Optimizing High Level Micro Stepping of
... As shown in Figure 4, a DAC is used to give voltage to VREFx with minimum resolution. For example, if a 10-bit DAC is used, and maximum value 1024 stands for 2.5 V, the DAC outputs 2.5 V/1024 = 2.4 mV each step. The regulated current in winding is measured by monitoring the voltage of the sense resi ...

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.
