1.	If a hybrid stepper motor has a rotor pitch of 36º and a step angle of 9º, the number of its phases must be(a) 4(b) 2(c) 3(d) 6The question was posed to me in an interview.My enquiry is from Stepper Motors in section Control System and Components of Control Systems
Answer» The correct answer is (a) 4 For EXPLANATION I WOULD say: Step ANGLE is defined as =(Ns-Nr)/(Ns+Nr)*360.
