Figure 1: Windings of a three-phase brushless DC motor are driven in a set sequence

­The first idea that electricity could be used to produce rotary motion originates in the 1740s in experiments by a Scottish Benedictine monk, Andrew Gordon. It took nearly another century before a practical battery-operated version appeared in 1834 and then, through the work of Tesla and others, the ground wa
