Simultaneously, the invention is characterized in, is not the copper coil that has adopted prior art, but has adopted the coil of aluminum core line 160b.The internal resistance of aluminium is greater than copper.Therefore, in order to reduce internal resistance, the external diameter of coil that need make aluminum core line 160b is greater than described copper coil.
The ductility of aluminium is lower than copper.Therefore, aluminium is easy to externally rupture under the percussion when twining.In addition, aluminium meet water then a little less than, particularly salt solution makes that aluminium is easy to corrode and rupture when contact with salt solution.
Therefore, in motor of the present invention, preferably aluminum coil has the deposited film of the bilayer that spreads on the aluminum core line outside to strengthen intensity and ductility.In addition, double-deck deposited film has increased the insulation property of coil.
Simultaneously, as previously mentioned, the terminal of coil is positioned at power supply respectively and connects tap terminal 128 and neutral terminal 129.This type of coil terminals needs to apply film and exposes heart yearn to be electrically connected from its removal.
Thus, as previously mentioned, it is weak and be easy to fracture that coil exposes the terminal part of heart yearn thereby intensity and ductility, and when described heart yearn and water, be easy to when particularly contact with salt solution corrode.

Preferably coil 160 is forced to be arranged in and make heart yearn expose in the groove 151 and be electrically connected with MAG-MATE terminal 150.Therefore, MAG-MATE terminal 150 needs to be formed by electric conducting material.Certainly, behind the heart yearn 160b that exposes coil 160, MAG-MATE terminal 150 can be electrically connected with heart yearn 160b.
Under this situation, MAG-MATE terminal 150 can not have groove 151.That is MAG-MATE terminal 150 can have the specific part that will contact with the heart yearn 160b of coil 160, and this specific part can have formation insulation division thereon.
In order to strengthen the intensity of MAG-MATE terminal 150, the front portion 152 of MAG-MATE terminal 150 and rear portion 153 form parallel to each other, and bottom 154 forms and is orthogonal to anterior 152 and rear portion 153.In addition, MAG-MATE terminal 150 can have and is parallel to 154 top 155, bottom and integral type is
