2. DC MOTORS
The DC motor runs on direct current (DC) electricity. DC motors are used to run machinery, instead of a internal combustion engine. DC motors can operate from rechargeable batteries, providing the motive power for the electric vehicles.

3. nowadays DC motors are found in applications as small as toys and disk drives, or in large sizes to operate steel rolling mills and paper machines. Modern DC motors are nearly always operated in conjunction with power electronic devices.

4. Stepper Motors
A stepper motor is a brushless dc motor, that can divide a full rotation in many steps . The position of the motor can be controlled without a feedback mechanism ,

5. Dc/stepper motors
DC brush motors rotate continuously when voltage is applied to their terminals. Stepper motors, on the other hand, effectively have multiple "toothed" electromagnets arranged around a central gear-shaped piece of iron
