The three clock motors which were rewound and measured demonstrate that existing is about 300mA on common.
This motor hasn't been rewound - and it is probably not, since it is a good instance for demonstration into the attendees of the 'Electric Horology Brief Training course' that was run for NAWCC Chapter seventy two for the duration of 2008. As it looks probable the study course will run once more, I need demonstration motors.
