A permanent-magnet stepper motor with a 15? step angle is used to directly drive a 0.100 in. lead screw. Determine:
a. The resolution of the stepper motor in steps/revolution,
b. The distance the lead screw travels (in inches) for each 15? step of the stepper motor,
c. The number of full 15? steps required to move the lead screw and the stepper motor shaft through 17.5 revolutions, and
d. The shaft speed (in rev/min) when the stepping frequency is 220 pps.
