    Abstract: The stator laminations for a dynamoelectric machine may be first stacked in a concentric orientation and then skewed in a controlled manner after the stator is wound, with a pair of elliptically shaped alignment slots in each lamination holding a pair of alignment bolts of generally circular cross-section, such that the laminations may be first stacked onto the alignment bolts and then skewed by pivoting the alignment bolts, thereby causing relative radial movement between the laminations and the bolts as the bolts are permitted to slide within the elliptical alignment slots. In a second embodiment, a pair of radial projections on the stator laminations and a pair of channel members which surround the radial projections permit relative radial movement and canting of the projections with respect to the channel member as the channel members are pivoted to skew the stator lamination stack.

    Abstract: A rotor assembly for a permanent magnet motor includes a set of laminations forming a rotor body, each lamination having a first magnet slot therein. A generally rectangular permanent magnet is disposed in the magnet slot, the magnet slot of each lamination being shaped so as to receive the rectangular permanent magnet through all the skewed laminations with a minimum air gap. A method of making an assembly such as a rotor includes the steps of providing an assembly body made of ferromagnetic material defining at least one magnet slot therein. The slot is at least partially filled with a mixture of magnetizable particles in a binder. The mixture is compressed and then cured, to bond the magnetizable particles together in the slot, and the bonded particles are then magnetized in the slot to form a magnet in situ in the slot without an air gap.

    Abstract: A disk-type single-phase brushless motor wherein a reluctance torque having a sufficient magnitude can be generated to assure self-starting and continued rotation of the motor and production of disagreeable noises is minimized. The motor comprises a stator yoke mounted in an opposing relationship to a magnet rotor with an axial air gap left therebetween. The magnet rotor has an equal circumferential pole width .theta.. The stator yoke has a cutaway portion formed therein for enabling self-starting of the motor. The cutaway portion has a specific shape including a first radially extending edge and a second edge extending in a predetermined angular relationship from an inner end of the first edge to an outer circumferential edge of the stator yoke. The stator yoke is positioned at a predetermined angular position relative to a coreless armature coil so that the first edge thereof may be angularly spaced by a predetermined angle from a position at which a maximum starting torque is produced in the direction opposite the direction of rotation of the rotor.

    Abstract: When an induction motor is speed-controlled with a variable frequency power supply including thyristor inverters, operating loss due to harmonics components is increased in a rotor of the induction motor. In order to diverge additional operating loss into an appreciable depth of the rotor to thereby suppress the increase in the operating loss, the rotor comprises a cylindrical member having a circumferential resistivity which is larger than axial and radial resistivities and circumferential permeability which is smaller than axial and radial permeabilities, and a core disposed in the cylindrical member and having an axial permeability which is smaller than circumferential and radial permeabilities.
