In a rotating electrical machine with 2 poles on the stator and 4 pole

1.	In a rotating electrical machine with 2 poles on the stator and 4 poles on the rotor, spaced equally, the net electromagnetic torque developed is ____________(a) maximum(b) zero or no torque is developed(c) minimum(d) none of the mentionedI had been asked this question in homework.My doubt is from Torque Production and Dynamic Equations topic in section Basic Concepts in Rotating Machines of Electrical Machines
Answer» The correct choice is (b) ZERO or no torque is developed Easiest EXPLANATION: In a MACHINE with 2 stator poles and 4 rotor poles spaced equally, the force of ATTRACTION will be cancelled due to the force of repulsion, and hence the net electromagnetic torque will be zero.
