Optionally, number N=6 of the magnet steel separator form 6 magnet steel slots.
Further, the connector is set as 12, wherein 6 locations of root are opposite with the position of the magnet steel separator
It answers.
The second aspect of the utility model provides a kind of magneto, including rotor, peace in the shell of the rotor
Equipped with magnet steel fixed frame as described above, and the magnet steel of rotor is placed in the magnet steel slot.
The utility model has the beneficial effects that
The magnet steel fixed frame of the utility model, structure is simple, and manufacturing cost is low, is designed using open type, very convenient patch
Magnet steel, and index accurately, effectively increase magnet steel installation effectiveness.Meanwhile the connector between inner ring body and outer ring body
Axial wind is generated when rotating at high speed, is equivalent to radiator fan, there are enormous benefits to motor radiating, and magnet steel is also not easy to move back
Magnetic can effectively improve the efficiency output and service life of motor.
