A driver of an automatic guided vehicle includes a crown gear (turning gear) fixed to a bottom of a vehicle body, a support shaft penetrating a center of the crown gear and extending vertically from the vehicle body, a frame supported by the support shaft to be rotatable on a horizontal plane, a wheel axle rotatably and horizontally provided on the frame, and a wheel connected to the wheel axle. A first motor and a second motor, which are drive sources, and a first planetary gear mechanism and a second planetary gear mechanism are provided at both ends in an axial direction of the wheel axle, respectively. Each carrier of the first and second planetary gear mechanisms is connected to the wheel axle, and each ring gear of the first and second planetary gear mechanisms meshes with the crown gear.

Driver of automatic guided vehicle

A motor assembly includes a motor, a speed reducer attached to one axial end of the motor, and an oil feeder between the motor and the speed reducer. The oil feeder is made of a material having elasticity and capable of storing a lubricating substance. The oil feeder includes a first lubrication portion that lubricates a gear of the speed reducer and a second lubrication portion that lubricates a bearing of the speed reducer.

Motor assembly

Embodiments of the disclosure provide an axial flux motor and an electrical product. The motor includes a rotor which rotates with a central axis as a center, and a stator which is disposed opposite to the rotor in an axial direction and has a plurality of stator units, the plurality of stator units being disposed around the central axis. The stator unit includes a core unit formed by a core piece, and a coil unit formed by a wire wound and disposed around the core unit. A height of the core unit in the axial direction is less than or equal to a height of the coil unit in the axial direction. With the embodiments of the disclosure, the dependency between the coil and the core in design and manufacture can be reduced, and the degree of design freedom can be improved.

Axial flux motor and electrical product

Embodiments of this application provide a stator element, a stator assembly, a motor, and an electromechanical device, the stator element including at least two stacked stator housing sheets, each of the stator housing sheets being a frame enclosed by a sheet periphery, at least two protrusions being disposed around the periphery of each of the stator housing sheets, the protrusion being directed from an inside of the stator housing sheet to an outside of the stator housing sheet, a groove being formed between adjacent protrusions, and protrusions of the adjacent stator housing sheets being alternately arranged in a direction in which the at least two stator housing sheets are stacked. Therefore, heat of a stator disposed inside the stator element can be dissipated with a strong heat dissipation capability at relatively low costs.

Stator element, stator assembly, motor, and electromechanical device

A motor includes a rotor including a rotating shaft, a nonmagnetic rotary frame, yokes arranged separately in the nonmagnetic rotary frame, and magnets arranged on surfaces of the yokes at least on one side of the yokes. To hold the yokes and the magnets, the nonmagnetic rotary frame includes a first annular rib that extends along a circumferential direction on a radially outer side of the rotating shaft, radially extending ribs that extend from a radially outer side of the first annular rib along radial directions, and a second annular rib joined to the radially extending ribs and concentric with the first annular rib.

Rotor and motor including the rotor

A power unit comprises: a wave gear speed reducer, a rotary shaft extending in the axial direction; a rotor unit that rotates integrally with the rotary shaft; a stator unit disposed facing the rotor unit; and a motor casing to which the stator unit is secured. The motor casing has a second cover that covers the rotor unit and the stator unit from the other side in the axial direction. The rotary shaft extends toward the other side in the axial direction, penetrates the second cover, and is connected to a cam. The second cover has a support part that extends toward the other side in the axial direction, supports the rotary shaft in a rotatable manner, and is positioned in a flexible cylindrical part of an external gear.
