摘要： A synchronous induction motor features improved assemblability of a rotor, significantly reduced production cost, and improved operation performance of the motor. A plurality of die-cast secondary conductors is provided around a rotor yoke constituting the rotor of the synchronous induction motor. End rings are die-cast integrally with the secondary conductors on the peripheral portions of both end surfaces of the rotor yoke. Permanent magnets are inserted into slots formed such that they penetrate the rotor yoke. The openings of both ends of the slots are closed by a pair of end surface members formed of a non-magnetic constituent. One of the end surface members is secured to the rotor yoke by one of the end rings when the secondary conductors and the end rings are formed. The other end surface member is secured to the rotor yoke by a fixture.

摘要： A brushless DC motor minimizes a chance of dislocation of or damage to an insulator used in the brushless DC motor. Slant portions are provided at end portions of the insulator; therefore, even if a nozzle of a machine for installing a winding should hit the insulator while moving between teeth, the insulator moves in a direction for coming in close contact with a slot aperture, i.e., in a direction substantially at right angles to a direction in which the nozzle moves. This arrangement prevents the insulator from moving by being pushed by the nozzle, making it possible to minimize a chance of occurrence of an insulation failure caused by a damaged or dislocated insulator.

摘要： A concentrated winding type brushless DC motor has a stator formed by a slack of laminations of a ferro-magnetic material having an outer ring from which a plurality of spaced teeth extend inwardly and have slots between adjacent teeth. A drive coil is wound around each tooth in the presence of a spacer provided between an end surface of a stator tooth and the drive coil to reduce stress applied to a tooth by the coil as it is being wound. The final form of the motor has the spacer removed leaving a space between the coil and the tooth to form a magnetic pole of the stator.

摘要： A stator core for a concentrated winding type brushless DC motor that has a plurality of spaced teeth extending inwardly of the core outer diameter to a core inner diameter to define slots between two adjacent teeth for a winding. Each tooth has right and left distal ends projecting in opposite directions transverse to the tooth with the opposite distal ends of two adjacent teeth each being linear and defining an aperture into a slot between the two teeth. The distal end of each tooth also has an angled edge at the side facing the core outer diameter so that the distal end is wider at the aperture than at the point where the distal end extends from the tooth. Also, there is a distance T between a line connnecting the end points of the right and left distal ends of a tooth facing the core outer diameter at the aperture defined by each said distal end and a tangent line at an inner core diameter of the tooth and such that T≧0.

摘要： DC power is supplied to an induction motor for a compressor by switching ON/OFF in response to a modulated voltage waveform obtained from modulating waves which are used for generating AC power for energizing an induction motor and a carrier wave according to PWM theory. The compressor has a compressing element rotated by the induction motor, and the modulating wave is corrected according to a rotational angle of the compressing element. A sine wave having the same frequency as the modulating wave is added to the modulating wave, and a phase of the sine wave is controlled so that a maximum value of the sine wave corresponds to the compression stage of the compressing element. Thus, a rotation speed of the compressing element is constant in a suction stage and a compression stage.
