Motor Controller Features Arm Cortex-M0 MCU

Infineon Technologies has released its new IMC300 motor
controller series. It combines the iMOTION Motion Control Engine (MCE) with an
additional microcontroller based on the Arm Cortex-M0 core. IMC300 complements
the IMC100 series and aims at variable speed drives that require very high
application flexibility. Both families, IMC100 and IMC300, share the same
implementation of the MCE 2.0 providing ready-to-use motor and, optional, PFC
control. Applying the MCE for controlling the motor, customers can focus on
their system application that runs fully independently on the embedded Arm
microcontroller.

Infineon’s field-proven MCE 2.0 implements highly
efficient field-oriented control (FOC) of permanent magnet synchronous motors
(PMSM). The MCE integrates all required hardware and software building blocks
as well as all necessary protection features resulting in a reduced bill of
material (BOM). It undergoes continuous improvements with typically two
releases per year. The autonomous MCU offers a flexible peripheral set and can
serve a multitude of purposes like system functions, specific communication or
drive monitoring. IMC300 devices are pre-certified for applications requiring
functional safety according to UL/IEC 60730 (‘Class B’).

IMC300 derivatives are offered for motor drives with and
without PFC control. Devices in LQFP-64 packages (shown) are in mass
production, and LQFP-48 types will be released in the second quarter 2020.
Rapid prototyping of a drive inverter is enabled via two new control boards for
the iMOTION Modular Application Design Kit (MADK). MADK is a modular and
flexible development platform providing a range of control and power board
options for motor drive applications up to 1kW.
