I need of your help; I have a lot of 400Hz Muirhead Servomotor-Tachometer generator mod. 15M81A, for 400Hz isn't a problem but I don't have acquaintance, idea and experience for drive and use this motors. This motor have a 115Vac primary and two 13Vac control windings, one tachometer 115 Vac primary and a secondary output.
