Labview Lecture november 24

 So These pictures might not particularly be from the same lecture or from the 24 at all but that's not the point because the first picture has a stepper motor and that's what this entry is all about anyway. It is what allows for two devices to be run at the same time, at opposite times, or not at all as it opens/closes circuits based on programming, the bottom picture looks more like a relay but whatever.

A stepper motor is an electric motor that rotates in discrete step increments. The movement of each step is precise and repeatable; therefore the motor's position can be controlled precisely without any feedback mechanism, as long as the motor is carefully sized to the application.

There are two common winding arrangements for the electromagnetic coils: bipolar and unipolar. The described stepping sequence utilizes the bipolar winding. Each phase consists of a single winding. By reversing the current in the windings, electromagnetic polarity is reversed. A unipolar stepper motor has one winding with center tap per phase. Each section of windings is switched on for each direction of magnetic field.
