For a P-pole machine, the relation between electrical and mechanical degrees is given by _____________
A. θelec = 2/P θmech
B. θelec = 4/P θmech
C. θmech = P/2 θelec
D. θelec = P/2 θmech
Answer:A
For a P-pole machine, the relation between electrical and mechanical degrees is given by _____________
A. θelec = 2/P θmech B. θelec = 4/P θmech C. θmech = P/2 θelec D. θelec = P/2 θmech
Explanation: For a P-pole machine, P/2 cycles of EMF will be generated in one revolution, and thus θelec = P/2 θmech. 2. What is the relation between ‘ω’, angular speed in electrical radians per second and ‘ωm‘, angular speed in mechanical radians per second, for a P-pole machine?
