    摘要: A two-phase unipolar driving brushless DC motor of a radial gap type having a rotor position detector (100) includes a main-pole yoke (17) having main-poles (17A), an interpole yoke (13) coaxially provided with the main-pole yoke (17) in a superposed manner and having interpoles (13A) and an axial short-circuit portion or member (14) provided in an axially extending portion in magnetic fluxes (F) formed in the main-poles (17A) and interpoles (13A). This structure allows for easy winding of coils (15) around the main-poles (17A) and enhanced winding space factor in order to increase the starting torque and to improve the motor efficiency.
