X.9620 - STARTER MOTOR.

Referring to drawing LeC.1728., we should be glad to know whether the spaces allotted to the main field winding and the teazer winding are in accordance with the requirements indicated by the calculations, for example. should the main field require less space we could make the teazer winding "more cobby" by using 3 layers of conductors instead of 2.
