| -2- Contd. It will be seen that for each given ampere value it is expedient to think of Four E.M.F's Four fluxes per pole and Four torques. designated :- E ee es er ØE Øe Øs Ør TE Te Ts Tr{Capt. F. W. Turner - Finance} those underlined being the quantities to which reference has already been made. Of the four columns the first and last correspond respectively to input and output brake test conditions, and the second and third respectively to conditions (2) and (3) as above defined. Of the quantities already considered there are two E.M.F's, e.g. E, ee: two fluxes per pole, e.g. Øe Øs; and two torques e.g. Ts and Tr.{Capt. F. W. Turner - Finance} There is a relation between ee and Øe expressed generally by the equation e = a Ø where a is a fixed quantity, containing the speed, and there is a relation between Ts and Øs expressed generally by the equation T = b Ø where b is a fixed quantity, containing the current. | ||
