What is the step angle of a permanent-magnet stepper motor having 8 stator poles and 4 rotor poles?
A. 60º
B. 45º
C. 30º
D. 15º
Answer:B
What is the step angle of a permanent-magnet stepper motor having 8 stator poles and 4 rotor poles?
A. 60º B. 45º C. 30º D. 15º
Explanation: Step angle is defined as =(Ns-Nr)/(Ns+Nr)*360 where Ns is the number of stator poles and Nr is the number of rotor poles.
