- Aluminum windings DO compare well to copper windings based on resistivity and density considerations.
- See resistivity - [1] - aluminum is under 2x more resistive than copper.
- But aluminum density is 2.7 g/cm3 - whereas copper is 9 g/cm3. Thus, >3x as heavy in its density. This means that the weight of windings will actually be lighter for the same current flowing through the winding. Which means that a motor of the same power is likely to be lighter (though larger in size) - unless the non-winding parts of the motor are all together heavier because of the larger volume of the motor.
- The relevance for the GVCS is eliminating the need for copper if aluminum from clay is acceptable - such that an electrical power economy can likewise be produce without strategic resources such as copper.
- This article verify that aluminum-wound electric motors are feasible - [2]
