here's my knowledge of copper motors. it consists of 2 components, stator and rotor. both parts made of stacks of laminations with slots. the rotor slots are filled with copper rods and the stator slots are wired in a certain way.here's my question, if i want to design a motor having a certain spec for power output, rpm, size, etc... how do i design the slots in the rotor ? i have connections for winding stators, but nobody i knew that can answer me the secrets of rotor design. can somebody give me some clues on rotor design? and how are they manufactured? i heard that people just use hammer to push copper rods in the rotor, is that true?thanks for reading my question!
Actually Ba, aluminum requires a TON of energy to extract. You'll only see aluminum being purified near sources of cheap energy. As for why aluminum being cheaper, it's just more plentiful. It all comes down to scarcity, Plus, there is a lot of demand for copper, which will also drive up the price.
