Transformer Enameled Copper Wire Using IEC Standard Class 155/180
Electric motors contain coils to produce the required magnetic
fields. For a given size of motor frame, high conductivity material
reduces the energy loss due to coil resistance. Poorer conductors
generate more waste heat when transferring electrical energy into
kinetic energy.
Because of its high electrical conductivity, copper is commonly
used in coil windings, bearings, collectors, brushes, and
connectors of motors, including the highest quality motors.
Copper's greater conductivity versus other materials enhances the
electrical energy efficiency of motors. For example, to reduce load
losses in continuous-use induction-type motors above 1 horsepower,
manufacturers invariably use copper as the conducting material in
windings. Aluminium is an alternate material in smaller horsepower
motors, especially when motors are not used continuously.
