PROBLEM TO BE SOLVED: To properly suppress a magnetic flux of a rotor from reaching a coil to a slot of a stator.SOLUTION: A collar 45, having a shape which protrudes to circumferential both sides, is formed at the end of the internal peripheral side of each tooth 44 of the stator, and cross section of the tooth 44 are formed into shapes which are formed, by eliminating four corners from rectangular shapes, when viewed in the radial direction of the substantially cylindrical stator. According to such a configuration, the tooth 44 can be formed by filling a space between the tooth 44 and a coil end, and the cross section of the tooth 44 can be secured, when viewed in the radial direction of the stator without making small a slot region of the stator and the coil. As a result, it is possible to properly suppress the magnetic flux of the rotor from reaching the coil wound to the slot of the stator. |
