This was bolted straight to the top from the five-bearing crank through the hub of 1 pole. The other pole experienced an open up stop to obtain the stator winding. The outer deal with also held the 3-period stator windings. The magnetic circuit had two auxiliary air gaps amongst the rotor and its stationary core. The regulator was a conventional automotive kind with vibrating points. Mainly because it experienced no slip rings, it was very compact and rugged, but due to the auxiliary air gaps, it experienced inadequate efficiency. By range of phases[edit]
