MSM957141-36 eMotion SystemTM Smart Motor Family Position/Speed/Torque
The MSM957141-36 is part of a family of fully integrated eMotion SystemTM 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 www.monolithicpower.com
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 MMP757141-36 is the driver module part number.

Field Oriented Controller with High Accuracy Angular Sensor
The MP6570 is a high-performance controller using a field-oriented-control (FOC) method and an accurate, on-chip, angular sensor. The MP6570 can be used in applications with 3-phase PMSM and BLDC motors. The FOC control is used to achieve high performances of motors and provides higher dynamic response, lower torque ripple, and higher efficiency. The MP6570 can be operated in position control, speed-control mode, or torque-control mode. The reference command comes from the digital interface input or external single-input signal either in clock or PWM input. The motor 3-phase current is sampled and digitalized to the current/torque control loop by a 10-bit ADC. With the FOC algorithm, the motor 3-phase winding voltage is modulated through the SVPWM module, which has up to 12-bit resolution at 40kHz switching frequency. The on-chip angular sensor uses MPS? high-speed and accuracy angular sensor for rotor position and speed feedback. It has up to 500kHz data refresh rate and 10-bit position resolution, ideal for BLDC and PMSM motor controls, especially in application (i.e.: high-speed control and high-position accuracy servo). The MP6570 has non-volatile memory, which is flexible for parameters programmed through a standard I2C interface. Additionally, all controls and designs with the MP6570 can be easily done with MPS? GUI software. The MP6570 has robust failure mode protection features including over-current protection (OCP), over-temperature protection (OTP), and input
