A motor integrated type fluid machine suctions a fluid from a suction port and discharges the suctioned fluid from a discharge outlet. The machine includes: a shaft portion provided at a center of a rotation axis; a rotating portion rotating around the shaft portion; an outer peripheral portion provided on an outer periphery of the shaft portion; and an outer peripheral drive motor rotating the rotating portion. The rotating portion includes a hub rotatably supported by the shaft portion, blades provided on an outer peripheral side of the hub and provided side by side in a circumferential direction of the rotation axis, and a rotating outer peripheral portion having an annular shape along the circumferential direction. A ratio of a rigidity of the rotating outer peripheral portion against a centrifugal force to a rigidity of the rotating portion against the centrifugal force is 50% to 95%.

An electric-powered vehicle includes: an axle body that includes an axle and drive wheels connected to both ends of the axle; a magnetic geared motor for rotating the axle, the magnetic geared motor including a stator, a low-speed rotor, and a high-speed rotor; a vehicle structure supported by the axle body; a motor support for connecting the vehicle structure and the stator, and supporting the magnetic geared motor by the vehicle structure; and an elastic coupling for coupling the low-speed rotor and the axle such that a rotational force of the low-speed rotor is transmittable to the axle.

A linear fan including a fan blade attached a fan frame by a wire spring having a first end attached to the fan blade and a second end attached to the fan frame. The fan blade includes a free end such that the blade oscillates by pivoting on the wire spring. The the wire spring flexes to enable the fan blade to oscillate. The fan includes a motor for driving the oscillation of the fan blade. The motor includes an armature or permanent magnet connected to the fan blade and a stator assembly connected to the fan frame. The stator assembly includes a current carrying coil wrapped around a leg of a stator core. The motor is controlled to vary the direction of the current being carried in the coil to thereby change the direction of the magnetic field created by the stator assembly and cause the fan blade to oscillate.

An electric machine, including a housing, a rotor which includes a rotor shaft and a rotor laminated core, a directly cooled stator which includes a stator laminated core, an annular gap configured between the rotor laminated core and the stator laminated core, and a sleeve-like wall element disposed in the annular gap, wherein the wall element abuts the stator with its outer surface and seals the stator against the rotor, wherein the housing is configured in a pot-like manner such that it is permanently or tightly closed on a first axial side by a bottom wall at least radially overlapping the stator and is open on an opposite second axial side and can be closed there via a lid, and a seal is disposed in a region of each axial end or each axial side of the wall element.

A stator arrangement for an electric engine having an inner rotor. The present invention furthermore relates to an electric engine for a charging device, in particular for an internal combustion engine or a fuel cell, having such a stator arrangement. The stator arrangement comprises an outer stator core with electrical windings, and a separate inner stator core, which is arranged inside the outer stator core and is designed to receive the rotor. The outer stator core defines a first inner diameter, which is dimensioned in such a way that a bearing unit of the electric engine can be guided through the outer stator core. An outer diameter of the inner stator core substantially corresponds to the first inner diameter, wherein the inner stator core is designed to extend a magnetic flux in the radial direction during operation. The invention furthermore relates to a method for producing the electric engine.
