Question

The following information is given in connection with an alternator: slots =144; poles =8; rpm =900; turns per coil =6;ϕ−1.8.×10⁴ ; coil span - slots 1 to 16 ; winding = whole-coiled three-phase; winding connections = star. Calculate:

the voltage per phase

Answer 1

To calculate the voltage per phase in an alternator, we use the formula: Voltage per phase = (2 x pi x rpm x ϕ x turns per coil) / (60 x poles). Using the given values, we substitute them into the formula and find that the voltage per phase is 413,056 V.

Step-by-step explanation:

To calculate the voltage per phase in an alternator, we can use the formula: Voltage per phase = (2 x pi x rpm x ϕ x turns per coil) / (60 x poles).

Using the values provided: slots = 144, poles = 8, rpm = 900, turns per coil = 6, ϕ = 1.8 x 10⁴, we can substitute these values into the formula to calculate the voltage per phase.

Voltage per phase = (2 x 3.1416 x 900 x 1.8 x 10⁴ x 6) / (60 x 8) = 413,056 V.
