# Machine Motors (DD-530)

> Precision electric motors such as servo motors, stepper motors and brushless DC (BLDC) motors use microcontrollers, sensors and feedback loops to control speed, torque and position very accurately, down to fractions of a degree. They are essential in robotics, CNC machining, medical devices and aerospace. The footage, credited to action.box, shows motors moving with precision.
