With this principle, motors can be developed to maximize magnetic flux by maximizing the amount of coil area that will influence the magnetic field of the rotating machine.Īn electric motor will have at least one stator and one rotor depending on the design and type of motor. The magnitude of magnetic flux that flows through a conductor will determine the amount of force the coil will exert on another magnetic field, and whether it’s an attractive or repulsive force. Magnetic fields can also be created using magnets, which generate a constant magnetic flux.įlux is defined as the “flow of current through a magnetic field” and describes the rate of flow of the property over a unit area. Conversely, when a counterclockwise current is induced in the coil, a north facing pole will be observed pointing away from the screen.īy changing the direction of current in the wire, a north or south facing pole can be induced in the same coil at different moments. When an electromagnetic coil is induced with a current clockwise to the direction of the wound wire, a north facing pole is observed in the plane facing into your screen. Electromagnetic coils, also known as inductors, are created by taking long enamel coated wire and lapping the wire layer by layer in a circular pattern. Lets take a deeper look into how electric motors work!Įlectric motors use magnetic fields to turn electrical energy into mechanical energy. With the understanding that these magnetic fields are supposed to act against each other to generate rotational motion, the package we place the coils and magnets in can be morphed to suit different purposes. How is this possible you may ask? Because a motor is not a complicated mess of wires and electronics, but is simply a device that creates magnetic fields to act on other, fixed, internal magnetic fields.
