Abstract: An electric motor includes a rotor and a stator formed by a plurality of stator phases. The stator phases include coils that extend fully about the motor axis of the motor. The stator phases further includes flux rings disposed on opposite axial sides of the coil and that are joined by axial returns. The stator phases electromagnetically drive rotation of the rotor on the motor axis.

Abstract: A stator pole for a stator of a transverse flux machine is provided. The stator includes a stator winding arranged in a winding space, and the winding space being formed circumferentially in a circumferential direction in relation to an axis of rotation of a rotor. The stator pole has a body element made of a ferromagnetic material, which has at least one pole head which, in the installation position, may be arranged opposite the one rotor, and a magnetic return path region, which may be arranged facing away from the one rotor, wherein a number of the pole heads of the stator pole correspond to a number of the rotors. The stator pole is configured to occupy only a portion of a circumference of the winding space in the circumferential direction, and the magnetic return path region has a curved shape which adjoins the at least one pole head, as a result of which the magnetic return path region is designed to define the winding space in part transversely to the circumferential direction.

Abstract: A flux machine has plural coil assemblies and plural magnet sets arranged in mutual close proximity and circularly about a central axis. Either one of the coil assemblies and the magnet sets are supported by at least one axle which is aligned with the central axis, and either one of the coil assemblies and magnet sets executes rotary motion about the central axis when electrical current is present in the coil assemblies. Magnetic flux of the magnet sets is directed axially and radially while machine rotation is orthogonal to the direction of flux. A plurality of magnets in each magnet set are supported by one or another of a plurality of coaxially aligned axles so that the flux machine may operate as an electrical motor, as an electrical generator, or both at the same time.

Abstract: A transverse flux reciprocating motor and a reciprocating compressor having a transverse flux reciprocating motor are provided. The transverse flux reciprocating motor may include a stator wound with a magnet coil, a mover inserted into the stator and coupled with a magnet having opposite magnetic poles in an orthogonal direction with respect to a magnetic flux generated by the magnet coil, and a magnetic resonance spring that allows the mover to perform a resonance motion with respect to the stator using a force trying to move toward a side with low magnetic resistance between the stator and the mover, whereby the transverse flux reciprocating motor and the reciprocating compressor having a transverse flux reciprocating motor may be reduced in size and weight and obtain high efficiency.

Abstract: A transducer contains a rotor, on which permanent magnets are arranged in a concentrically radiant manner, and two stators are provided at both sides of the rotor. The stators are produced from a soft-magnetic material. Each stator contains a first stator section with radially outer supporting bars for first magnetic active faces of the stator being opposite the rotor and a second stator section with radial inner supporting bars for second magnetic active faces of the stators being opposite the rotor. An annular winding groove for receiving a winding is provided between the stator sections. Supporting bars are each arranged in an annular manner and each extend parallel to the rotor axis in the direction of the rotor. The magnetic active faces of the stators are end faces of projections which are uniformly spaced to one another and which protrude from the supporting bars in the direction of the rotor.
