Title:
BRUSHLESS MOTOR AND MOTOR FOR ELECTRIC POWER STEERING DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/221121
Kind Code:
A1
Abstract:
A brushless motor 1 used as a power source for an electric power steering system, the brushless motor 1 having a stator 2 and a rotor 3. The stator 2 is provided with twelve teeth 8 and two systems of windings 6 wound around the teeth 8, the two systems having different energization systems. The rotor 3 is provided with ten or fourteen magnets 13. The windings 6 are disposed so that windings having the same phase and different energization systems (e.g., U1a(+) and U2b(-)) are disposed adjacent to each other, and at one location in each energization system, windings belonging to the same energization system (e.g., U1a(+) and W1a(+)) are disposed adjacent to each other. The sets P of windings 6 belonging to the same system disposed adjacent to each other are installed at locations facing each other at 180° in relation to the stator center O.
