Abstract
The present invention relates to a toroidal motor in which a coil is wound around a yoke, and more particularly, to a toroidal motor in which a process of winding a coil starts from an inside of a yoke to ensure a sufficient insulation distance from a rotor side housing, a busbar assembly is disposed on an upper portion of the yoke to make it easy to connect a busbar and the coil, and the busbar is configured so as not to cover a slot, through which cooling air flows, to ensure cooling performance and simplify an entire structure of the motor.
Claims9
A toroidal motor comprising:
- an annular yoke;
- a plurality of teeth protruding radially from the yoke and spaced apart from one another in a circumferential direction of the yoke;
- coils disposed between two adjacent teeth among the plurality of teeth and wound around the yoke,
- a busbar assembly electrically connected to the coils,
- wherein a tip portion of each of the coils from which a process of winding the coil starts is positioned radially inside the yoke,
- wherein a distal end portion of each of the coils at which the process of winding the coil ends is positioned radially outside the yoke,
- wherein the tip portion of each of the coils is positioned adjacent to a radially inner surface of the yoke, the distal end portion of each of the coils is positioned to be spaced apart from a radially outer surface of the yoke,
- wherein the tip portion of each of the coils is positioned adjacent to any one of the two teeth positioned at two opposite sides of each of the coils,
- wherein the distal end portion of each of the coils is positioned adjacent to the other of the two teeth,
- wherein the busbar assembly comprises:
- an annular assembly body;
- and
- a plurality of busbars protruding radially from the assembly body, and
- wherein the assembly body and the yoke are disposed side by side in an axial direction.
