Abstract
The utility model discloses a double-salient-pole permanent-magnet hub electric motor. The electric motor essentially consists of a stator and a rotor. The stator and the rotor take a double-salient-pole shape. A permanent magnet is arranged on the stator or on the rotor, a concentrated winding is arranged on the stator, and the rotor is integrated with the hub. The stator is fixed on a bracket through the support from a bearing arranged on an axis, and the bracket is fixed with the axis through a screw. The hub electric motor has compact structure, high power density, wide speed-regulating range, reliable and stable operation, easy dismounting and maintenance as well as excellent controllability.
Description
Technical field
The utility model relates to a kind of permanent magnetism wheel hub motor, especially a kind of bisalient-pole permanent-magnet wheel hub motor.
Background technology
The wheel hub motor that is used for electric motor car at present has types such as DC motor, induction motor, brushless, permanently excited direct current motor, switched reluctance motor.DC motor price height, volume and weight is big, and because members such as brush and mechanical commutator are easy to wear, reliability is relatively poor.Induction motor need adopt jumbo variable-frequency variable-voltage device, and speed governing is also relatively poor.The cost of the control system of induction motor is higher than motor itself far away.Brushless, permanently excited direct current motor is subjected to the influence and the restriction of permanent magnetic material technology, and power density is less.The maximum characteristics of switched reluctance machines (SR) are its high reliability, have foolproof electric machine structure and broad speed adjustable range.But from the viewpoint of power conversion, the SR efficiency of motor is not high, and noise and torque pulsation height.
At the deficiency of above-mentioned motor, the utility model was to finish under the subsidy of this project to Guangdong Province's natural science fund to bisalient-pole permanent-magnet wheel hub motor project verification (05006516) in 2005.
The utility model content
The purpose of this utility model is to provide a kind of bisalient-pole permanent-magnet wheel hub motor that is applicable to electric automobile at the deficiency of above-mentioned motor, this motor not only can directly be contained on the wheel shaft, and can mount and dismount easily, have speed adjusting performance simple in structure, that efficient is high and good simultaneously.
Bisalient-pole permanent-magnet wheel hub motor of the present utility model mainly is made of stator and rotor two parts, and stator and rotor are the biconvex electrode structure, and internal stator is extremely gone up the symmetry ground heterogeneous concentrated winding that distributed, stator yoke portion symmetry ground distribution for permanent magnetic iron.
Stator is fixed on the support, and support connects together with axle, and stator, rotor are with spool concentric, and rotor and wheel hub are one, and by bearings, permanent magnet is placed on rotor yoke.
During concrete the application, the axial length of the axial length of this wheel hub motor and the trailing wheel of automobile is complementary; The external rotor of motor and wheel hub are assembled together with friction tight method; Whole motor short-thick type in the form of annular discs.On the salient pole of stator around centralized armature winding, radially relative utmost point winding polyphone is a phase, permanent magnet is inserted in stator yoke portion symmetrically.
Advantage of the present utility model is whole electric machine structure compactness, and motor overall dimension and automobile driving wheel place wheel rim inner chamber coincide, and have effectively utilized the space.Fixed axis carrying working face is stressed rationally.The wheel hub loading regime is similar to orthodox car, and is reliable.Permanent magnet and winding all are positioned on the stator, have guaranteed mechanical strength and the stability of rotor under high-speed cruising.Each parts dismounting of motor is simple, easy to maintenance.
