What reading level is Design of Polyphase Generators And Motors book?
To quickly assess the difficulty of the text, read a short excerpt:
T, the Polar Pitch (in cm. ).
Stator Slot Pitch, (in mm. ) 12 15. 0 14 16. 4 16 17. 7 18 18. 9 20 20. 0 25 22. 3 30 24. 4 35 26. 0 40 27. 0 From Table 19 we select as appropriate for our motor, a trial slot pitch of about 25 mm. Since T is equal to 325 mm. , we should have: 325 25 = 13 slots per pole.
But the number finally chosen should be a multiple of 3, the number of phases. Consequently let us employ 12 slots per pole, POLYPHASE MOTOR WITH SQUIRREL-CAGE ROTOR 119 (12 \ = ) 4 slots per pole... per phase (pppp). Thus we must o / revise the stator slot pitch to: = 27. 1 mm. \& The Total Number of Stator Slots. Since our machine has 6 poles, we shall have: 12X6 = 72 stator slots.
The appropriate slot layout will be based on 10 conductors per slot and : 4X10 = 40 conductors pppp. And 6X40 10 _, ^ = 120 turns in series per phase. & Let us denote the turns in series per phase by T. Then: ^=120.
THE PRESSURE FORMULA In our discussion of the design of generators of alternating electricity we have become acquainted with the pressure formula : V=KXTX~XM.
