-2- contd. (3) Static torque test. Obtain the static torque of the motor in normal condition for the various tabulated values of the main current, eliminating torque losses arising from hysteresis, brush, bearing, and reduction gear friction, in the usual manner. Record the results on that portion of Form 3 which concerns this test, and so determine Φs and es. Complete Form 4 and Form 5. Plot the quantities ee es Φe Φs Ts Tr{Capt. F. W. Turner - Finance} on the form provided (ampere base). Note:- E.H.P. = .001340 x Volts x Amperes. B.H.P. = .00001587 x R.P.M. x pound-inches. EFC. | ||
