Infineon Technologies iMOTION™ IMM100 Digital Motor Controllers

Infineon’s field-proven Motion Control Engine (MCE) implements sensorless Field Oriented Control (FOC) with single or leg-shunt current feedback. This uses space vector PWM with sinusoidal signals to achieve the highest energy efficiency. Additionally, IMM100 can take over the boost Power Factor Correction (PFC) control. Powerful PC tools like MCEWizard and MCEDesigner reduce the implementation effort for a variable speed drive to a simple configuration of the MCE for the respective motor, complemented by script engine for more system-level flexibility. Alternatively, “A”- variants of IMM100 offer full flexibility of running own motor control software on Arm® Cortex®-M0 core, while taking additional advantage of the complete hardware integration.

The integrated gate driver provides the bootstrap capability, adds signal filtering and offers several hardware protection mechanisms. These mechanisms include dead-time insertion and shoot through prevention, over current, over/under voltage protection and fault reporting. The IMM100 series does not require a heatsink and addresses motor drives with a rated output power up to 30W/60W/80W with 600V maximum DC blocking voltage.
