Homework is worth 100 points. Each question is worth 10 points.
A. A spool cutting machine with spool diameter of 0.25 meters cuts a piece
of fabric 7 meters long. How many revolutions would the absolute
encoder measure?
Answer: 8.91
B. An absolute encoder is mounted to the motor driving the X-axis lead
screw of a CNC milling machine. If the encoder has a spec of 1500
PPR, a lead of 1 mm, and the lead screw moves a distance of 200
mm, how many revolutions of the lead screw will the encoder count
and what is the resolution of the X-axis?
Answer: 200 revolutions of the lead screw and resolution is .0007 mm
C. A resolver has an input voltage of 24 volts and a transformation ratio of
0.475. What is the output voltage in volts?
Answer: 11.4
