New iMOTION Appliance-Motor Control Mitigates Growing Energy Crisis in China
Estimates are that more than half of all electricity in China powers motors. The traditional mechanical control scheme wastes half of the electricity it uses. Inverterbased, variable-speed-drive designs can save most of these losses.
Advancing the adoption of inverter-based variable speed drives requires finding a means to achieve mechanical simplicity while maintaining the performance necessary to meet high-efficiency goals. A new iMOTION chipset consists of a unique MCE (Motion Control Engine) and a dedicated high-voltage IC to drive a PM (permanent-magnet) motor. This paper presents the chipset in the context of an air-conditioner design with corresponding test data.
