Outline of Final Research Achievements

A novel three-phase motor, whose coils are divided by several sub-coils, and digitally direct driven method for the motor have been proposed. The motor can realize high power, high efficiency, and low power supply motor system. The performance degradation caused by mismatch among sub-coils are improved by using a noise shaping dynamic element matching method (NSDEM) proposed by us. Moreover, a degradation caused by a mismatch among the three phase coils are also improved by proposed new NSDEM for whole coils consisting a three-phase motor, which controls driving coils in order to realize rotating magnetic field using all three-phase sub-coils. A low torque ripple and high-power efficiency with low power supply motor system can be available by using proposed method.
