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, Wh/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.
Therefore occurred the hub-type electric rotating machine in electric motor car, comprise the stator with the star-like connection winding of three-phase and the rotor rotated relative to stator, described rotor is made up of outer wheel hub, permeability magnetic material, permanent magnet, bearing, end cap; Described stator is made up of axle, support, silicon steel sheet, winding, position transducer, and form stator core after described silicon steel sheet superposition, the excircle of described stator core is provided with some equally distributed line embedding grooves.Its shortcoming also existed is: the inflection point for rotor detects more difficult, often 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 hub-type electric rotating machine in electric motor car that accurately can record the inflection point of rotor, thus improves motor rotation efficiency.
To achieve these goals, a kind of hub-type electric rotating machine in electric motor car designed by the utility model, comprise the stator with the star-like connection winding of three-phase and the rotor rotated relative to stator, described rotor is made up of outer wheel hub, permeability magnetic material, permanent magnet, bearing, end cap; Described stator is made up of axle, support, silicon steel sheet, winding, position transducer, stator core is formed after described silicon steel sheet superposition, the excircle of described stator core is provided with some equally distributed line embedding grooves, stator tooth is formed between described line embedding groove, described position transducer is positioned on stator tooth, and the excircle top of described stator core is provided with three Hull cells; Described rotor inner periphery is provided with the through hole for placing permanent magnet that is spaced apart and that arrange around stator core.Accurately can be learnt the anglec of rotation of rotor by position transducer, through hole is spaced apart simultaneously, reduces the production cost of motor.
Preferably, between described Hull cell be 10 ° of distributions.
Preferably, described through hole is rectangle setting, and in end points place arc-shaped transition.
Further, described support excircle is provided with some fixed lobes, effectively can reinforce silicon steel sheet.
Preferably, the number of described line embedding groove is 54, and the number of described stator tooth is also 54.
Preferably, the diameter of described stator is 253.5mm-255.4mm.
Preferably, the stacked thickness of described stators and rotators is 15mm-50mm.
