Datasheet

The IMC100 series which is a new family of iMOTION motor control ICs from Infineon Technologies is now being shipped by Mouser Electronics. 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 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 high energy efficiency.

Protection features including over- and under-voltage, over-current, rotor lock safeguard the motor and power stage. The IMC100 devices provide highly flexible communication interfaces, including UART, SPI, I²C, analog input, frequency input, and CAN.

Support comes in the shape of 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 provides a scalable design platform for three-phase motor drives ranging from 20W 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 3 of two-phase modulation.

Applications for the ICs include motor control applications in home appliances, air conditioning units, fans, and pumps.
