Title:
CONCENTRATED WINDING DYNAMO-ELECTRIC MACHINE, AND ELECTRIC VEHICLE
Document Type and Number:
Japanese Patent JP3800686
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a concentrated winding dynamo-electric machine with a small, light body and high efficiency, together with an electric vehicle with the dynamo electric machine.
SOLUTION: A concentrated winding dynamo-electric machine has a stator 2 ad a rotor 3 with polarities at intervals. The stator 2 includes a stator winding 5, a stator winding salient pole 42 with a concentrated stator winding 5 and a stator yoke part 41 that constitutes a magnetic flux path for the salient pole 42. In addition, the stator winding salient pole 42 in a stator core 4 has a space part 45 for limiting magnetic flux in a circumferential direction, while the outer circumferential part of the stator core 4 has space part 44, for limiting the magnetic flux in the circumferential direction.
