that of the N-series motors, and the rotor inertias are typically within 10% of the equivalent N-Series motor - so there is unlikely to be a any need for retuning.

One minor drawback is some of the motors may be slightly longer than their N-Series equivalent.

The use of neodymium magnets permits the MPN-series motor to generate significantly higher torques, with the Kt (torque constant) of some MPN motors being twice that of the equivalent N-Series motor.

Consequently MPN motors require less current, less energy, and generate less heat, while providing higher performance and ultimately greater throughput.

Since these motors have the same mounting, connectivity, and very similar electrical characteristics to the N-series motors, it is very easy to retrofit MPN-series motors in existing N-series applications.
