Description

Copper rotor threephase asynchronous based on dual-trench type
Technical field
The utility model is related to motors, more particularly, to a kind of copper rotor that can be improved electric efficiency and reduce motor temperature rise Threephase asynchronous.
Background technology
Motor is the essential power-equipment of electric vehicle.In the prior art, motor includes shell, rotor, determines Son and motor shaft.Motor in the process of running, due to the friction between electromagnetic load and each component, will produce big calorimetric Amount, makes electric motor overheating, motor efficiency is caused to reduce.Existing automobile-used threephase asynchronous generally uses single groove profile cast copper Rotor, in view of motor strength problem, rotor core slot utilizes limited area, and rotor resistance value is larger, and rotor loss is big, and the motor feels hot Greatly, electric efficiency is low.
Utility model content
To solve the above problems, the utility model aim is to provide and a kind of can improve electric efficiency and reduce motor temperature rise The copper rotor threephase asynchronous based on dual-trench type.
The utility model realized by following technical measures, a kind of copper rotor three-phase asynchronous electric based on dual-trench type Machine, including motor stator and the rotor in motor stator, the rotor center are fixed with rotor drive shaft, The rotor includes the end ring being arranged at two ends, and two circles that surrounding rotor drive shaft is axially connected between the end ring turn Sub- item.
The end ring is copper end ring as a preferred method,.
The rotor bar is copper conducting bar as a preferred method,.
The rotor bar is the small rice shape in the big inner end in outer end as a preferred method,.
The end ring and two circle rotor bars are cast into the double-deck mouse cage shape of an entirety as a preferred method,.
The utility model by rotor structure on be provided with surrounding rotor drive shaft two circle rotor bars, so as to abundant Using space, the current density of rotor is reduced, reduces the thermic load of motor stator, improving electric efficiency reduces motor temperature It rises.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model embodiment.
Specific implementation mode
With reference to embodiment and compares attached drawing the utility model is described in further detail.
A kind of copper rotor threephase asynchronous based on dual-trench type of the present embodiment please refers to attached drawing 1, including motor is determined Son and the rotor 5 in motor stator, 5 center of the rotor are fixed with rotor drive shaft 4, and the motor turns Son 5 includes that end ring 3 at two ends is arranged, be axially connected between the end ring 3 surrounding rotor drive shaft 4 two circle rotor bars 2, 1。
Two circle rotor bars of surrounding rotor drive shaft are provided on the rotor structure of this motor, so as to make full use of sky Between, the current density of rotor is reduced, the thermic load of motor stator is reduced, improving electric efficiency reduces motor temperature rise.With For s36r42 threephase asynchronous machines (7.5KW), simulation analysis comparison, 7.5KW dual-trench type copper rotor threephase asynchronous machines are carried out Compared with the mono- groove profile copper rotor threephase asynchronous machines of 7.5KW, using the 7.5KW dual-trench type copper rotor threephase asynchronous machines of this technology 1 percentage point of electric efficiency raising, rotor current density can be made to reduce by 12%, motor stator thermic load reduction by 1%, from And reduce the Wen Sheng of motor.
In the embodiment of a copper rotor threephase asynchronous based on dual-trench type, with reference to figure 1, technical solution in front On the basis of specifically it is also possible that end ring 3 be copper end ring.
In the embodiment of a copper rotor threephase asynchronous based on dual-trench type, with reference to figure 1, technical solution in front On the basis of specifically it is also possible that rotor bar 1,2 be copper conducting bar.
In the embodiment of a copper rotor threephase asynchronous based on dual-trench type, with reference to figure 1, technical solution in front On the basis of specifically it is also possible that end ring 3 and two, which encloses rotor bar 2,1, is cast into the double-deck mouse cage shape of an entirety.
In the embodiment of a copper rotor threephase asynchronous based on dual-trench type, with reference to figure 1, technical solution in front On the basis of specifically it is also possible that rotor bar 1,2 is the small rice shape in the big inner end in outer end.
It is that copper rotor threephase asynchronous and detection method to the utility model based on dual-trench type is explained above It states, is used to help to understand the utility model, but the embodiment of the utility model and be not restricted to the described embodiments, Ren Hewei Changes, modifications, substitutions, combinations, simplifications made by under the utility model principle should be equivalent substitute mode, all wrap Containing being within the protection scope of the utility model.
