Orientation device and magnetization device |
摘要 |
To provide an orientation device capable of efficiently orientating resinous magnets filled in slits of a rotor core.An orientation device comprising a plurality of permanent magnets 5 disposed at the same intervals as slits 2 in the rotor core 1 with their magnetic poles of the same polarity adjacent to each other, along the outside circumference of a rotor core housing section 4 for housing the rotor core 1, and a plurality of pole pieces 6 disposed between the plurality of permanent magnets 5, wherein the width of the pole piece 6 at the end 6a on the side of the rotor core housing section 4 is no larger than the maximum width alpha max of an outermost slit 2a of the rotor core 1 between opposite ends thereof.
