摘要： 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.

摘要： Provided is a motor including a shaft; two rotors attached to the shaft and spaced from each other in an axial direction by a predetermined distance; a stator arranged between the two rotors; a busbar unit arranged on one axial side of at least one of the two rotors, and arranged to hold a busbar; and a housing arranged to hold the stator and house the two rotors therein. The stator includes a plurality of cores arranged in a circumferential direction, and coils wound around the cores. A lead wire drawn out from the coils is arranged to extend, radially outside of the one of the rotors, from the corresponding core to a position on the one axial side of the one of the rotors, and is connected to the busbar at the position. The busbar unit is housed in the housing.
