Electric motor theory
An electric motor is an electrical machine that converts electrical energy into mechanical energy. Most electric motors operate through the interaction between the motor's magnetic field and electric current in a wire winding to generate force in the form of torque applied on the motor's shaft. An electric … See more Early motors Before modern electromagnetic motors, experimental motors that worked by electrostatic force were investigated. The first electric motors were simple electrostatic devices described … See more Electric motors operate on one of three physical principles: magnetism, electrostatics and piezoelectricity. In magnetic motors, magnetic fields are formed in both the … See more AC induction and synchronous motors are optimized for operation on single-phase or polyphase sinusoidal or quasi-sinusoidal waveform power … See more The two mechanical parts of an electric motor are the rotor, which moves, and the stator, which does not.
