Description
Technical field
The utility model relates to technical field of motors, relates in particular to a kind of magneto.
Background technology
At present, the technology of direct current or alternating current machine is very ripe, and principle all is to make rotor rotation and work done through magnetic induction.Yet, it is believed that the use of electricity still exists the space that can save, thereby just set about from the use of magnetic, hope to save the more energy through the use of magnetic.Like this; Utilize suction and the repulsion of permanent magnet or magneto that magnetic force is designed for actuating force just to arise at the historic moment; Up to the present; The disclosure of magneto technology is existing a lot, and its technological characteristics mostly are to utilize suction and repulsion or the magnetic force of permanent magnet as power, drive the rotation of rotor.
Magneto comprises rotor and stator mostly.Be placed with a large amount of magnetic links on the rotor, stator is provided with magnet exciting coil.The magnetic force that magnet exciting coil produces and the magnetic force of magnetic links itself produce active force, and then realize the rotation of rotor.Magneto has that cost is low, energy consumption is little, simple in structure, characteristics such as failure rate is low.At aspect of performance, can realize the performance of synchronous machine, asynchronous machine, stepping motor, can replace above-mentioned various motors.But there is the stator tooth effect of grooves in existing magneto, between stator, rotor, has location torque, and the existence of location torque not only makes rotor can only be still on a certain position with respect to stator; And when electric motor starting, produce a very big staring torque, in the magneto rotation process, very big vibration appears easily; Rotate unsmooth; Thereby cause vibrating noise, decrease in efficiency, even cause magneto to repair.
The utility model content
The purpose of the utility model is to provide a kind of skewed stator slot formula magneto, to solve the problems of the technologies described above.
The technical problem that the utility model solved can adopt following technical scheme to realize:
Skewed stator slot formula magneto comprises a motor housing, is provided with stator in the said motor housing; Said stator is provided with the wound core that is used to twine magnet exciting coil, in the said bore of stator rotor is housed, and is fixed with magnetic links on the said rotor; Said wound core comprises slot part and tooth portion; It is characterized in that the tooth portion on the said wound core is for being obliquely installed, the slot part on the said wound core is the flume structure with the corresponding tilting of said tooth portion.Tooth portion is set to the tilting structure, can reduce location torque greatly, makes rotor more level and smooth when rotating, and vibration can not occur now, and then effectively reduce vibrating noise.
The oblique distance of said tooth portion and said slot part is 1 times～1.2 times of tooth pitch width.Preferred oblique distance equals the tooth pitch width.So that further make rotor rotation level and smooth, strengthen magnetic field, the work of magneto is more stable, and efficient is higher.
The width of rebate of said slot part is smaller or equal to 1/2 of the tooth pitch of said tooth portion.Increase the quantity of slot part and tooth portion, help improving the operating efficiency of magneto.
The tooth portion of said wound core is provided with the heat radiation through hole, said heat radiation through hole and extraneous UNICOM.So that supply fluid to flow through, take away the heat of wound core.
Beneficial effect: owing to adopt technique scheme, the utility model makes rotor rotation more stable through the design of skewed stator slot formula, can also strengthen magnetic field, is easy to heat radiation, improves the operating efficiency of magneto.

Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand with effect and understand, below in conjunction with the further elaboration the utility model of concrete diagram.
With reference to Fig. 2, Fig. 3, skewed stator slot formula magneto comprises motor housing 1; Be provided with stator 2 in the motor housing 1, stator 2 is provided with the wound core 21 that is used to twine magnet exciting coil, and stator is equipped with rotor 3 in 2 chambeies; Be fixed with magnetic links 31 on the rotor 3; Wound core 21 comprises slot part 211 and tooth portion 212, and the tooth portion 212 on the wound core 21 is for being obliquely installed, and the slot part 211 on the wound core 21 is the flume structure with tooth portion 212 corresponding tiltings.
With reference to Fig. 1, the wound core 21 of the stator of existing magneto, its slot part 211 all laterally arranges with tooth portion 212 vertically; Slot part 211 is the straight trough structure, has no angle, when the magnetic pole of magneto runs to next tooth; Produce very big stiction square and shake, make magneto be difficult for starting and running, jitter phenomenon causes the operating noise of magneto to increase; Mechanical structure is fragile, and job insecurity etc. are confirmed.And with respect to the utility model, structure as shown in Figure 3, magnetic pole slowly changes in running, even constant basically, and can not produce sudden change as shown in Figure 1, greatly reduces the moment of resistance when starting, and shakes lessly, operates steadily, and efficient is higher.
With reference to Fig. 3, the oblique distance t1 of tooth portion 212 and slot part 211 is 0.6 times～1.1 times of tooth pitch t2 width.Preferred oblique distance t1 equals tooth pitch t2 width.So that further make rotor rotation level and smooth, strengthen magnetic field, the work of magneto is more stable, and efficient is higher.The width of rebate of slot part 211 is smaller or equal to 1/2 of the tooth pitch of tooth portion 212.Increase the quantity of slot part 211 and tooth portion 212, help improving the operating efficiency of magneto.
Be provided with heat radiation through hole 22 in the wound core 21, heat radiation through hole 22 and extraneous UNICOM.So that supply fluid to flow through, take away the heat of wound core 21.The fluid of flowing through in the heat radiation through hole 22 can be a gas, also can be liquid.Can be furnished with fin outside the motor housing 1, so that further realize thermolysis.Outside motor housing 1, fan blade can be set, fan blade is installed in the rotating shaft of rotor 3.Heat radiation through hole 22 can pass through some heat radiation conduits and extraneous UNICOM, and the opening of heat radiation conduit is positioned at fan blade one side.When rotor 3 rotates, drive the rotation of fan blade, fan blade is impelled air flow, and then makes the air heat radiation through hole 22 in the wound core 21 of flowing through, and then takes away heat, reaches to guarantee that magnetic links 31 is in the purpose of the low state of temperature.
More than show and described basic principle of the utility model and the advantage of principal character and the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection range to be defined by appending claims and equivalent thereof.
