Please find here notes, videos and quiz for each lecture.
1) You should take a look at the quiz before lecture. You do not need to be able to answer all questions in the quiz before coming to class.
2) You should come to lecture. Likely I will not present the full lecture but we will take a look at the quiz and discuss your questions.
3) If after lecture you can not answer the quiz you should take a look at the slides.
4) If you still have questions after coming to class, asking questions and checking the slides, you should watch the lecture.

Sorry there are some errors in my explanations as I have used the word "current" instead of "torque" and "power" instead of "energy". Energy is needed when you drag an object by force a distance, power is consumed by that force times the speed you drag the object. For a motor the power it produces is proportional to the torque times rpm (seed) and the energy is proportional to the torque times the amount of angular rotation. In a stepper motor, there are not multiple poles but only the stator and rotor teeth align when magnetic fields in the stator teeth align with the field in the rotator teeth.
