Is there a single-word adjective for "having exceptionally strong moral principles"? Duston Maynes is an Automotive Repair Specialist at RepairSmith. The oscillator will operate in two modes: the first is a constant frequency and a variable duty cycle, and the second is a variable frequency. Stepper motors with six wires are unipolar and have one winding per phase (like the bipolar steppers) but with a center tap. Thisnway you can measure BEMF, number of steps per revolution, maybe even torque constant- if you use some load on the phases. The multimeter will beep. Duston holds an Associates degree in Automotive/Diesel Technology from The Universal Technical Institute of Arizona and is a Certified Diagnostic Technician and Automobile Mechanics Technician through BMW STEP. In that case, it is possible your stepper rotator needs replacing because this indicates too much resistance against the electrical current flow in the motor compartment of steps per second (SPM). I wanted to achieve a clear simple representation and differences between the individual modes. Power supplu has outputs V+ and ground. Values greater than this indicate a potential problem and values significantly greater than this indicate the winding has failed opened.
