Hey you, electric motor expert!
One of the “raisons d’être” of the Elektor Labs website is to help people advance with their projects. When posting a project, a special SOS badge can be activated when help from other users is solicited. This SOS project, all the way from New Zealand, is about restoring a lathe to which the poster would like to add a motor controller with self-excited capacitor/DC-injection braking. If you are into electric motors and motor controllers, this might be an interesting read. Maybe you can help with your expertise?
