dc stands for Direct Current. this is a term used mostly for batteries and other acid-related voltage sources. A DC machine, simply put, is a machin which runs of off dc current. pleace note that just because something takes batteries, does not make it a dc machine. it has to run directly from the batteries without a special component which can turn dc energy to ac energy.

electrical machines generally fall into 2 groups:ac and dc.dc stands for direct current and ac stands for alternative current.when a machine uses dc current to work or it produces dc current we call it a dc machine.
