Abstract
A rack-assist type electric power steering device (10) uses a motor (1) as a drive source. The stator (11) of the motor (1) includes a stator core (13) having ring-like yoke portion (16) and teeth (17) projecting from the yoke portion (16) in the inner direction. In the stator core (13), the ratio (Wy:Wt) between the width (Wy) of the yoke portion (16) in the radial direction and the width (Wt) of the teeth (17) in the circumferential direction is 1:1.4 to 1.8. By setting the yoke portion (16) and the teeth (17) of the stator core (13) to this value, the stator core (13) can be set such that torque slack is difficult to occur within a restricted space
