Abstract: Provided is a highly responsive linear motor that can be constructed by reducing the weight of a mover. In order to attain this object, the linear motor includes a secondary side in which magnets and ladder-shaped members of a magnetic material are arranged in alternate manner in a rectilinearly moving direction of the mover, the ladder-shaped members each holding one of the magnets; and a primary side that includes magnetic pole pieces arranged in close proximity to the secondary side from above and below in a direction perpendicular to the rectilinearly moving direction with a common coil wound around each of the magnetic pole pieces, the primary side including a magnetic material core interconnecting the magnetic pole pieces; wherein the ladder-shaped members of a magnetic material are formed with grooves.

Abstract: A rotor disk for an electric motor including a shaft hole for receiving a shaft of the electric motor, a set of positioning holes around the shaft hole, each configured to receive a positioning pin. The shaft hole and the set of positioning holes are positioned in the rotor disk such that when the rotor disk is set to a rotated position with respect to another similar rotor disk, and the shaft and the positioning pins are penetrated to the respective holes of the two rotor disks, the disks cause a pressing force to the shaft.

Abstract: Electrical machines, for example transverse flux machines and/or commutated flux machines, may be configured to achieve increased efficiency, increased output torque, and/or reduced operating losses via use of laminated materials, for example laminated materials configured with cuts and/or segmentations. Segmentations may also assist with manufacturability, mechanical retention of components, and the like.

Abstract: A reinforcement structure for a disc motor being received in the flat space formed at a side of a wheel center for driving the wheel to rotate as it can be activated to perform a rotation movement by the interactions of an electromagnetic field formed from its stators and a magnetic field resulting from its rotator, comprises: a rib structure, arranged inside a shell housing the disc-like stator for enhancing the structure integrity thereof without causing the thickness thereof to increase and thus maximizing the usefulness of the motor's limited space; and a fixing element, for fixing the stators to the inner side of the motor's outer shell for preventing the stators to be deformed by the magnetic force from the permanent magnets mounted on the rotors while preventing the stators from being attracted by the permanent magnets of the rotors, and thus enabling the motor to operate smoothly.

Abstract: An electric machine having a stator body and a machine housing is provided. The stator body includes a stator ring of generally annular shape and a plurality of stator teeth projecting radially inward. A first bolt hole is defined in either the stator ring or machine housing, and a first receptacle is defined in the other and is coaxial with the first bolt hole. A second bolt hole is defined in either the stator ring or machine housing, and a second receptacle is defined in the other and is coaxial with the second bolt hole. A first counter bore is coaxial with the first receptacle. A first hollow dowel is mated to the first counter bore and the first bolt hole, and defines a first dowel hole, which is coaxial with the first counter bore and the first bolt hole.

Abstract: A rotor for an electrical machine includes a first shaft part and a second shaft part, which is arranged separately from the first shaft part. A first supporting element is connected in a manner fixed against rotation to the first shaft part, and a second supporting element is connected in a manner fixed against rotation to the second shaft part. The rotor has a yoke which connects the first supporting element to the second supporting element and includes a plurality of laminates arranged one behind the other, and which has cutouts extending in the direction of the axis of rotation in the interior of the yoke, and permanent magnets arranged in the cutouts. The yoke has holes extending in the direction of the axis of rotation, with tensioning pins extending through the holes in the yoke to brace the laminates.

Abstract: A rotor core assembly for an electric motor includes a stack of laminations and first and second end plates disposed at opposite ends of the stack of laminations. A plurality of concentric fastener holes extend through the laminations and the end plates for receiving stainless steel pins. Each pin has a head against one of the end plates, and each pin has spaced apart grooves thereon extending from the other end plate. A stainless steel collar engages each of the pins and contacts one of the end plates. Each collar has a deformed portion in at least one of the grooves of the pin.

Abstract: The present invention relates to an axial motor, and more specifically, to an axial motor which has a simple structure and is easily assembled by inserting and holding core teeth in core teeth insertion holes circularly arranged on a yoke.
