ue occurs at E in Figs. 432, 433, the flux densityfalling off uniformly on either side and reaching zero at the points C and G.If we assume for the moment that the maximum flux density is unity andthat the motor is bipolar, so that each pole subtends an angle tt, we see that 2the flux density at… … Fig. 433 negative, the resultant flux being equal to the shaded area, on the assump-tion that the motor has an axial length of i cm. Calling this flux O we have *=(-¥)-(i-)=i(-v:). dx The number of turns in series in this stator coil of width dx will be — .T,. TT The linkages will therefore be O dx…
