Air conditioning compressor for vehicles

Abstract

An air conditioning compressor for vehicles, comprising a compressor having a shaft extending from the compressor to the exterior of the compressor and a driving device configured at the exterior of the compressor. The driving device comprises a stator and a rotor. The shaft passes through a shaft hole such that the stator is assembled at the exterior of the compressor. The power transmission lines having different polarities in the stator connect to external power source such that the stator may generate directional (forward or reverse) rotating magnetic torque. The rotor is assembled at the exterior of the stator. A sleeve portion in the rotor connects to the shaft. Thus, a torque is inducted by electromagnetic induction through the stator and then the rotor drives the shaft of the compressor to rotate. Therefore, the air conditioning compressor for vehicles may be driven to operate by way of electrical power.

What is claimed is: 
     
         1 . An air conditioning compressor for vehicles, comprising:
 a compressor having a shaft, the shaft extending from the compressor to the exterior of the compressor; and   a driving device configured at the exterior of the compressor, wherein the driving device comprises:
 a stator having a shaft hole, wherein the shaft passes through the shaft hole such that the stator is assembled at the exterior of the compressor; and 
 a rotor configured at the exterior of the stator, one side of the rotor being recessed to form a receiving slot, the receiving slot being relatively at the exterior of the stator, wherein a sleeve portion is formed in the receiving slot, and connects to the shaft of the compressor. 
   
     
     
         2 . The air conditioning compressor according to  claim 1 , wherein the stator comprises at least one core encircled by a winding, at least two power transmission lines having different polarities extending from the winding, the power transmission lines connecting to an external power source; wherein a plurality of magnetic elements are configured on the internal wall of the receiving slot, the plurality of magnetic elements are spaced at intervals to correspond to the outer surface of the stator.
