For the high precision driving, a multi-coil-motor (MCM) driven by digital-direct-drive-technology has been proposed. However, it is not suitable for driving MCM, since this digital-direct-drive-technology aims driving of speaker. This paper proposes two methods for a high precision driving. First method is ahoneycomb-structured space vector delta-sigma modulation which can realize a multilevel quantization on a rotating coordinate system. Second method is a full-search dynamic three-phase multi-coil-motor matching which can reduce the influence of variations of a manufacturing of stator coils.Key Words : Realization of high precision motor, Reduction of torque ripple, Reduction of quantizationerror, Reduce the influence of element variations, Multi-Coil-Motor, Space vector modulation
