Described herein are fractional-slot-winding motors and electric vehicles using such fractional-slot-winding motors. In some examples, a fractional-slot-winding motor comprises a stator, a bus-bar assembly, and a plurality of coil units. The stator comprises a plurality of stator slots (e.g., 63 slots) extending through the core and radially offset relative to each other. Each dual-leg coil unit extends through two different stator slots and is electrically coupled to two other coil units on the coil-interconnection side of the rotor. Each single-leg coil unit extends through one coil slot and is electrically coupled to one other coil unit on the coil-interconnection side. At least some single-leg coil units can be coupled to a bus-bar assembly. Furthermore, the ends of the coil unit can have radial offsets relative to protruding portions, e.g., closer to the motor primary axis at the coil-interconnection side and further away on the opposite side.
