A 3 phase, 6 pole star connected alternator revolves at 1000 rpm. The ...
Pole = 6, conductor/slot = 8, flux = 0.05
Winding factor KW = 0.96, speed = 1000 RPM
Number of conductor z = slot × conductor/slot = 90 × 8 = 720
Eph = 4.44 Kc Kd f N = 4.44 × 0.96 × 0.05 × 50 × 120 = 1278.72 V
Winding factor KW = 0.96, speed = 1000 RPM
Number of conductor z = slot × conductor/slot = 90 × 8 = 720
Eph = 4.44 Kc Kd f N = 4.44 × 0.96 × 0.05 × 50 × 120 = 1278.72 V

A 3 phase, 6 pole star connected alternator revolves at 1000 rpm. The ...
Given data:
- Alternator: 3 phase, 6 pole, star connected
- Speed: 1000 rpm
- Stator slots: 90
- Conductors per slot: 8
- Flux per pole: 0.05 Wb
- Winding factor: 0.96
To calculate: Phase voltage generated by the machine
Formula used:
- EMF generated per phase = (4.44 x f x N x P x Z x Φ x KW)/1000
- Where,
- f = frequency = P x S / 120 (in Hz)
- N = Speed of rotation (in rpm)
- P = Number of poles
- S = Number of stator slots
- Z = Number of conductors per slot
- Φ = Flux per pole (in Wb)
- KW = Winding factor
Calculation:
- Frequency f = P x S / 120 = 6 x 1000 / 120 = 50 Hz
- EMF generated per phase = (4.44 x f x N x P x Z x Φ x KW)/1000
= (4.44 x 50 x 1000 x 6 x 8 x 0.05 x 0.96)/1000
= 1278.72 V
Therefore, the phase voltage generated by the machine is 1278.72 V (option B).
- Alternator: 3 phase, 6 pole, star connected
- Speed: 1000 rpm
- Stator slots: 90
- Conductors per slot: 8
- Flux per pole: 0.05 Wb
- Winding factor: 0.96
To calculate: Phase voltage generated by the machine
Formula used:
- EMF generated per phase = (4.44 x f x N x P x Z x Φ x KW)/1000
- Where,
- f = frequency = P x S / 120 (in Hz)
- N = Speed of rotation (in rpm)
- P = Number of poles
- S = Number of stator slots
- Z = Number of conductors per slot
- Φ = Flux per pole (in Wb)
- KW = Winding factor
Calculation:
- Frequency f = P x S / 120 = 6 x 1000 / 120 = 50 Hz
- EMF generated per phase = (4.44 x f x N x P x Z x Φ x KW)/1000
= (4.44 x 50 x 1000 x 6 x 8 x 0.05 x 0.96)/1000
= 1278.72 V
Therefore, the phase voltage generated by the machine is 1278.72 V (option B).
