Abstract
The invention discloses a rotor insulation sheet which comprises a body and a plurality of fins arranged at the rear end of the body, wherein the rear end surfaces of the fins are provided with at least one convex column. Through structural optimization, a felt ring between a commutator and the rotor insulation sheet can be omitted, and a heat radiating optimization structure of an air convection space formed by the assembly surfaces of the rotor insulation sheet and a motor rotor is realized, and thus, the heat radiating condition of the inner system of the motor can be improved.
Description
Technical field
The present invention relates to a kind of rotor insulation sheet.
Background technology
Rotor insulation sheet at present commonly used comprises the insulating trip body and is located at some fan sheets on the body rear end.When the rotor insulation sheet cooperates with rotor and commutator at motor internal,, between them, add several felt circles usually, cause the increase of operational inconvenience and cost like this for regulating the fit-up gap between commutator and rotor insulation sheet and the rotor; And rotor itself can produce a large amount of heats in the rotation of machine operation process high speed, and in the case, the rotor insulation sheet is direct affected parts, and continuous high temperature environmental requirement rotor insulation sheet must use exotic material, also causes the increase on the cost.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of novel rotor insulating trip, can help rotor easy to assembly, and heat dissipating state is good can guarantee machine operation the time.
For solving the problems of the technologies described above, the present invention has adopted following technical scheme, and a kind of rotor insulation sheet comprises body and the some fan sheets that are located at the body rear end, it is characterized in that: be provided with a projection on the rear end face of described some fan sheets at least.
As a kind of preferred version, described projection is provided with at least two and highly identical.
As a kind of preferred version, described projection is that the center of circle circumferentially evenly distributes on fan sheet rear end face with the body axle center.Produce dynamically balanced problem when avoiding high speed rotating.
As a kind of preferred version, projection is a cylinder, also can be other structures such as prism or stage body, cone etc., and the contact-making surface of all projections or contact point be at grade when guarantee cooperating.Like this, when rotor insulation sheet and commutator assembling, the use that had both reduced or saved the felt circle can form one circulation of air space again in the middle of rotor insulation sheet and rotor two assembled end, help the heat radiation of motor internal.
The present invention is by the optimization of structure, the use of felt circle can be saved between commutator and the rotor insulation sheet, and the fitting surface of having finished rotor insulation sheet and rotor forms the optimizing thermal solution structure in cross-ventilation space, and the heat dissipating state of whole motor internal system is improved.The present invention is higher because of its operating ambient temperature, preferably adopts stability glass-fiber-reinforced polyamide 6 resin materials preferably.
Description of drawings
Fig. 1 is the structural representation of rotor insulation sheet;
Fig. 2 is the cutaway view of rotor insulation sheet along A-A line among Fig. 1.
Embodiment
As shown in Figure 1 and Figure 2, a kind of rotor insulation sheet, comprise body 1 and the some fan sheets 2 that are located at the body rear end, at least be provided with a projection 4 on the rear end face 3 of fan sheet, in the present embodiment, projection is equipped with one on each fan sheet, can adjust the other end and commutator fit clearance during assembling, to save the usage quantity of felt circle, save cost.Projection is to do circumferentially evenly to distribute on fan sheet rear end face 3 in the center of circle with the body axle center.The rear end face of projection 4 contacts with the rotor mating surface, has so just formed the space of rotor insulation sheet rear end face to the top of projection, and air was mobile when this space will help machine operation, improves the heat dissipating state of motor internal.Simultaneously machine operation the time, fan sheet 2 and projection 4 quicken surrounding air and flow when rotor insulation sheet high speed rotating, play the effect of fan, have further improved the heat dissipating state of motor.
Certainly; the profile of the projection on the described rotor insulation sheet is not limited only to cylinder, prism and stage body; other can be implemented in the body of other structures that uses and strengthen the function of motor radiating effect that saves the felt circle in the assembling, also drop on protection scope of the present invention.
Claims (6)
