Abstract
A vehicle motor for a motor bicycle, which includes a wheel hub, a rotor, a stator, and a wheel axle, wherein the rotor includes a yoke ring fixedly mounted inside the wheel hub and a plurality of magnets equiangularly arranged inside the yoke ring; the stator includes a disk body fixedly mounted on the wheel axle and suspended inside the wheel hub within the rotor, and a silicon steel stack fixedly mounted around the periphery of the disk body, the silicon steel stack having a plurality T-teeth, the number of the T-teeth being not a common multiple of the number of the magnets so that vibration and cogging torque can be minimized during rotary motion of the rotor relative to the stator, and a three-phase winding mounted on the T-teeth of the silicon steel stack of the disk stator.
