Motor drive module eliminates software development in high performance motors

24 January 2007 Analogue, Mixed Signal, LSI

International Rectifier′s new fully-integrated high-reliability (HiRel) hybrid motor control module enables digital, sensor-free vector control of permanent magnet motors. The IRMCT3UF1 is based on the company’s iMOTION integrated design platform and its greatly simplified approach to code development.

The new module combines digital control, analog interface and power stage, streamlining time-to-market and increasing design flexibility to accommodate drive system changes in high-reliability applications.

The module can be quickly configured to specific applications using the iMOTION ServoDesigner tool that facilitates drive parameter modification via memory-mapped registers. The control functions are contained in a pre-configured motion control engine (MCE), and its algorithm accommodates motor parameter variation for compatibility with a variety of brushless DC and permanent magnet AC motors, while creating robust field oriented control.

In contrast to conventional motion control circuits, the HiRel iMOTION module is a greatly simplified solution featuring high efficiency, reduced size and EMI suppression. IR has built it into its rugged, high-density plastic ring frame package, and screened to various test methods of MIL-STD-883 for operation in severe environmental conditions. Less than half the size of a discrete solution, the module combines digital controller, memory, external interface, gate drivers, and six power MOSFETs into a 51 cm² package.
