Abstract
The utility model discloses a commercial electric motor car motor, it includes the rotor, the rotor has the rotor main part, the center of rotor main part is equipped with the shaft hole that an axial runs through, with the circumferencial direction on the outer periphery of rotor main part, a plurality of magnet pieces have set firmly to parallel interval, magnet piece type of being rectangle, the four corners radius is handled. In the assembling process of magnet piece, the difficult magnet piece that takes place bumps the garrulous condition.
Description
Technical field
The utility model relates to a kind of motor structure, particularly relates to a kind of commercial electric vehicle motor.
Background technology
Current electric motor car occupies more and more consequence in daily life, the advantage that commercial electric motor car is steady with outward appearance, loading capacity is large, is more and more subject to business people and welcomes.
Electric vehicle motor primary structure, for arrange stator and rotor in housing, utilizes the electric effect of coil and magnet etc., makes rotor rotary motion constantly.Rotor has rotor subject, with circumferencial direction on the outer circumference surface of rotor subject, is provided with multiple flat thin magnet to parallel interval.Existing flat thin magnet is rectangle, has sharp-pointed corner, when assembling flat thin magnet, corner easily occurring and breaks up, whole flat thin magnet is scrapped.
In addition, in the process that rotor high-speed rotates, rotor subject produces heat, and heat can directly conduction to flat thin magnet, for a long time so, likely cause flat thin magnet temperature rise too high and produce non-reversible high-temperature loss of excitation, and then make motor damage.
Utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of commercial electric vehicle motor, during its assembling, flat thin magnet not easily occurs and breaks up situation.
A kind of commercial electric vehicle motor, it comprises rotor, described rotor has rotor subject, the center of described rotor subject is provided with an axis hole axially run through, with circumferencial direction on the outer circumference surface of described rotor subject, be installed with multiple flat thin magnet to parallel interval, described flat thin magnet is class rectangle, four rounding of angle process.
Preferably, the angle of the rounding of described flat thin magnet is 30-45 °.
Described flat thin magnet adopts adhesive to be pasted on the outer circumference surface of rotor subject.
Described adhesive is insulated heat adhesive, and described adhesive smears formation adhesive layer.
Preferably, the thickness of described adhesive layer is 0.5-1mm.
The beneficial effects of the utility model:
, in the assembling process of flat thin magnet, not easily there is flat thin magnet and break up situation in 1, four rounding of angle process of flat thin magnet of the present utility model.
2, adhesive is insulated heat adhesive, insulation, thermal insulation is good, the heat that can effectively stop rotor to produce when High Rotation Speed is directly passed to flat thin magnet, avoid the rapid temperature rise of flat thin magnet and cause loss of excitation, improve its useful life, when electric motor starting, the current delivery between flat thin magnet and rotor can also be blocked in addition.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Reference numeral illustrates:
Rotor subject 1, axis hole 11, flat thin magnet 2.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, the utility model discloses a kind of commercial electric vehicle motor, it comprises rotor, rotor has rotor subject 1, the center of rotor subject 1 is provided with an axis hole 11 axially run through, and with circumferencial direction on the outer circumference surface of rotor subject 1, is installed with to parallel interval multiple flat thin magnet 2, flat thin magnet 2 is class rectangle, four rounding of angle process.The angle of the rounding of flat thin magnet 2 is preferably 30-45 °.
Flat thin magnet 2 adopts adhesive (not shown) to be pasted on the outer circumference surface of rotor subject 1.Adhesive is insulated heat adhesive, and adhesive smears formation adhesive layer.Preferably, the thickness of adhesive layer is 0.5-1mm.
Above; be only the utility model preferably embodiment; but protection range of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection range of the present utility model.Therefore, protection range of the present utility model should be as the criterion with the protection range of claim.
