STATOR FOR CONCENTRATED WINDING MOTORS AND CONCENTRATED WINDING MOTOR

摘要

PROBLEM TO BE SOLVED: To enable efficient transmission of heat from a coil to the yoke of a concentrated winding motor without bearing a high cost.;SOLUTION: A stator for concentrated winding motors is constructed by taking the following measure in the stator 24 of a motor 21 in which teeth 24c are extended from multiple places at intervals in the direction of the circumference of an annular yoke 24b to the direction of the radius of the yoke 24b: there are provided multiple swelled parts 24d so formed that they are swelled between adjacent two teeth 24c, 24c of the yoke 24b in the radial direction and respectively arranged between adjacent two teeth 24c, 24c. Each swelled part 24d is formed in such a shape that it does not overlap with at least part of the straight line connecting together the base ends of adjacent two teeth 24c, 24c.;COPYRIGHT: (C)2011,JPO&INPIT
