Stepper motor

Computer animation of a streamlined stepper electric motor (unipolar).
Framework 1: The leading electromagnet (1) is switched on, bring in the closest teeth of the gear-shaped iron rotor. With the teeth straightened to electromagnet 1, they will be somewhat countered from ideal electromagnet (2 ).
Structure 2: The leading electromagnet (1) is turned off, and the right electromagnet (2) is stimulated, pulling the teeth right into placement with it. This causes a turning of 3.6 ° in this example.
Frame 3: The bottom electromagnet (3) is stimulated; another 3.6 ° rotation happens.
Frame 4: The left electromagnet (4) is stimulated, revolving once more by 3.6 °. When the top electromagnet (1) is once again made it possible for, the blades will have turned by one tooth setting; given that there are 25 teeth, it will certainly take 100 actions to make a complete turning in this example.
A stepper motor or action electric motor or stepping electric motor is a brushless DC electric motor that splits a complete turning right into a variety of equal actions. https://en.wikipedia.org/wiki/Ball_screw can after that be commanded to relocate and hold at one of these steps with no placement sensor for comments (an open-loop controller), as long as the motor is very carefully sized to the application in regard to torque and also rate.

Magnet are huge tipping electric motors with a reduced pole count, as well as normally are closed-loop commutated.
