Recycling of Electrical Motors

The copper content material differs between completely different engines; small engines have the next share of copper per weight than heavy engines. On common, fractional electrical motors are 9-10 % copper by weight. AC motors common 7-9 % copper; DC motors have 15-18 % copper content material. Sealed items can have lots of copper in them and are sometimes a lot heavier than electrical motors, however the dense liquid inside could make them an actual mess and an environmental hazard to scrub.

Most electrical motors may have about 90% metal weight, so the worth of the metal shall be an enormous consider pricing the product – even when the copper is excessive, the motor could not go up in pricing if the metal is low or flat as a result of it is such a big share of the merchandise’s weight.


Aluminum Or Copper Windings?

One factor we all know can set off a demo employee, electrician, or industrial contractor is to make sure that the transformer, motor, or winding is copper, not aluminum.

We all the time ask for footage to verify an merchandise is engraved so we will fee the merchandise correctly.

This occurs in lots of conditions, from very massive transformers to spare gentle transformers seen inside forged aluminum instances. There are even some sorts that shall be aluminum on one aspect and copper on the opposite.
