ROTATING FIELD TYPE ELECTRIC MOTOR

摘要

PROBLEM TO BE SOLVED: To provide a rotating field type electric motor decreasing a difference of resistance between each winding to simplify a structure and make assembly workability improvable. SOLUTION: A stator 1 for a brush-less motor winds a winding 6 in each phase to a plurality of teeth 4. The winding 6 has three phases, the winding 6 of each 1 phase is respectively connected and arranged over a plurality of the teeth 4. The winding 6 in each phase is connected to an input part of each phase inputting one end 6a from the outside. After winding to the last tooth 4 is ended, the other end 6b of the winding 6 in each phase is axially extended and connected to the common terminal part between the teeth 4. A fitting part 8 over a circumference is formed in upper/lower both ends of an external peripheral surface of each insulator 5 almost cylindrically provided in an outer side end part of the teeth 4. A brass-made C-shaped bar 9 is pressure fitted to the fitting part 8. A bar 9 is formed in circular arc shape of 240 deg. or more. One end 6a and the other end 6b of the winding 6 are arranged in an upper side of the stator 1.
