A compressor motor and a method for magnetizing a rotor thereof are provided. The compressor motor includes a stator and a rotor configured to electromagnetically interact with the stator to be rotated, wherein the rotor includes a core, a plurality of magnets inserted into the core, and a cover configured to cover both end portions of the core and to be injection-molded so as to fill accommodation spaces that are formed between the core and the plurality of magnets.

Compressor motor and method for magnetizing rotor thereof

A motor is provided. The motor includes: a rotor; a stator inside which the rotor is rotatably disposed and including a plurality of teeth protruding toward the rotor; a plurality of insulating films disposed in respective slots formed between the plurality of teeth to insulate a coil wound around the plurality of teeth from the respective teeth; and insulating members covering upper and lower portions of the stator, respectively, wherein the plurality of insulating films are fixed by the plurality of teeth and the insulating members.

A three-way flow control valve for refrigeration cycles having two parallel heat exchangers is disclosed. This valve is designed to selectively feed refrigerant to both heat exchangers, or one of the two heat exchangers as desired. The three-way flow control valve of this invention consists of a hollow cylindrical casing opened at its first and second ends. A first valve housing is held in the first end of the casing, and is provided with a first refrigerant outlet and a first orifice formed in the first refrigerant outlet. A second valve housing is held in the second end of the casing, and is provided with a refrigerant inlet and a second refrigerant outlet, and a second orifice formed between the refrigerant inlet and the second refrigerant outlet. A first valve means is axially set within the first valve housing so as to be axially movable to control the opening ratio of the first orifice. A second valve means is axially set within the second valve housing so as to be axially movable to control the opening ratio of the second orifice. An actuation means is set between the first and second valve housings while allowing the two valve housings to communicate with each other, and actuates the first and second valve means.

Three-way flow control valve

A motor having permanent magnets received therein includes a rotor having a plurality of circular sheet irons deposited in turn, a plurality pairs of magnet receiving slots formed through the deposited sheet irons at a predetermined angle toward the outer surface of the rotor, and permanent magnets of different polarities received into the magnet receiving slots, wherein a magnetic flux leakage preventive groove having a predetermined width and depth is formed at the outer surface of the rotor at the center between the pair of magnet receiving slots.
