Question: A stepper motor has a step angle of 2.25 degrees. Calculate the number of steps for the shaft to make 45 revolutions. A DC motor

A stepper motor has a step angle of 2.25 degrees. Calculate the number of steps for the shaft to make 45 revolutions.
A DC motor is connected to a source of 200 V, and its armature resistance is 1 generates 25 V when running at a speed of 500 rpm. Ohm. The armature 2023/05
Calculate:
i) The starting current
ii) The back e.m.f. when the motor runs at 1000 rpm.
iii) The armature current when the motor runs at 1500 rpm. 105/2
c) Can I use pin A0 of Arduino UNO for Motor Speed Control through the command analog Write(A0, speed)?
