Growlers will work on any armature where the coil can be isolated … foldable shopping cart on wheelsIn electrical engineering, the armature is the winding (or set of windings) of an electric machine which carries alternating current. The armature windings conduct AC even on DC machines, due to the commutator action (which periodically reverses current direction) or due to electronic commutation, as in brushless DC motors. The armature can be on either the rotor (rotating part) or the stator (stationary part), depending on the type of electric machine. egg on twitterhttp://whitelegg.com/products/electric-motor/electric-motor-rewind-and-repair/gr3-4-armature-growlers foldable shopping cart home depotWebModel GR1 for a 110v single phase power supply.
