Order No. WC 96 Customer's No. Sequence Starter motor K We have now preliminarily tested this motor on the bench and measured the resistances of the windings etc. With the teazer winding included it was found that the pinion and armature would slide out to its final position with a current of 13.0 amperes. The total movement we found to be .750" and the main switch contacts just made contact when the armature moved .55" from the off position. With a motor current of 15 amperes the motor would turn slowly as well as being held out, the volts across Signed could This Sheet must be filed on completion of the work. | ||
