TO CONVERT ELECTRICAL INTO MECHANICAL ENERGY.

Technical

THE FIRST COMMERCIAL INDUCTION MOTOR WAS CONCEIVED BY NICOLA TESLA IN 1888. IT WAS POLYPHASE, BUT THERE WERE NOPOLYPHASE SYSTEMS TO SUPPORT IT. IN 1893 60 CYCLES BECAME THE STANDARD FREQUENCY, WHICH ASSISTED IN POPULARIZING THE INDUCTION MOTOR. AFTER 1900 POLYPHASE INDUCTION MOTORS REPLACED DC MOTORS IN MANY INDUSTRIAL APPLICATIONS. IN 1925 MAJOR IMPROVEMENTS TO THE MOTOR INCLUDED THE SEALED-SLEEVE BEARING, AND DIE-CASTING OF THE ROTOR CAGE (CHEAPER & MECHANICALLY STRONGER). (REF. 2)
