The rotating electrical machine includes further an electrically conducting member having a hole, the electrically conducting member being attached to the frame such that the shaft extends through the hole.

An electrical distribution member includes a plurality of electrical conducting wires made of a solid wire. The electrical conducting wires each include an electrical conducting body, and a coating layer provided over a surface of that electrical conducting body, while removed therefrom over a respective predetermined length including a joining portion. The electrical conducting wires include at least one first electrical conducting wire having a joining portion extending in an axial direction of a stator core, and at least one second electrical conducting wire having a joining portion bent in relation to a radial direction of the stator core in such a manner as to follow a circumferential direction of the stator core. The predetermined length of the second electrical conducting wire with the coating layer removed therefrom is longer than the predetermined length of the first electrical conducting wire with the coating layer removed therefrom.

A method of forming an electrical motor, generator or other electromagnetic device by 3-D printing, wherein layers e.g. 24c-24s are successively deposited which comprise conductive regions and regions of a laminated, core, yoke or other former (11), so as to build up a plurality of conductors (12) extending inside spaces (26) in the former (11). The conductors (12) are interconnected at their ends to form a winding-like structure in or around the former (11) or a part thereof. The method enables each space (26) available in the former (11) to be filled with conductors (12), thereby maximising the efficiency of the device.

A stator of an electric motor having a stator core with a plurality of salient stator poles, an insulating cap, a stator winding consisting of a winding wire, and an interconnection unit with a plurality of winding-wire receptacles having an inside, wherein the winding wire is surrounded by a material constituting the winding-wire receptacle and connected and welded thereto on the inside. The stator is of an electric motor which is of a very high quality and precision so that high-current applications are possible. Without any major adjustments, the stator is combinable with different winding connections and is flexibly adaptable to the rest of the motor and possibly to the electronics design. The manufacturing method is capable of being flexibly adapted to different wire diameters.

A stator unit for including a plurality of coils includes a stator core configured to have the coils wound around the stator core; and a routing member including a plurality of groove configured to have wires routed in the groove, the wires extending from the coils.

A method for bonding electrical conductors is provided that is capable of suppressing a power source capacity when assembling a stator having a specific structure. First, coil pieces 9 are arranged in contact with bonding portions of a slot coil 5 inserted in a slot of a stator iron core 2 via a metal paste. Subsequently, an electrical current is applied using a pair of electrodes 11A and 11B in the axial direction (upward and downward in the figures) of the slot coil 5 while contact portions 15 between the slot coil 5 and the coil pieces 9 are pressed in an axial direction of the slot coil 5. As a result, electricity flows in the axial direction the coil piece 9 (a direction of an arrow X in the figures).

A micro fan is provided. The micro fan includes a rotor and a stator. The stator includes an axial induced coil unit and a circuit board. The axial induced coil unit is made by twining a coil in an axial direction for at least two layers and in a radial direction for at least two layers.

A connection portion between a conductive member and a coil end of the coil is arranged in an inter-pole gap between the magnetic poles. The rotary electric machine may include a rotor and a stator. The magnetic poles may be magnetic poles of the stator.

A stator includes an insulator, a wire, a stator core, a cylindrical hollow terminal through which the stator is to be electrically connected, and a resinous molding material covering the stator core and an outer face of the hollow terminal. An inner face of the hollow terminal is exposed from the molding material, and a first end of the hollow terminal is open to the outside of the molding material.
