Abstract: A direct-drive generator and assembly procedure for that generator include a permanent magnet assembly that is partitioned and assembled piece-by-piece after the rotor and stator have been attached.The magnets are attached to a plate in columns, and adjacent columns have a N-S orientation. The air gap between the rotor and stator is variable, and application of an input torque produces a first cogging torque in a first direction due to the variable air gap that offsets a second cogging torque in a second opposite direction.

Abstract: The invention is a generator and cooling mechanism. The generator includes a rotor comprising a shaft with a skewed alignment of magnets on a ring, a stator of toothed laminations with coils wound around the teeth, and a housing with cooling chambers. The housing has annular subchambers arranged successively along the length of the generator in such a way that cooling fluid must flow to the opposite side of the generator to pass into the next chamber. Because the housing is highly heat conductive, this structure of annular subchambers increases the uniformity of the fluid temperature.

Abstract: A permanent magnet included in a rotor of a brush-less motor is a radial anisotropic magnet in which multi-poles are magnetized in the circumferential direction and is skew magnetized along the axial direction in such a manner that a surface to one end part of an upper side from a central part in the axial direction and a surface to an end part of a lower side from the central part are axially shifted by a predetermined angle in the circumferential direction from each other. In accordance with this skew-magnetization, coggings including irregularly varying components generated in the rotor owing to the three-dimensional shapes of coil ends provided at opposite ends of a tooth 611a for fixing a winding have opposite phases to each other, so that the coggings are cancelled with each other. Accordingly, the coggings can be reduced or cancelled.

Abstract: Torque coupling systems and methods thereof include concentric cylindrical inner and outer rotor systems. The inner rotor system extends at least generally along the axis of the cylinder and comprises two or more inner magnets which have equal numbers of alternating positive poles and negative poles. The outer rotor system is seated over at least a portion of the inner rotor system and comprises two or more outer magnets which have equal numbers of alternating positive poles and negative poles. In the resting or stable position, the inner positive pole magnets are adjacent to the outer negative pole magnets. At least one of the two or more inner magnets and at least one of the two or more outer magnets have edges which are skewed around the first axis. The movement of the outer rotor system with respect to the inner rotor system applies a torque to a device coupled to the inner rotor system.

Abstract: 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.

Abstract: A wireless encoder system facilitates operation and control of a motor, such as linear motor. The system includes an encoder sensor moveable with a first part of the motor. The encoder sensor is operative to sense movement of the first part relative the second part and provide an encoder signal having an electrical characteristic indicative of the sensed movement. A transmitter, which is associated with the encoder sensor, is operative to transmit a wireless transmitter signal based on the encoder signal. A remote receiver that receives the wireless transmitter signal thus may determine position and/or movement of the first part of the motor relative to a second part of the motor.
