The utility model has the characteristics of construct simply, fixed firm, resistant demagnetization can the reinforce, and the cost is lower etc.
Description
Technical field
The utility model relates to field of electromechanical technology, particularly spoke type magnetic steel embedded motor rotor.
Background technology
Permanent-magnetic DC brushless motor rotor magnet steel is all generally tile shape, and tile shape magnet steel generally all adopts surface mount mode, also needs to add a protective jacket outside magnet steel.There is number of drawbacks in such mode: 1, magnet steel is tile shape, can increase the consumption of magnetic steel material, and significantly appreciating of current NdFeB material must cause the significantly rising of the overall cost of motor; 2, magnetic shoe is bonded at the outside of rotor core or is injection-moulded in the cylindrical of rotor, there is easy degaussing and the shortcoming of easily come off (sticky magnetic shoe structure); 3, rotor can produce larger centrifugal force when running up, and in order to prevent the coming off except the outside of the external magnet steel with quality glue will add protective jacket of magnetic shoe, same this measure also can increase material cost and the manufacturing cost of motor.
Summary of the invention
For the problems referred to above, it is simple that the purpose of this utility model is to provide a kind of structure, fixed, and resistance to demagnetization capability is strong, lower-cost spoke type magnetic steel embedded motor rotor.
Realize the technical solution of the utility model as follows:
Spoke type magnetic steel embedded motor rotor, comprise rotating shaft, rotor core and magnet steel, described rotor core is provided with centre bore, rotating shaft is sheathed in centre bore, rotor core is provided with multiple slotted eye, slotted eye is with the axle center of rotor core for center of circle circle distribution equably, and magnet steel is arranged in slotted eye, and described magnet steel is rectangular configuration.
Have employed above-mentioned scheme, magnetic shoe is designed to the magnet steel of cuboid, be embedded in spoke-type in rotor core, rotor core is that the riveted joint of silicon steel rotor punching forms, then the magnet steel of cuboid is embedded in rotor core, such magnet steel position is fixing reliable, can prevent motor magnet steel when running up from coming off; Non-ferromagnetic material can be used to reach the volume of ferromagnetic motor by the method for the concentration magnetic line of force; Number of poles is more, and magnet steel is thicker, and resistance to demagnetization capability is strong; Additionally use non-ferromagnetic material (as ferrite) in addition, cost is low.
Slotted eye and the perpendicular setting of rotating shaft, slotted eye is set to the rectangular shaped slot adapted with magnet steel, and these slotted eye two ends extend on two end faces of rotor core.
Slotted eye upper end is provided with the spacing block set be connected on rotor core exterior surface, and the lower end of slotted eye is provided with the support level be connected on rotor core inwall, and advantage is convenient to magnet steel install, fixing.
There is mesopore between magnet steel lower end and rotor core, advantage is convenient to heat radiation.
The end face of rotor core is provided with louvre, is convenient to motor radiating.
The outer surface of rotor core and two ends are coated with epoxy glue, are fixed in slotted eye by epoxy glue by magnet steel, advantage is sound construction, reduces costs.
