how to judge the motor coil is aluminum coil ?-人生就是搏尊龙

on the market at present the price of copper wire is on the high side, many motor manufacturers use aluminum coil instead of copper wire, as a result, the mechanical and electronic products on the market many of them are aluminium wire motor.

aluminum motor resolution, just to see if thicker winding wire of the stator relatively bulky; or measuring line resistance, you can check it out.

if you want to identify what kind of material, and do not remove the check there is a way.we went up from the principle of understanding is easy to identify:

1, the physical properties of the problem is not easy as aluminum sheet circle copper la sila is very thin, it is generally the same power of the motor to the thicker aluminum number.

2, since the resistance value of the same cross-sectional area of aluminum higher than copper, so as to obtain a current, the aluminum is bound to increase the cross-sectional area, i.e. a large diameter.

3, to make the same power of motor, bold line for aluminium circle suppliers diameter, winding increases, the original design of silicon steel sheet slot can't meet the winding embedded.for this, can only expand the trough, and expand the trough the only way, also can be to increase the diameter and thickness of the stator.
