... equal). The downside is that you will drain the battery faster. For example, if you were drawing 10A from a 10Ah battery you would drain the battery in about an hour, whereas if you were drawing 20A you would drain the battery in about half an hour. If you increase to a higher amperage draw controll ...

Stepper motor



A stepper motor or step motor or stepping motor is a brushless DC electric motor that divides a full rotation into a number of equal steps. The motor's position can then be commanded to move and hold at one of these steps without any feedback sensor (an open-loop controller), as long as the motor is carefully sized to the application in respect to torque and speed.Switched reluctance motors are very large stepping motors with a reduced pole count, and generally are closed-loop commutated.
