STMicroelectronics is claiming an industry first with the unveiling of a customizable motor-control module that is small enough to mount directly on the motor, in addition to providing connection via industrial Ethernet.
Developed in conjunction with motion-control specialist Robox, the SPIMD20 can drive brushless 3-phase motors up to 2kW. The module includes ST’s 1200V/40A IGBT power switches and the TD352 gate driver. Two STM32 microcontrollers provide a 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 full control over the motor-control algorithm and type of Ethernet fieldbus.
