Description

technical field [0001] The invention relates to the field of motor manufacturing, in particular to a radial flux motor. Background technique [0002] The work of traditional motors is mainly designed by the principle of force on the current-carrying conductor in the magnetic field. The magnitude of the force is: F=BIL (Note: F is the force, the magnetic flux is B, the current is I, and the length of the conductor is L) . The current-carrying conductor of the traditional motor is an enameled wire, and the total torque generated is: T=Z2rBILsinα (Note: the torque is T, the effective side length of the coil is r, and the total number of turns of the coil is Z). [0003] Therefore, the traditional motor has large volume, low efficiency, high cost and many materials. In many fields, especially in new energy electric vehicle driving motors, the requirements are high, which leads to great limitations in product selection. Generally, the weight and volume of the motor are reduced...
