Description
Technical field
The present invention relates to motor field more particularly to a kind of rotor structures of bimorph transducer folder center roller magneto.
Background technique
Many motor application application requirements motors have the function of that quick response, torque density are high, torque pulsation is small.It is existing
Many motors can not meet this demand simultaneously.There is following more formidable disadvantage in existing magneto:
First, existing bimorph transducer presss from both sides in center roller magneto, and permanent magnet is not made into cylinder, so embedded tile
The rotor of shape permanent magnet is bigger than the rotor volume of embedded permanent magnet, is equally circular ring shape rotor structure in terms of quick response, interior
The rotor structure of the permanent magnet of embedding tile shape is good not as good as the rotor structure performance of embedded permanent magnet.
Second, permanent magnet is made into tile shape by existing magneto, the permanent magnet of tile shape relative to permanent magnet volume more
Greatly, the number for the tile shape permanent magnet being embedded in using the permanent magnet of same volume is fewer than permanent magnet number, the number of magnetic poles of permanent magnet
Few torque density is low.
Permanent magnet is made into tile shape or similar tile shape by third, existing magneto, the permanent magnet of tile shape relative to
Permanent magnet is unable to fully cause the waste on permanent magnet material using material.
4th, existing bimorph transducer presss from both sides in center roller magneto, and there are interelectrode magnetic leakage phenomenons for tile shape permanent magnet.
Summary of the invention
In order to solve the above technical problems, the invention patent provides the following technical solutions: a kind of bimorph transducer folder center roller is forever
The rotor structure of magneto, including rotor core, permanent magnet, auxiliary tank, end cap, shaft, circumferentially side in the rotor core
To permanent magnet is equidistantly placed with, it is equipped with auxiliary tank between the adjacent permanent magnet, the auxiliary tank is along the circumferential direction equally spaced
Auxiliary tank number on the inside of the inner side and outer side of rotor core, the rotor core is equal to the auxiliary tank on the outside of rotor core
Number, the end of the rotor core are equipped with end cap, and the center point of the end cap is equipped with shaft.
In above-mentioned technical proposal, the rotor core is overrided to form by the non-oriented silicon steel sheet of 0.2mm thickness.
In above-mentioned technical proposal, the rotor core is circular ring shape.
In above-mentioned technical proposal, the permanent magnet is cylindrical.
In above-mentioned technical proposal, the permanent magnet material uses neodymium iron boron.
In above-mentioned technical proposal, the sum of the number of the auxiliary tank is 2 times of permanent magnet number.
By using above-mentioned technical solution, the beneficial effect of the invention patent is: in the permanent magnet using same volume
In the case where, the circumferentially equally distributed permanent magnet is more than tile shape permanent magnet, improves the number of poles of rotor, no
It only can accomplish quick response and improve the torque density of motor, and be made using the rotor structure of permanent magnet ratio
It is small with the rotor structure cogging torque of tile shape permanent magnet, equally distributed auxiliary tank is provided in the rotor core, rationally
The size of setting auxiliary tank can mitigate the weight of rotor while reducing torque pulsation.

Specific embodiment
Technical solution of the present invention is described in further detail below in conjunction with Figure of description.
Fig. 1 is the rotor structure that a kind of bimorph transducer presss from both sides center roller magneto, comprising: rotor core 1, permanent magnet 2 are auxiliary
Help slot 3, end cap 4, shaft 5.
It is along the circumferential direction equidistantly placed with permanent magnet 2 in the rotor core 1, is equipped between the adjacent permanent magnet 2 auxiliary
Slot 3 is helped, the auxiliary tank 3 is along the circumferential direction equally distributed on the inner side and outer side of rotor core 1.
3 numbers of auxiliary tank of 1 inside of rotor core are equal to 3 numbers of auxiliary tank in 1 outside of rotor core, the rotor
The end of iron core 1 is equipped with end cap 4, and the center point of the end cap 4 is equipped with shaft 5.
In this way of example, the rotor core 1 is overrided to form by the non-oriented silicon steel sheet of 0.2mm thickness, can be subtracted
Few motor iron loss, improves electric efficiency.
In this way of example, the rotor core 1 is circular ring shape, reduces motor starting time.
In this way of example, the permanent magnet 2 is cylindrical, the case where using the rare earth permanent-magnetic material of same volume
Under, the number for the permanent magnet 2 that the rotor structure circumferentially embeds is more than the number of embedded tile shape permanent magnet 7, increases
Add the number of pole-pairs of motor, motor can achieve the purpose that quick response with quick start, motor during rotation it is described forever
Magnet 2 can be better relative to the tile shape permanent magnet 7 of the rotor structure of the folder center roller motor of tradition bimorph transducer shown in Fig. 2
Optimize magnetic circuit, allow main flux on set magnetic circuit, not only reduces the slot leakage of motor, interelectrode magnetic leakage can also reduce tooth socket and turn
Square.
In this way of example, 2 material of permanent magnet uses neodymium iron boron, and the magnetic energy product of NdFeB material is high, improves electricity
The torque density of machine.
In this way of example, the sum of the number of the auxiliary tank 4 is 2 times of permanent magnet number, and the auxiliary tank 4 is pressing down
It can reduce torque pulsation while harmonic wave processed.
The above is only a preferred embodiment of the present invention, protection scope of the present invention is not limited merely to above-mentioned implementation
Example, all technical solutions belonged under thinking of the present invention all belong to the scope of protection of the present invention.It should be pointed out that for the art
Those of ordinary skill for, all within the spirits and principles of the present invention, it is made it is any modification, retouching etc., should all include
