Driving motor efficiency

摘要

Since the invention of the battery in 1800 and development of dc motors a few decades later, the simple electric motor has evolved into a sophisticated electrical device with electronic control options. The development of motors first focused on the dc type, as batteries were the primary electrical source at the time. Motor development evolved to the use of induction, synchronous, and other alternating current forms. The use of motors and specification options has developed at an ever-increasing pace, as regulatory requirements and efficiency needs have forced the simple electric motor to use less energy and become smarter. Obviously, ac induction motors have not changed significantly from their origins. However, the way we use and control them has evolved as the designs have become optimized for current uses.
