I have a tangental but related question to this post's topic.
I am retrofitting a 2 wire, 800 watt permanent magnet windlass for a 3 wire, 1000w series wound windlass.
The 2 wire windlass has existing 25-ft, 2 AWG wire runs. The new windlass calls for a larger wire gauge (1 or 1/0awg).
If I understand the series wound motor
correctly, one of the two positive posts is dedicate to "down" and one to "up".
So as "down" presumably uses a lot less current
than "up", I thought I would leave the existing 2AWG wire for the "Down" pole and replace the negative (common) pole and the "UP" pole with larger gauge wires.
Or am I misunderstanding how a series wound motor
works and the relative current
draw through each of the three wires?
