Product Description

The MSM957094-36 is part of a family of fully integrated eMotion SystemTM smart motor solutions for servo motor applications. This 57mm (NEMA 23), 94W 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 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 eMotion SystemTM smart motor solutions, the driver modules can be ordered separately for customization into different motor types. The MMP757094-36 is the driver module part number.

3-Phase BLDC Controller with a High-Accuracy Angular Sensor

The MP6570 is a high-performance motor controller that incorporates field-oriented control (FOC) algorithms, SVPWM modulation technology, and an accurate embedded angle sensor. The MP6570 is used for applications with three-phase PMSM and BLDC motors.

The operation of the MP6570 supports three modes, including speed mode, position mode, and torque mode. The reference command comes from either the digital interface or the pulse-width modulation (PWM)/clock input pin. A 10-bit ADC is employed for accurate sampling of each phase current. The three-phase voltage of the motor is modulated through an SVPWM module, which has up to 12-bit resolution at a 20kHz switching frequency.

A high-speed, high-accuracy magnetic angular sensor is embedded in the IC for rotor position and speed feedback. The position sensor has a data refresh rate up to 1MHz and up to 14-bit position resolution, ideal for BLDC and PMSM motor controls, especially in applications that require high speed or position accuracy.   

Non-volatile memory (NVM) is employed in the MP6570 to store parameters programmed through the selectable I2C, SPI, or RS485 digital interface.

Application design is aided by the eMotion SystemTM Virtual Bench online developer tool.

Full protection features include over-current protection (OCP), rotor-lock protection, and input bus over-voltage (OVP) and over-current protection (OCP).

The MP6570 is available in a QFN-32 (4mmx4mm) package.

eMotion SystemTM Smart Motor Control Board for Servo Motor Applications for Speed and Position Control, Requires the eMotion SystemTM Communicaiton Kit and eMotion SystemTM Virtual Bench Software

The MMP757094-36 is part of a family of eMotion SystemTM smart motor control boards for servo motor applications. This design is capable of delivering 94W continuous power and is designed to fit NEMA 23 format 57mm motors.

The board features an:

- Embedded angular sensor,

- FOC control

- Selectable position, speed and torque loop mode

- RS485 and PULSE/DIR input interface.

The user can choose from three options: speed control mode, position control mode, or speed/position control mode.

Easy-to-use GUI software allows users to flexibly optimize the design online through the RS485 control interface. The parameters are saved in the control boards non-volatile memory.

User can also order a complete motor (MSM957094-36).

This control board requires the eMotion systemTM communicaiton kit and eMotion systemTM virtual bench software.
