STMicroelectronics has released two reference designs that simplify building complete industrial or home-appliance motor drives for compressors with the STSPIN32 motor-control system-in-package (SiP). Each integrates the motor controller with a three-phase inverter to power the motor, and an offline converter and auxiliary circuitry. A production-ready PCB design and motor-control firmware are also included. The STEVAL-CTM011V1 targets general…
