AC Motors vs. DC Motors
2 days ago · Brushless DC motors are more efficient than those with brushes, but the efficiency gains are primarily at the lowload or noload areas of the motor performance curve. Other Considerations. For a given amount of mechanical work output, AC motors are usually larger than DC motors, with brushless DC designs being the smallest.
DC Generator
· DC Generator – Construction, Working Appliions. An electrical generator is a machine that converts mechanical energy into electrical energy. It works on the principle of electromagnetic energy conversion. When a mechanical domain is given to the machine it develops a magnetic field that is further converted into electrical energy.
