This was bolted directly to the end of the five-bearing crank through the hub of one pole. The other pole experienced an open stop to acquire the stator winding. The outer deal with also held the 3-stage stator windings. The magnetic circuit experienced two auxiliary air gaps concerning the rotor and its stationary Main.
