WebIn fact, 90% of industrial motors are induction motors. Nikola Tesla conceived the basic principles of the polyphase induction motor in 1883 and had a half horsepower (400 watts) model by 1888. Tesla sold the manufacturing rights to George Westinghouse for $65,000. Most large ( > 1 hp or 1 kW) industrial motors are polyphase induction motors. http://news.benevelli-group.com/index.php/en/97-ipm-vs-spm-electric-motors.html
An induction motor or asynchronous motor is an AC electric motor in which the electric current in the rotor needed to produce torque is obtained by electromagnetic induction from the magnetic field of the stator winding. An induction motor can therefore be made without electrical … See more In 1824, the French physicist François Arago formulated the existence of rotating magnetic fields, termed Arago's rotations. By manually turning switches on and off, Walter Baily demonstrated this in 1879, effectively the first … See more The method of changing the direction of rotation of an induction motor depends on whether it is a three-phase or single-phase machine.
