Title:
ROTARY ELECTRIC MACHINE
Document Type and Number:
Japanese Patent JP2023037849
Kind Code:
A
Abstract:
To provide a rotary electric machine which can improve output density without a large size.SOLUTION: A motor 1 includes a cylindrical stator 2 extending in an axial direction and a rotor 3 positioned inward of the stator 2 in a radial direction. The stator 2 includes: a cylindrical stator core 11 having a plurality of teeth 13 protruding radially inward; and a stator coil 21 wound around the plurality of teeth 13 by concentrated winding to configure a plurality of parallel circuits. The inner peripheral side of the stator core 11 has such a shape that a first gap part S1, having a small radial gap between the rotor 3 and itself, and a second gap part S2, having a larger gap in the radial direction than the first gap part S1, are formed when the stator core 11 is looked in the axial direction.SELECTED DRAWING: Figure 1
