Common Materials Of Motor
Copper
Copper can be drawn into flat shapes to form rectangular winding wires. Rectangular winding wires are integral components in compact and high-performance applications like electric vehicle motors, EV power trains etc.
Steel
Silicon steel offers good shielding properties against electromagnetic interference. Therefore, it is useful in equipment where the radiation needs minimizing, such as medical instrumentation or transport systems like railroads.
Cast Iron
Cast iron is a good choice for an engine block. It is easily sand cast, easy to machine, capable to resist piston wear quite well, and inexpensive as a material.
Silicon steel sheet
The silicon steels are produced in two forms, highly textured grain-oriented alloys and alloys in which the grains are not oriented. Grain orientation is carried out to align the magnetic easy axis.
