Abstract
(EN)
A stator 40 has: a core back portion 43; a plurality of teeth 44 extending inward in the radial direction from the core back portion; a first system coil portion 46 and a second system coil portion 47 wound around each of the teeth 44; and a magnetic interference reduction member 48 disposed between the first system coil portion 46 and the second system coil portion 47 and reducing the magnetic interference between the first system coil portion 46 and the second system coil portion 47. The first system coil portion 46 and the second system coil portion 47 are connected to a first system power supply source 20 specific for the first system coil portion 46 or a second system power supply source 30 specific for the second system coil portion 47.
