Computer animation of a streamlined stepper motor (unipolar).
Structure 1: The leading electromagnet (1) is turned on, bring in the nearest teeth of the gear-shaped iron rotor. With the teeth lined up to electromagnet 1, they will be slightly countered from best electromagnet (2).
Frame 2: The top electromagnet (1) is shut off, and also the ideal electromagnet (2) is stimulated, pulling the teeth right into alignment with it. This causes a rotation of 3.6 ° in this example.
Frame 3: The bottom electromagnet (3) is energized; an additional 3.6 ° rotation occurs.
Mount 4: The left electromagnet (4) is energized, turning again by 3.6 °. When the leading electromagnet (1) is once again enabled, the rotor will certainly have turned by one tooth placement; because there are 25 teeth, it will certainly take 100 steps to make a complete rotation in this example.
A stepper motor or action electric motor or stepping electric motor is a brushless DC electric motor that divides a complete turning right into a number of equal actions. The motor’s setting can after that be regulated to move and also hold at one of these steps without any kind of position sensor for feedback (an open-loop controller), as long as the motor is carefully sized to the application in respect to torque and rate.
Changed reluctance motors are huge tipping electric motors with a lowered pole matter, as well as typically are closed-loop commutated.
