Explanation: We know θelec = P/2θmech ⇒ d/dt(θelec) = P/2d/dt(θmech) ⇒ ω = P/2ωm 3. A pole pitch in electrical machine _____________
A. = 180° electrical
B. = 180° mechanical
C. > 180° electrical
D. < 180° electrical
Answer:A
Explanation: We know θelec = P/2θmech ⇒ d/dt(θelec) = P/2d/dt(θmech) ⇒ ω = P/2ωm 3. A pole pitch in electrical machine _____________
A. = 180° electrical B. = 180° mechanical C. > 180° electrical D. < 180° electrical
Explanation: Pole pitch is always expressed in electrical degrees, rather than in mechanical degrees.
