Hub driving motor equipped with built-in permanent magnet steels and used for electric vehicle

The invention provides a hub driving motor equipped with built-in permanent magnet steels and used for an electric vehicle, and belongs to the technical field of motors and electric appliances of electric vehicles. The driving motor comprises a front end cover, a back end cover, a hub type machine case, a rotor and a stator, wherein rectangular permanent magnet steels are embedded in corresponding first rectangular grooves and second rectangular grooves of the rotor iron core respectively; the magnetic field of the rotor of the hub driving motor is jointly supplied by dual-radial magnetic fields, so that high magnetic field strength and high power density are realized; and in addition, the hub driving motor is free of an electric excitation winding, low in electric energy consumption, free of a carbon brush and a mechanical commutator, low in fault rate, high in efficiency, compact in structure, reliable in operation and the like.
