AC Motor and improvements
AC motors proved both durable and adaptable. Within the space of two years Tesla had patented over twenty useful modifications of his new motors: to start up under heavy loads, to run at variable speed, or at constant speed, or with polyphase power supply, to mention a few. The great advantage of polyphase motors is, for a given number of poles, a smoother, more intense whirling field; such motors, in myriad forms, launched the electrical age of heavy industry. A somewhat more modest lineage of AC motors has powered most of the familiar appliances of twentieth-century life, from refrigerators to coffee grinders.
Nikola Tesla invented the induction motor with rotating magnetic field that made unit drives for machines feasible and made AC power transmission an economic necessity.
