Original Press Release:
IR's New HiRel iMOTION(TM) Motor Drive Module Eliminates Software Development in High Performance Motors
EL SEGUNDO, CA., October 2006- International Rectifier, IR® (NYSE: IRF), a world leader in power management technology, today introduced the IRMCT3UF1, a fully-integrated high-reliability (HiRel) hybrid motor control module enabling digital, sensor-free vector control of permanent magnet motors. Based on IR's iMOTION(TM) 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.
"Compared to complex DSP- or microprocessor-based solutions that require position sensors and sophisticated programming, the iMOTION platform simplifies motor control design for aerospace systems," said Michael Toland, Power Modules Product Marketing Manager of International Rectifier's HiRel Products. "It is estimated that up to one man-year of motor control system design can be saved eliminating the laborious code development associated with digital motion control," he added.
The module can be quickly configured to specific applications using the iMOTION ServoDesigner(TM) tool that facilitates drive parameter modification via memory-mapped registers. The control functions are contained in a powerful, pre-configured Motion Control Engine(TM) (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 new HiRel iMOTION module is a greatly simplified solution featuring high efficiency, reduced size and EMI suppression. It is built into IR's 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 eight-square-inch, 2.5-ounce package.
The IRMCT3UF1 provides accurate high performance speed and torque control without commutation or position sensors. Optimized sinusoidal current control enables current startup sequencing and low loss space vector pulse-width modulation (PWM) for smoother startup and minimized torque ripple for maximum motor efficiency.
