The generated voltage will change by a factor of 8. 16. A 6 pole machine is rotating at a speed of 1200rpm. This speed in mechanical rad/sec and electrical radians per second is respectively
A. 40π, 40π/3
B. 120π, 40π
C. 20π, 60π
D. 40π, 120π
Answer:A
The generated voltage will change by a factor of 8. 16. A 6 pole machine is rotating at a speed of 1200rpm. This speed in mechanical rad/sec and electrical radians per second is respectively
A. 40π, 40π/3 B. 120π, 40π C. 20π, 60π D. 40π, 120π
Explanation: N = 1200rpm,P = 6 and f = PN/120 = 60 cycles per sec.
