Can the copper wire in the motor be replaced by aluminum wire? What's the difference if it can be compared with copper wire?
The resistivity of aluminum wire is higher than that of copper wire, and the calorific value is relatively higher under the same working current. If the calorific value is reduced, it is best to use materials with low resistivity, such as copper and silver. Of course, the best cost performance is copper, which has better ductility, less oxidation and better durability than aluminum.
