Stepper motors
Question3 Stepper motor coils typically draw a lot of current, requiring the use of power transistors to"buffer" the control circuitry to the motor. Explain where you would take your first few measurements to isolate the problem, and why you would measure there. file 03905 5 … Doc Retrieval

Stepper Motor Basics
The Rotating Magnetic Field When a phase winding of a stepper motor is energized with current a magnetic flux is developed in the stator. The direction of this flux is determined by the "Right Hand Rule" which states: "If the coil is grasped in the right hand with the fingers pointing in the direction of the … Content Retrieval
