Abstract
The utility model discloses a permanent-magnet machine, comprising a rotor which is composed of a rotary shaft, a rotor block and magnetic steel. The contact face of the magnetic steel and the rotor block is a mutual matching concave-convex structure. The design goal of the permanent-magnet machine of the utility model is implemented in this way: the contact face of the magnetic steel and the rotor block is the mutual matching concave-convex structure, the magnetic steel transfers the electromagnetic force moment to the rotor block by the concave-convex structure, and the electromagnetic force moment is transferred to the rotary shaft by the rotor block to obtain the output of the force moment. Thus, the junction surface of the surrounding of the rotor block is not needed to be adhered, the disadvantage that rare earth magnetic steel can not be disassembled, recovered and used in the prior art is solved, and the cost of the permanent-magnet machine is reduced.
Description
Technical field
The utility model relates to a kind of magneto.Specifically, relate to a kind of magneto of making magnet steel with rare earth material.
Background technology
Present magneto, its rotor magnetic steel all adopt bonding or interference fit, can't dismantle and utilize.General at large-scale magneto, as the magneto of multikilowatt, magnet steel adopts rare earth material to make.Rare earth material costs an arm and a leg, and in the multikilowatt motor, the rare earth material consumption is big in addition, thereby large-scale magneto cost is very high.If can recycle, be the effective ways that reduce cost.
Summary of the invention
The goal of the invention of the utility model magneto is to overcome above-mentioned deficiency, the magneto that provides a kind of magnet steel dismounting that rare earth material can be made to recycle.
For achieving the above object, the utility model magneto comprises rotor, and rotor is made up of rotating shaft, rotor block, magnet steel, and magnet steel and rotor block contact-making surface are the concaveconvex structure that cooperatively interacts.
The goal of the invention of the utility model magneto is achieved in that magnet steel and rotor block contact-making surface are the concaveconvex structure that cooperatively interacts, and magnet steel passes to rotor block by this concaveconvex structure with electromagnetic torque, and rotor block passes to rotating shaft, reaches moment output.Thereby the faying face around the rotor block is bonding with regard to no longer needing to carry out, and has solved in the prior art, and rare earth magnetic steel can not be dismantled the shortcoming of recycling, has reduced the cost of magneto.
Description of drawings
Fig. 1 is a kind of embodiment rotor of the utility model magneto;
Among the figure, 1-rotor 2-rotating shaft 3-rotor block 4-magnet steel 5-contact-making surface 6-concaveconvex structure.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model earth rod is described in further detail and describes.
Fig. 1 is a kind of embodiment of the utility model magneto.Among the figure, the utility model magneto comprises rotor 1, and rotor 1 is made up of rotating shaft 2, rotor block 3, magnet steel 4, magnet steel 4 and the concaveconvex structure 6 of rotor block 3 contact-making surfaces 5 for cooperatively interacting.
Magnet steel 4 and the concaveconvex structure 6 of rotor block 3 contact-making surfaces 5 for cooperatively interacting, magnet steel 4 passes to rotor block 3 by this concaveconvex structure 6 with electromagnetic torque, and rotor block 3 passes to rotating shaft 2, reaches moment output.Thereby the faying face 5 around rotor block 3 is bonding with regard to no longer needing to carry out, and has solved in the prior art, and rare earth magnetic steel can not be dismantled the shortcoming of recycling, has reduced the cost of magneto.
The utility model is not limited to the scope of embodiment, and all innovation and creation that utilize the utility model design are all at the row of protection.
