High performance air core motor-generator winding
InactiveUS7402934B1Long and reliable operating lifeIncrease winding densitySynchronous generatorsWindingsMagnetic polesRotational energy
A motor-generator for converting between electrical and rotational energy includes a rotor mounted for rotation about an axis of rotation relative to a stationary a stator that magnetically interacts with the rotor. The rotor has two spaced apart rotor portions that define therebetween an armature airgap. Magnetic poles on the rotor portions drive magnetic flux across the airgap. An air core armature is located in the airgap, such that opposite sides of the air core armature face the two opposed rotating surfaces of the rotor. The air core armature has windings in which AC voltage is induced as the rotor rotates. The windings are wound with multiple individually insulated strand conductor wire wrapped with a wrapping of a thin dielectric tape film over the multiple individually insulated strand conductor wire.

The winding of matrix transformers having multiple turn primary windings is made much easier, and the resulting transformer is much more consistent, if a “cellular” insert having a plurality of through holes is placed through each trough hole of the matrix transformer. Preferably, there is one hole in the cellular insert for each wire, though two or more wires can be placed in each hole. In one embodiment, insulating cellular inserts are placed through the entire length of the cellular transformer to guide and locate the primary windings. In another embodiment, each element of the cellular transformer has cellular inserts, and the elements are coupled together. In another embodiment, the cellular insert is a conductor and is part of the secondary circuit.

Method of magnetizing a ring-shaped magnet
InactiveUS6080352AAvoid missingLow costOther chemical processesInorganic material magnetismDetentMagnetization
A brushless permanent-magnet direct current motor has a permanent magnet which is magnetized to create an offset angle between detent and mutual torques for providing sufficient starting torque for all relative orientations between the stator and the rotor of the motor. This is accomplished by providing a permanent magnet in which the global magnetization of the magnet has been disrupted by the application of a local magnetic field to a portion of the magnet, thereby to provide a magnetic anomaly in the global magnetization. Also, a method of magnetization of the magnet is described.

It is an object of the present invention to make it possible to easily wind a stator winding, enhance an occupied ratio in a stator core, reduce a winding resistance because there is no coil end, and change a field magnetic flux in accordance with a use.Stator pawl magnetic poles of a stator core extend from both sides in an axial direction alternately at locations opposed to a rotor to form a plurality of magnetic poles. With this stator core, it is only necessary to annularly wind a stator winding. Therefore, it is possible to enhance operability and an occupied ratio, and since there is no coil end, it is possible to reduce winding resistance. Since the rotor is a Randall type rotor having a field winding and a rotor pawl magnetic pole, it is possible to change the field magnetic flux in accordance with a use.
