Abstract

The invention provides a tangential and radial resultant magnetic field embedded permanent magnet rotor driving motor, and belongs to the technical field of automobile motor electric appliances. The tangential and radial resultant magnetic field embedded permanent magnet rotor driving motor is composed of a front end cover, a rear end cover, a shell, a rotor and a stator. Pieces of rectangular permanent magnet steel are embedded into tangential rectangular grooves and radial rectangular grooves of a rotor iron core respectively. Due to the fact that the tangential and radial resultant magnetic field embedded permanent magnet rotor driving motor is of a rotor magnetic bypass structure, the problem that irreversible demagnetization is generated when the permanent magnet steel bears excessively-high temperature or the action of the armature reaction of an impact current can be effectively avoided, it is ensured that demagnetization does not happen on the permanent magnet steel, the magnetic field of the rotor of the driving motor is supplied by both the tangential magnetic field and the radial magnetic field, the magnetic field intensity is large, output power is high, an electro-magnetic winding is not required, power consumption is little, a carbon brush and a mechanical diverter are omitted, the failure rate is low, and the tangential and radial resultant magnetic field embedded permanent magnet rotor driving motor has the advantages of being high in efficiency and power density, compact in structure, reliable in work and the like.
