Question

An armature of a three-phase alternator has 180 slots. The alternators have 6 poles. Calculate

a) β angle in radians
b) Distribution factor

Answer 1

The β angle in radians is 0.1745 and the distribution factor is 0.964.

Step-by-step explanation:

To calculate the β angle in radians, we can use the formula: β = π / (2 * number of poles / number of slots). In this case, the number of poles is 6 and the number of slots is 180. Plugging in these values, we get: β = π / (2 * 6 / 180) = 0.1745 radians.

To calculate the distribution factor, we can use the formula: Distribution factor = sin(β / 2) / (β / 2). Plugging in the value of β from the previous calculation, we get: Distribution factor = sin (0.1745 / 2) / (0.1745 / 2) = 0.964.
