STMicroelectronics Customizable Motor-Mounted Module SPIMD20

STMicroelectronics has unveiled a customizable high-end motor-control module that is small enough to mount directly on the motor, in addition to providing connection via industrial Ethernet. The SPIMD20 can drive brushless 3-phase motors up to 2kW, and is ideal for various industrial applications.

Developed in conjunction with motion-control specialist Robox, the module combines ST’s reliable high-performance semiconductor technologies, including 1200V/40A IGBT power switches and the TD352 - gate driver. Two STM32 microcontrollers provide a powerful processing engine for motor control and networking functions. A real-time communication interface supporting protocols such as EtherCAT and CANopen DS402 is provided. Basic firmware supporting network connectivity and featuring PWM driving, current loop and speed-loop execution synchronized to the fieldbus is also available.

The module supports full customization of firmware and logic, allowing designers to full control over the motor-control algorithm and type of Ethernet fieldbus. “The SPIMD20 combines custom configurability, high performance, and the convenience of distributed control for the first time in an off-the-shelf module,” said Matteo Lo Presti, Group Vice President and General Manager, Systems Lab & Technical Marketing, Industrial and Multisegment Sector, STMicroelectronics “This combination of features is a breakthrough in motion control that will enable developers to reduce engineering costs, cut time to market, and quickly scale their designs as markets and opportunities evolve.”
