'''Drives''' or [[Engines]] or motors are machines designed to convert energy into useful mechanical motion.Heat engines, including internal combustion engines and external combustion engines burn a fuel to create heat, which then creates motion. Electric drives convert electrical energy into mechanical motion, pneumatic drives use compressed air and others—such as clock work motors in wind-up toys—use elastic energy. In biological systems, molecular motors, like myosins in muscles, use chemical energy to create motion. | |||
