My snow blower motor had a small shunt winding.  This speed limiting

snow blower.
True, it's not really a series motor. Technically it's a compound motor. Likewise the E20 motor is not really a shunt motor, it's a compound motor as there is a small field in series with the armature. That's why the motor runs a bit different in reverse than forward (the E15 is different).

apart.


I have had the tiller motor unload with the belt breaking. It did not come 
apart, explode, or whatnot. It just spun normally. If memory serves it is 
a series wound motor.

If there's enough interest I'll pull the gear and try running a lift motor 
at 36 volts unloaded. But with the gear on it just runs normally.
