Abstract
[PROBLEMS] To provide a motor for EPS which can exhibit a desired performance while satisfying severe limitation on physical size.[MEANS FOR SOLVING PROBLEMS] In a motor for a rack assist type electric power steering system arranged coaxially around a rack shaft coupled with a steering wheel and supplying a steering assist force to the rack shaft, the motor has a six-pole, nine-slot structure and the loading ratio (2PΦ/(ZI/a)) of its magnetic loading (2PΦ) to electric loading (ZI/a) is set in the range of 100-300. Consequently, a motor for EPS in which physical size, output, steering feeling, cost, and the like, are satisfied in good balance can be obtained. Since a numeric value conforming to EPS specification is set for the loading ratio, specification at each part of the motor can be determined in accordance with that value, resulting in optimization of design or reduction in manhour of design.
