According to estimates, fractional electric motors contain approximately 9%-10% copper by weight, on an average. Remember that the copper wire inside is No. 2 copper wire, which will not fetch you high price.
What grade of copper is in electric motors?
The copper content varies among different types of motors, while small motors have a higher percentage of copper per weight than heavy motors. On average, fractional electric motors are 9-10 percent copper by weight. AC motors average 7-9 percent copper; DC motors have 15-18 percent copper content.
