Explanation: The other coil-side must be in slot 10=1+coil span=1+9 . 5. The belt factor is defined as the ratio of
A. arithmetic sum of coil EMF to the phasor sum of coil EMFs
B. phasor sum of EMF per coil to the arithmetic sum of EMF per coil
C. phasor sum of coil EMFs to the arithmetic sum of coil EMFs
D. phasor sum of coil EMFs to per phase voltage
Answer:A
Explanation: The other coil-side must be in slot 10=1+coil span=1+9 . 5. The belt factor is defined as the ratio of
A. arithmetic sum of coil EMF to the phasor sum of coil EMFs B. phasor sum of EMF per coil to the arithmetic sum of EMF per coil C. phasor sum of coil EMFs to the arithmetic sum of coil EMFs D. phasor sum of coil EMFs to per phase voltage
Explanation: Belt factor or distribution factor or breadth factor = kd= phasor sum of coil EMFs/arithmetic sum of coil EMFs. 6. The armature winding of a 2-pole, 3-phase alternator for each phase is distributed in a number of slots per phase. The RMS value of the voltage per phase is less than the RMS value of the voltage per coil multiplied by the number of coils in series because the
