As a rule, there’s no perfect material for motor windings: the right choice will depend on the designer’s budget, electrical conductivity, density, and flexibility requirements. Today, there exist so many types of motor winding materials that it can be overwhelming to find the ideal one for a particular application. Motor Winding Materials: A Key to Improving the Performance of Electric Motors These wires provide a path for electric current to flow and create the magnetic field to spin the motor's rotor. Motor windings in electric motors are insulated wires wrapped around a magnetic core (usually laminated soft iron). The stator of an electric motor with copper windings This article presents valuable information about motor windings as well as a few motor winding calculations that designers must know. Wrongly specifying the motor winding wire types, materials, and dimensions are major causes of poor motor performance. One of the critical areas that engineers must consider when designing motors is the winding. These motors generate rotational force due to the interaction between the motor’s magnetic field and electric current in the motor winding.Īs simple as the electric motor’s function might seem, a lot of effort goes into designing and specifying these motors for several applications. Electric motors are essential devices used in a broad range of industries to convert electrical energy into mechanical energy.
