Electrically, the connections seem fine, they just seem loose
mechanically. Is this normal?
This is a fairly common issue. If the connector doesn't totally fall
out, may not need to worry about it (yet).
I have run it on a 12V battery charger (capable of only 6A max), and
it runs fine, but seems to not have much torque
To get full torque, you need full field. And more than 6 amps on the
armature.
To test the E15 motor, I'd connect the field to 36 volts (only 2 or 3
amps needed). Then (and only then) connect the armature to 12 volts. As
in a 12 volt battery that can source 50+ amps.
If all good, then can try with the armature on 24 volts if you want to
see more power. Reducing the field to 24 or 12 volts will increase the
motor speed, but reduce torque.
