Do Electric Cars Have Engines? How Their Motors & Drivetrain WorkThe rotor is the rotating element of an electric motor that has magnets ... to modulate DC current (brushless DC motors) and ones that use AC current (permanent-magnet synchronous motors).
Before the digital age, when transistors were expensive, unreliable, and/or nonexistent, engineers had to use other tricks to do things that we take for granted nowadays. Motor positioning, for ...
