The electromechanical-energy-conversion process takes place through the medium of the electric or magnetic field of the conversion device of which the structures depend on their respective functions.
The Lorentz Force Law gives the force F on a particle of charge q in the presence of electric and magnetic fields.
– Electromechanical energy conversion theory is the cornerstone for the analysis of electromechanical motion devices. – The theory allows us to express the electromagnetic force or torque in terms of the device variables such as the currents and the displacement of the mechanical system.
In DC motor's d.c current is being used to rotate the shaft to get the mechanical out put motor rotate with magnetic action and do work which rotate the shaft electrical energy converts into mechanical energy.
