Motor control ICs integrate hardware and algorithm for variable speed drives

The IMC100 family of iMotion motor control ICs from Infineon, are now available from distributor, Mouser Electronics.

The ICs are for high-efficiency, variable-speed drives and integrate both the required hardware and control algorithm for a permanent magnet synchronous motor (PMSM).

The Infineon IMC100 series motor control ICs are based on Infineon’s Motion Control Engine (MCE), which implements field-oriented control (FOC) and eliminates 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 achieve its high energy efficiency.

The IMC100 ICs also provide protection features like over- and under-voltage, over-current, rotor lock to safeguard the motor and power stage. The IMC100 devices provide flexible communication interfaces, including UART, SPI, I2C, analogue input, frequency input, and CAN.

The IMC100 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 evaluation system that provides a scalable design platform for three-phase motor drives ranging from 20 to 300W. The EVAL-M1-101T evaluation control board and EVAL-M3-102T evaluation board connect to the iMOTION MADK and are capable of providing three-phase modulation or type three of two-phase modulation.

Infineon describes its iMotion IMC100 series ICs as particularly suitable for motor control applications in home appliances, air conditioning units, fans, and pumps.
