    Repairing small universal motor - dipping?

    For an application such as this I would try to obtain and use "bonding-wire". I dont want to appear to be endorsing or advertising so try a web-search. Forgive me if you are already aware of the fact but its vital to wind the coil with a wire/wires of the same diameter and with the same number...

    Retaining sleeve for rotor magnets

    Does the retaining sleeve have to be metalic? Why not use a "Resiglass" type self-amalgamating banding tape such as that used to retain armature and rotor windings? Its non-conductive, has zero magnetic influence and therefore shouldnt effect Kt.

    Dynastarter Question

    Dynostarts are not to be confused with traditional "series" type starter-motors. Hope this link helps. http://www.s109316956.websitehome.co.uk/vire7/How_To/Electrical/electrical.html http://www.s109316956.websitehome.co.uk/vire7/How_To/Electrical/electrical.html

    Heat around the drum at the lead end, this will melt the sealant and expand the metal, then tap and I say tap, the shaft at the non-lead end. If the drum is rubber coated it will have to be removed prior to applying the heat.

    36 pole induction motor

    Is physical size a factor? lets hope not.... .a 36-pole 55kw induction motor is going to be quite a substantial and very heavy item. As a guide here in IEC land a 55kw 8-pole requires a 315 frame.

    Funny nameplate

    Skoggs? What is the concern exactly? It would appear to be a typical nameplate from a European manufacturer. They way I read it, it is a 3ph 1.5kw dual-voltage machine, 2 pole at 60hz, suitable for 220v or thereabouts if connected in star, likewise 440v if conected in delta. Current ratios are...
