l      The electrical machinery for not brushes the structure, the load characteristics is outstanding, the low-speed performance is good, the start torque is big, the starting current small, meets the electric car frequent starting need, saves the electrical energy.

l      The electrical machinery the electrical machinery highly effifective moves in the entire speed range, compared to has brushes the direct current machine, the exchange frequency conversion electrical machinery (only in fixed spot appendix efficiency high) compares has the archery target enhancement.

l      Does not produce the spark. Does not need to replace brushes, the structure compact, overload capacity, the service life is long.

l      The electrical machinery uses the jack-in rare earth magnet steel, has specially suitably jolts, starts repeatedly, high speed, resists with every effort the starting greatly, is reversing the movement need.

l      The electrical machinery rotor has the strong magnetic field, when glide and stopping generates electricity the effect to be good, does not need to absorb the battery capacity excitation (to have brushes direct current machine or alternating current machine needs), the energy back coupling effect is good, the electric brake effect is good.

l      The electrical machinery uses the forced-air cooling or the water cooling, the temperature is low, the electrical machinery uses the import oiliness high speed bearing, exempts the maintenance, the reliability is high, the electrical machinery life is long.

l      The electrical machinery has the horizontal type, the hanging, may bring raised along to stop the mouth end cover, may use the double axle elongation, the spline axle elongation, may act according to the entire vehicle request and the rear axle of car parameter request quantity body makes to order each kind of voltage, each kind of rotational speed each kind of power request electrical machinery, may make the electrically operated electricity generation dual purpose electrical machinery.
