The shaft of a stepper motor is directly connected to a lead screw that drives a worktable in an x-y positioning system. The motor has a step angle = 5(. The pitch of the lead screw is 6 mm, which means that the worktable moves in the direction of the lead screw axis by a distance of 6 mm for each complete revolution of the screw. It is desired to move the worktable a distance of 300 mm at a top speed of 40 mm/sec. Determine
(a) The number of pulses and
(b) The pulse frequency required to achieve this movement.
