Abstract

The invention provides a production method for a hub motor rotor with embedded radial permanent magnet steel and embedded tangential permanent magnet steel, and belongs to the technical field of automobile motors and electrical appliances. Rectangular permanent magnet steel is embedded in a radial rectangular groove and a second tangential rectangular groove of a rotor core respectively to form an embedded permanent magnet rotor. The structure is a rotor magnetic bypass structure, the problem that irreversible demagnetization happens to the permanent magnet steel under the action of armature reaction of impulse current can be effectively prevented, it is guaranteed that the permanent magnet steel does not lose magnetism, and meanwhile a hub drive motor rotor field is jointly provided by a radial magnetic field and a tangential magnetic field. Besides, the hub motor rotor with the embedded radial permanent magnet steel and the embedded tangential permanent magnet steel has the advantages that magnetic field intensity is high, output power is high, efficiency is high, power density is high, the structure is compact, and working is reliable.
