Abstract: An electric motor includes an insert member situated within an insert bore formed in a rotor in order to adjust a balance of the rotor. The insert member has a body part provided with a cutout portion in a part of its circumference to define a gap extending therebetween. The insert member also has a pair of inner protrusions protruding radially inwardly from the opposite side edges of the gap. The size of the gap is determined such that the gap is not closed when the insert member elastically deforms and as a result, the outer diameter of the insert member becomes smaller than the diameter of the insert bore.

Abstract: An IPM type rotor having a continuous skew structure obtained by a simple means, without constituting a permanent magnet as a complicated shape and forming an inclined magnetizing pattern on the permanent magnet. A rotor core has a recess formed on an outer circumferential surface of the rotor core. The recess is formed so as to extend along a boundary line of magnetic poles of a desired skew structure. Therefore, even when each permanent magnet has the cuboid shape, the magnetic flux may be uniformed during the magnetic flux is transmitted through the magnetic steel plate having high permeability, whereby the magnetic flux within the gap having low permeability becomes dominant. As a result, the rotor having the continuous skew structure is obtained.
