How to determine whether the motor has a copper core or an aluminum core?

Nowadays, many motors are aluminum core wire instead of copper core wire, so how to distinguish whether the motor is copper core or aluminum core? Today to briefly analyze for you

1. price, in the same product, the price of the motor or transformer with aluminum core will be lower than the copper core.

2. volume, the volume of the aluminum core motor or transformer is significantly higher than the same type of motor or transformer, because the use of aluminum core, must increase the cross-sectional area of the wire.

3. weight, the same motor power, because the density of aluminum is lower than copper, aluminum core is lighter than copper core.

4. Temperature rise, at the same motor power, the heat temperature of aluminum is slightly higher than that of copper. The longer the time the more obvious, therefore, copper performs better than aluminum in the load.

5. nameplate, the regular motor manufacturer will state on the motor: "This motor uses aluminum wire winding, in line with the national lso900 standard", and other similar content.

The above is Vshida for you to distinguish between the motor is a copper core or aluminum core of the five methods, I hope it will help you, for more information, please feel free to consult us.
