Polyphase motor
WebPolyphase reaction synchronous motors. Abstract: THE reaction synchronous motor in its present form (salient-pole rotor without field coils) is one of the oldest types of electric motors, antedating the induction motor by many years. At first it was used only in connection with instruments, such as the oscillograph etc.; later its simplicity ... Web1888 - April - Galileo Ferraris makes public his AC polyphase motor first conceived in 1885. His motor works without a commutator, this development finally makes the AC motor efficient, and therefore competitive with DC motors. The motor report was first published at the Royal Academy of Sciences in Turin.

WebThis chapter discusses polyphase induction motors. The standard 3-phase powered motor applied to the widest range of drives. Standard 3-phase motors have power ratings from about 60 W upwards. The manufacturers produce motors to suit the load requirements, mains voltages, operating times and starting requirements. WebHigher drive-motor-compressor system efficiency, saving of 1% on energy consumption. For example, it can be evaluated at $2.8M for an 80 MW machine running full-time for 5 years. Better power factor management, lower operating energy costs. Less maintenance & less spare parts because of the simplicity of the induction motor.
WebNikola Tesla conceived the basic principals of the polyphase induction motor in 1883, and had a half horsepower (400 watt) model by 1888. Tesla sold the manufacturing rights to George Westinghouse for $65,000. Most large ( > 1 hp or 1 kW) industrial motors are poly-phase induction motors. By poly-phase, we mean that the stator contains multiple ...
