Rotor Having Magnet Structure of Hybrid Type, High Power Motor and Water Pump Using the Same

摘要

The invention of a number of inexpensive ring-shaped magnet and isotropic state the price side of the magnet and magnetic yibangseok it is possible to implement a low cost, and the magnetic force of the rotor as a whole by combining, it relates to a high efficiency by using the hybrid that can be configured for a high output motor (hybrid) a rotor having a magnet structure of the method, high-output motor and the water pump using the same. . The rotor of the present invention is coupled to the rotating shaft center part, a plurality of grooves are formed at regular intervals on the outer peripheral surface, and a back yoke which form a magnetic circuit of the Cylinder-shaped; And a plurality of outer secondary magnet disposed a plurality of grooves formed in the back yoke; Characterized in that the inner periphery to the outer periphery of the back yoke is made of a ring-shaped bonded magnet comprising a plurality of number of accessories with the same number of the main magnet is magnetized so as to have divided the number of pole. A rotor having a magnetic structure of the hybrid type with an inner rotor or outer rotor and the stator can be configured by combining a high-output motor, the motor may be configured by using a water pump. ;
