Re: [amsat-bb] 24 Volt Motor theory help needed

["kc6uqh" <kc6uqh@xxxxxxx>]

Andrew,
The common method uses a 2 phase motor. This requires 24 VAC and a capacitor 
to shift the phase. The motor has two windings with one wire common to both 
windings. 24 volts is applied to the common winding and the other side 
connects to one winding and to the other winding with the capacitor in 
series. the direction of rotation depends on which of the two windings 
connects to the capacitor. The type of switching cricuit used can be 
simplified by using a 24-0-24 type of transformer, but it is not necessary.
