Abstract
A pole plate includes first to third pole pieces formed into one piece. The second pole piece has grooves respectively formed in edges of two long sides of a first surface. Since a ratio of a width of the groove to a width of the pole plate falls between 0 and 0.15, the width of the groove is far smaller than the width of the pole plate. In a width direction of the pole plate, there is a long distance between the two grooves, as well as long distances from a middle of the second pole piece to the two grooves. Therefore, when the two grooves are machined, extrusion on the middle position of the second pole piece can be effectively reduced, and the middle position of the second pole piece is not broken for the extrusion, which does not waste machining cost and improves a machining efficiency.
