(ET) Shunt or series

[Chris Zach <czach computer org>]

Quick question: Is the motor on the snow blower a series motor or a 
shunt wound one?

I'm curious because I noticed that after plowing this morning the plow 
refused to spin up. Just a little grunt and nothing. The chute was 
clear, as was the auger. The reset button was not out.

I realized the problem was the batteries were low to the point where the 
motor probably couldn't get it's field up and going to start the 
armature. So I drove it down to the outlet, charged, and everything was 
fine.

Odd.
