Ferromagnetic Windings in Electric Motors: Can They Operate?

[ja3863]

Can the wire windings in an electric motor be ferromagnetic and still operate? Why?

 

[Bob S]

The motor could still operate with (formvar-enamel coated) ferromagnetic wires, but it would be a poor choice in part because it is very resistive relative to the same size copper wire. Eddy currents in the wire are lower than in copper, due to the higher resistance. The magnetic properties of a ferromagnetic wire might alter the magnetic design of the motor poles or armature, and degrade the motor performance.

Yes, the wire windings in an electric motor can be ferromagnetic and still operate. In fact, ferromagnetic materials are commonly used in electric motors because of their ability to efficiently conduct and amplify magnetic fields.

Ferromagnetic materials, such as iron, nickel, and cobalt, have a high magnetic permeability, meaning they can easily be magnetized and retain their magnetism. This makes them ideal for use in electric motor windings, which require a strong and stable magnetic field to function properly.

Additionally, the ferromagnetic windings in electric motors are typically insulated to prevent short circuits and overheating. This insulation does not affect the magnetic properties of the material, allowing it to still function effectively.

In conclusion, the use of ferromagnetic windings in electric motors is a common and efficient choice due to their strong magnetic properties and ability to operate effectively within the motor.
