It is extremely important to emphasize that the concept of force is relatively based on the Lorentz force law, considering that it is perpendicular to the wire and to the magnetic field. In the case of a rotary motor, a rotating member, called a rotor, can be imparted. The rotor performs the rotation by the wires and the magnetic field are arranged so that a torque can be developed on the rotor center line. Most magnetic motors are rotating, but there are also linear types. In one of a rotating motor, the rotating part is the rotor, and the stationary part, is the stator. The motor consists of electromagnets inserted into grooves of the ferromagnetic component, which together make up the rotor body.
Most electric motors perform their due tasks through the interaction between the electromagnetic fields ac motors, however, can be found other different types of engines based on different electromechanical phenomena, such as electrostatic forces, for example. The fundamental concept in which all electromagnetic motors are based is that there is a mechanical force at all when the electric current is being driven if it is immersed in a magnetic field.
