    摘要: A binder fiber comprising a polyamide component in at least part of a surface thereof is prepared. The polyamide component contains a semi-aromatic polyamide at least having an aromatic ring unit and a C3-7 alkane unit which may have a branched CA 1-3 alkyl chain. In the binder fiber, the polyamide component may be (a) a semi-aromatic copolyamide having an aromatic ring unit, a C3-7 alkane unit which may have a branched C1-3 alkyl chain, and a C8-12 alkane unit which may have a branched C1-3 alkyl chain. The polyamide component may be (d) a combination of (b) a semi-aromatic polyamide and (c) a semi-aromatic polyamide, wherein the polyamide (b) has an aromatic ring unit and a C3-7 alkane unit which may have a branched C1-3 alkyl chain, and the polyamide (c) has an aromatic ring unit and a C8-12 alkane unit which may have a branched C1-3 alkyl chain.

    摘要: In the permanent magnet motor of the present invention, where P is an integer not smaller than one, the number of magnetic poles of a rotor (22) is set to 2P, and the number of salient poles of a stator field core (21) is set to 3P. The salient pole section (21a) of each stator field core (21) is provided with two supplemental grooves (24). A salient pole magnetic interpolar angle is 4.theta., such that two supplemental grooves (24) of each salient pole section (21a) are arranged in positions at angles of .theta. and 3.theta. with respect to the center of a winding slot (27) in the circumferential direction of the rotor. With this structure, a fundamental wave component of a clogging torque is removed and a permanent magnet motor having a low clogging torque is provided.
