AC Motors: Principle of Operation - Johnson Electric
Synchronous Motors. Synchronous ac motors are constant-speed electric motors and they operate in synchronism with line frequency. The speed of a synchronous motor is determined by the number of pairs of poles and is always a ratio of the line frequency.read more
Motors | How to Choose an Electric Motor
Simply put, an electric motor converts electrical energy into mechanical energy. This is achieved by the principle of electromagnetic induction. Electromagnetic induction is the principle that a current carrying conductor, when placed in a magnetic field will have a force exerted on the conductor proportional to the current flowing and the ...read more

linear electric motor - Explain that Stuff
H ave you seen those extraordinary "maglev" (magnetic levitation) trains that float on air instead of rolling on wheels? They're entirely electric but, instead of using ordinary electric motors that spin around, they use a kind of "unwrapped" motor called a linear motor that causes them to move at high speed in a straight line.read more
