thus, the total primary current of the first motor, or supply
current:

/„ = Ii + /oo

= «(/i - if.),

where:

/i = &i +'«

and the primary impressed voltage of the first motor, or supply
voltage:

J71 — IT* i *7 T

Hi o — -v/1 "T~ •*•'Of 0

= «(ffi+M»), (21)

where:

^i == Oi -f- TO/I + ;

#2 = C2 + #0/1 —

and, absolute: ___

__ /~1 2 I "f, 2 ^*?^^

thus:

^' (24)

(22)

Substituting now this value of e in the preceding, gives the
values of the currents and voltages in the different circuits.
34. It thus is, supply current:

power input:

volt-ampere input:

Po = /Eoj Jo/'

.Q =

and herefrom power-factor, etc.
The torque of the second motor is :

The torque of the first motor is:
