[TowerTalk] Motor leads for CDR44?

[K0FF]

Gary let me reply to your question this way:
on the Bell type rotors the motor leads are: 1,3, 4 and 8.

2 is the brake and 3&7 are the pot leads.

Current from (let's say the right) switch goes out of the control box on pin
5 all the way down to the rotor, through the winding and back via the common
lead pin 1> At the same time the motor phase current has to come all the way
back to the box on pins 8 and 4 because the motor capacitor is in the box.
That makes 4 full runs of wire that the current must go through.
If you have a voltage sag problem, just remove the capacitor from the box
and put it at the rotor (That's what I did in an outdoor box).

The heavy leads still need to be on 1 (com) and 2 (brake) though, for the
brake draws a lot more than the motor does.

Happy Building, Geo>KØFF
