Motor control ICs integrate hardware and algorithm for variable speed drives

The IMC100 series, from Infineon Technologies, is a new family of iMOTION motor control ICs now in stock from Mouser. These ready-to-use solutions for high-efficiency, variable-speed drives integrate both the required hardware and control algorithm for a permanent magnet synchronous motor (PMSM). The ICs are based on the company's proven Motion Control Engine, which implements field-oriented control (FOC) and excludes software coding from the development of motor control algorithms. The FOC uses single or leg-shunt current feedback and space-vector PWM with sinusoidal signals to deliver high energy efficiency. The ICs also offer protection features like over and under-voltage, over-current, rotor lock to safeguard the motor and power stage. The devices offer highly flexible communication interfaces, which includes UART, SPI, I2C, analogue input, frequency input, and CAN. The series ICs are supported by the iMOTION Modular Application Design Kit for motor control (iMOTION MADK), EVAL-M1-101T evaluation control board, and EVAL-M3-102T evaluation board. The iMOTION MADK is a compact and flexible evaluation system that gives a scalable design platform for three-phase motor drives ranging from 20W to 300W. The evaluation control board and evaluation board connect to the iMOTION MADK and are capable of providing three-phase modulation or type 3 of two-phase modulation.
