Stepper Motors

precision that moves. 

Stepper motors are synchronic motors.  The rotor follows an electrically charged magnetic field. The stepper motor uses a closed loop control system as opposed to the servomotor. This means that position and the number of revolutions are known even without sensor technology by principle. In addition, stepper motors are highly reliable and long-lasting due to their precision and economical construction, even in exteme environments.
