What is the working principle of an electric motor ?

Image
Electric motor: A motor is a device which converts electrical energy into mechanical energy. Principle of motor : A motor works on the principle that when a rectangular coil is placed in a magnetic field and current is passed through it. A force acts on the coil which rotates it continuously. An electric motor uses the attraction and repulsion of magnetic fields to produce motion. The simplest is the permanent magnet motor. A simplified version is shown below. Placing a coil of wire inside a permanent magnetic field and fixed so it can freely rotate. Pass a current through the coil of wire and it will rotate to the perpendicular position. Now reverse the current flow and the coil will spin 180 degrees. The brushes and the commutator does the switching directions of the current through the coil at the appropriate moment to keep the coil rotating in one direction. This is the basics of all electric motors. Fleming’s left hand rule above describes the relatio...
