Abstract
The utility model provides a high efficiency and low voltage asynchronous motor rotor structure applied to a low speed electric vehicle. The structure comprises a rotor and a number of rotor slots which are arranged on the rotor. A number of rotor slots are a number of closed slots. The cross sections of a number of closed slots are inverted trapezoidal. Each lower bottom side near the center of the rotor is short, and each upper bottom side away from the center of the rotor is long. According to the utility model, the rotor slots are the closed slots, thus the dynamic performance of a motor is improved; with a certain motor peak torque requirement, the volume and the weight of the motor are obviously reduced; the cost of the motor is reduced; motor and system installation are convenient; when the motor has same volume and weight, the dynamic performance and the comprehensive performance of the motor are improved; and the motor has advantages of high efficiency, large power density, low energy consumption and the like.
Description
Technical field
the utility model relates to motor technology field, relates in particular to efficient low-pressure asynchronous machine rotor structure for a kind of low-speed electronic automobile.
Background technology
For energy savings and environmental protection, the application of high efficiency motor is inexorable trend.At present, known high efficiency motor is high-efficiency asynchronous electric motor, high-efficient asynchronous motor possess skills maturation, reliable in structure, steady performance, and its Electromagnetic Design, structural design have special requirement and feature.But motor (particularly low voltage motor) efficiency, power density, peak torque are generally not high.For meeting motor torque demand, substantially take expanded motor volume, weight to improve motor torque.There is in this case the problems such as electric efficiency is not high, power density is little, energy consumption is large, motor cost is high.In the occasion that has strict bulk installation requirement, motor is installed difficulty.Because motor volume is large, weight is large, to the part being connected with motor, require also high again.Cause motor coupling part cost also high or useful life is not long.
Utility model content
In order to overcome the problems referred to above, the utility model provides to society the efficient low-pressure asynchronous machine rotor structure for low-speed electronic automobile that a kind of electric efficiency is high, power density is large, peak torque is large, energy consumption is little and motor cost is low.
The technical solution of the utility model is: efficient low-pressure asynchronous machine rotor structure for a kind of low-speed electronic automobile is provided, comprise rotor and be somely arranged on described epitrochanterian rotor, some described rotor are some closed slots, the cross section of some described closed slots is inverted trapezoidal, bottom near the center of described rotor is short, away from the upper bottom side length at the center of described rotor.
As to improvement of the present utility model, described upper base is circular arc.
As to improvement of the present utility model, described bottom is circular arc.
As to improvement of the present utility model, on cross section, the ratio of the area that some described rotor are shared and the area of described rotor is that 1:5 is between 2:5.
As to improvement of the present utility model, the quantity of some described rotor at 30 grooves between 50 grooves.
The utility model, because rotor adopts closed slot design, has improved the power performance of motor, at motor peak torque, requires one regularly, and volume and the weight of motor obviously reduce, thereby have reduced motor cost, have facilitated the installation of motor and system.When the same volume and weight of motor, improved power performance and the combination property of motor, have that electric efficiency is high, power density is large and the advantage such as energy consumption is little.
Accompanying drawing explanation
Fig. 1 is perspective view of the present utility model.
Wherein: 1. rotor; 2. rotor.
Embodiment
Refer to Fig. 1, what Fig. 1 disclosed is efficient low-pressure asynchronous machine rotor structure for a kind of low-speed electronic automobile, comprise rotor 1 and be somely arranged on described epitrochanterian rotor 2, described rotor 2 is some closed slots, the cross section of some described closed slots is inverted trapezoidal, bottom near the center of described rotor 1 is short, away from the upper bottom side length at the center of described rotor 1.
In the present embodiment, described upper base and described bottom are all circular arc.On cross section, the ratio of the area that some described rotor 2 are shared and the area of described rotor 1 is that 1:5 is between 2:5.The quantity of some described rotor 2 at 30 grooves between 50 grooves.The cross section of some described closed slots can also rectangular or other regular geometric shapes.
In the present embodiment, by emulation and test, motor peak torque is 200% of conventional motors peak torque, and rate improves 2%, has obviously improved power performance and the efficiency of motor.At motor peak torque, require one regularly, volume and the weight of motor obviously reduce.Thereby reduced motor cost, greatly facilitated the installation of motor and system.When the same volume and weight of motor, greatly improved power performance and the combination property of motor.
