Solution Description


This complete 3-phase motor drive inverter solution implements field-oriented control (FOC) of sinusoidal-shaped permanent magnet synchronous motors (PMSMs), 

It provides an affordable, easy-to-use solution for driving high power motors for a wide range of applications such as white goods, air conditioners, compressors, power fans, and generally 3-phase inverters for motor drives, with nominal power from 1200 W to 2500 W

It consists of a digital control block with STM32G431RB microcontroller that generates signals for the intelligent power module (IPM) based on FOC algorithms and current and motor speed feedback signals from the IPM and motor, which are conditioned by the TSV994 Op-Amp into suitable microcontroller peripheral inputs.

  • STIB1060DM2T-L (10 A, 600 V, 0.18 Ohm typ.,  Power MOSFET)
  • STIB1560DM2T-L (15 A, 600 V, 0.15 Ohm typ.,  Power MOSFET)
  • STGIB20M60TS-L  (25 A, 600 V short-circuit rugged IGBT)
  • STGIB30M60TS-L    (35 A, 600 V short-circuit rugged IGBT)

The second series of SLLIMM (small low-loss intelligent molded module) provides a compact, high-performance AC motor drive in a simple, rugged design. The FOC algorithms for the solution can be developed using the STM32Cube Motor Control Software Development Kit (X-CUBE-MCDK) with graphical interface for setting up and generating algorithm code and more

  • Key Product Benefits
