Which type of machines have a large number of poles per phase?

(a) high voltage machines and machines with high value of flux per pole

(b) high voltage machines and machines with small value of flux per pole

(c) small voltage machines and machines with high value of flux per pole

(d) small voltage machines and machines with low value of flux per pole

I got this question by my college director while I was bunking the class.

My question is taken from Armature Design topic in portion Design of Synchronous Machines of Design of Electrical Machines

Correct choice is (b) high voltage machines and machines with small value of flux per pole

Easiest explanation: The high voltage machines have a large number of poles per phase. The small value of flux per pole per phase also results in large number of poles per phase.
