PMSM/BLDC motor controller with additional 32-bit microcontroller

iMOTION™ motor controller with Motion Control Engine (MCE 2.0), scripting and Arm® Cortex®-M0 MCU in QFP-64 package.

The IMC301A-F064 is a highly flexible control solution for variable speed drives based on a dual core device.  The motor controller performs sensor less field oriented control (FOC) for a variable speed drive based on a permanent magnet synchronous motor (PMSM). The integrated MCU is based on an 32-bit Arm® Cortex®-M0 core and is used to implement customer functionality.
