Description
Technical field
The utility model relates to a kind of hub-type electric rotating machine.
Background technology
At present, motor is the widely used and huge a kind of product that consumes energy of the upper every field of society, and how to improve the efficiency of motor, the energy consumption reducing motor becomes the direction of motor development.It is simple, reliable that magneto has structure; Volume is little, lightweight; Loss is little, efficiency is high, noise is little; The shape and size of motor such as easily can to change at the advantage, thus obtain in every field and use widely.
Along with electric bicycle comes into the market in a large number, someone attempts research and development high-power electric motorcycle, electric automobile with replacing fuel oil car always, does not make good so far, compares with electric motor car and traditional fuel-engined vehicle, be equivalent to replace fuel oil with battery, replace engine with motor.Due to the energy density (energy that Unit Weight stores of battery, W h/kg) well below fuel oil, if use jumbo battery cost too high, being equipped with jumbo lithium battery integral vehicle cost can increase several thousand yuan even several ten thousand yuan, far above the price of fuel motorcycle, fuel-engined vehicle; The performance of traditional structure motor can not be directly applied for electric motor car again, as large in current high-power permanent magnet electric rotating machine no-load current, efficiency is low, moment of torsion is little, temperature rise, poor reliability, cause the power performance of electric motor car and continue ability far below fuel vehicle, therefore, battery and motor are the core of electric motor car, are again the keys of restriction electric motor car development simultaneously.
A kind of hub-type electric rotating machine in electric motor car at present, the rotor comprising stator and rotate relative to stator, described rotor comprises outer wheel hub, permanent magnet, bearing and end cap, described end cap is connected with outer wheel hub, thus form the cavity that can place stator, permanent magnet is provided with inside described outer wheel hub, described end cap is connected with bearing, described stator comprises axle, support, silicon steel sheet, coil and position transducer, described axle matches with bearing, described support is fixedly connected with axle, the cylindrical of described support is provided with silicon steel sheet, the excircle of described silicon steel sheet is provided with line embedding groove, described coil embeds in line embedding groove.Its shortcoming is: the inflection point accurately cannot learning rotor, causes motor rotation efficiency low.
Summary of the invention
The purpose of this utility model is to solve above-mentioned the deficiencies in the prior art, provides a kind of and accurately can know that the inflection point of rotor is to improve the hub-type electric rotating machine of motor rotation efficiency.
To achieve these goals, a kind of hub-type electric rotating machine designed by the utility model, the rotor comprising stator and rotate relative to stator, described rotor comprises outer wheel hub, permanent magnet, bearing and end cap, described end cap is connected with outer wheel hub, thus form the cavity that can place stator, permanent magnet is provided with inside described outer wheel hub, described end cap is connected with bearing, described stator comprises axle, support, silicon steel sheet, coil and position transducer, described axle matches with bearing, described support is fixedly connected with axle, the cylindrical of described support is provided with silicon steel sheet, the excircle of described silicon steel sheet is provided with line embedding groove, described coil embeds in line embedding groove, described position transducer fixes with axle and end cap respectively, and the inner periphery of described rotor is provided with the through hole for embed permanent magnet relative with described line embedding groove spaced apart.Position transducer, by accurately knowing the inflection point of rotor, improves the running efficiency of motor, and due to the through hole for embedding permanent magnet be spaced, reduce the production cost of motor.
Further, described through hole be rectangle arrange and in end points place arc-shaped transition.
Preferably, described stator diameter is respectively 198.5mm-200.4mm.
Preferably, described stator is provided with 36 line embedding grooves.
Preferably, the stacked thickness of described stator and rotor is 15mm-50mm, and described rotor pole logarithm is that 16-23 is to pole.
The hub-type electric rotating machine of the utility model design is identical with the occupation mode of conventional motor, and this is no longer going to repeat them.
A kind of hub-type electric rotating machine that the utility model obtains, its technique effect is: the deviation post accurately being known rotor by position transducer, improves the running efficiency of motor.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of hub-type electric rotating machine of the utility model.
Fig. 2 is the structural representation of through hole in the utility model.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As shown in Figure 1, a kind of hub-type electric rotating machine that the utility model provides, the rotor 2 comprising stator 1 and rotate relative to stator 1, described rotor 2 comprises outer wheel hub, permanent magnet, bearing and end cap, described end cap is connected with outer wheel hub, thus form the cavity that can place stator, permanent magnet is provided with inside described outer wheel hub, described end cap is connected with bearing, described stator 1 comprises axle, support, silicon steel sheet, coil and position transducer, described axle matches with bearing, described support is fixedly connected with axle, the cylindrical of described support is provided with silicon steel sheet, the excircle of described silicon steel sheet is provided with line embedding groove 3, described coil embeds in line embedding groove 3, described position transducer fixes with axle and end cap respectively, and the inner periphery of described rotor 2 is provided with the through hole 4 for embed permanent magnet relative with described line embedding groove spaced apart.Position transducer, by accurately knowing the inflection point of rotor 2, improves the running efficiency of motor, and due to the through hole 4 for embedding permanent magnet be spaced, reduce the production cost of motor.
