The invention discloses a magnetizing head for a motor, and a magnetizing device with the magnetizing head. The magnetizing head is suitable for being inserted in a magnetic ring of the motor to magnetize the magnet ring, the magnetizing head comprises an annular iron core, the iron core comprises a plurality of iron core teeth, inner ends of two connected iron core teeth are connected to each other, and the outer ends are separated from each other; and a winding, wherein the winding comprises a plurality of pole windings, and the plurality of pole windings are winded on the plurality of ironcore teeth in a one-to-one correspondence manner and are insulated from the iron core teeth. The volume of the magnetizing head for the motor according to the embodiment of the invention is smaller, the magnetizing head can perform magnetization from inside to outside through the magnetic ring, the assembly of the magnetic ring is facilitated, the winding of the magnetizing head is simpler, the groove fullness rate is higher, and the magnetizing effect is better.
Description
technical field [0001] The present invention relates to the technical field of magnetizing equipment, and more particularly, to a magnetizing head for a motor and a magnetizing equipment having the same. Background technique [0002] Due to its simple structure, external rotor motors are widely used in various small home appliance industries, especially in the fields of relatively small power home appliances such as small desk fans, small fans, heaters, and low-power purifiers. With the requirement of cost pressure for external rotor motors, more and more annular magnetic strips are used. The multi-pole magnetization technology of annular magnetic strips is relatively complicated. At present, the magnetization method generally adopts the method of first filling the magnets and then assembling, and the process is complicated. . Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore...
