Product Description

The MSM957141-36 is part of a family of fully integrated smart motor solutions for servo motor applications. This 57mm (NEMA 23), 141W power motor integrates a brushless DC motor and driver module.  The user can choose from one of three options: speed control mode, position control mode, or speed/position control mode. Two control interface options are available: an RS485 interface or a PULSE/DIR interface.

Easy-to-use GUI software provides flexibility as it allows users to flexibly optimize the design online through the RS485 control interface. The parameters are saved in the motor’s non-volatile memory. A design guide for the GUI is available for download at

In addition to the fully integrated smart motor solutions, the driver modules can be ordered separately for customization into different motor types. The MMP757141-36 is the driver module part number.
