This motor was removed from chassis 9-EX to have the armature changed for the one from motor A2 with the 20° spiral, the resistance of the armature being altered from .0119 ohms to .0086 ohms at 45°C. No electrical bench tests were made subsequent to this change. Tests made on this motor previous to the change on 7 & 8.7.26 will be found in this file. dated 7 to 9.7.26 but do not include a brake test. EFC. | ||
