In this case, 8 steps are taken in the forward direction, followed by 2 steps in the reverse direction, repeating this cycle every 1 second.</p> <p>The load angle is seen to increase and decrease as expected, until the 4th step of the second cycle. At that point, the spring's torque exceeds the capability of the stepper motor, causing it to "snap back" suddenly to a negative angle, below the initial starting point! The phase currents of the motor reflect the sequencing of the drive switches in forward and reverse direction.</p> About text formats Tags stepper motor Select a tag from the list or create your own.Drag to re-order taxonomy terms.
