Abstract: There is disclosed an electric motor comprising: a plurality of windings (7a to 7f) wound around a stator core (5); a plurality of winding terminal receiving portions (8a to 8f) for containing terminal portions (9a to 9f) of a plurality of windings (7a to 7f) in a peripheral direction of the stator core (5) at an interval; a terminal plate (21) for containing lead wires (23) drawn out of the plurality of windings (7a to 7f) along the peripheral direction of the stator core (5); and connection fittings (10, 24) for electrically connecting the winding terminals (9a to 9f) to the corresponding lead wires.

Abstract: A compressor comprising a compressing mechanical unit which inhales a refrigerant excluding chlorine, compresses the refrigerant, exhales a compressed refrigerant, and collects a refrigerating machine oil O compatible with the refrigerant, thereby lubricating the compressing mechanical unit with the refrigerating machine oil O, and an electric motor unit having a stator and a rotor, for driving the compressing mechanical unit, the stator being constituted by winding a wire on a stator core, wherein the stator core includes a yoke section and teeth sections, and the wire is directly wound on the teeth sections.

Abstract: A method of magnetizing a permanent magnet motor involves inserting a spacer in between multi-layered windings (24Ua and 24Va) wound on a plurality of magnetic pole teeth when magnetizing an unmagnetized magnet (26), and removing the inserted spacer (28A) after finishing the magnetization. The spacer (28A) is also inserted in a space between two stator windings (24Ua, 24Va; 24Ub, 24Vb) wound on two magnetic pole teeth adjacent to each other, a magnet material is magnetized by electrifying the stator windings with a direct current in a state of the spacer (28A) being inserted, a permanent magnet is thus formed, and the spacer (28A) is removed after finishing the magnetization.
