BASIC Stamp I Application Notes
For each pulse or step input, the stepper motor rotates a fixed angular increment; typically 1.8 or 7.5 degrees. output bits are too precious to waste as simple inverters, so we give that job to two sections of the ULN2003 inverter/driver. The second difference between this and other stepper … View This Document
Motor Controller – Wikipedia, The Free Encyclopedia
Smaller sizes of direct on-line starters are manually operated; larger sizes use an electromechanical contactor to switch the motor circuit. These are therefore often called "sensorless" control methods. Stepper motor controllers … Read Article
