Technically you could get away with using 3mm? connectors on the motor wires so they mate up with the MM without having to change its plugs, but I would recommend 5.5mm, or 4mm gold plugs. Changing them over is a piece of cake; if I can do it anyone can.

1. heat plug up unitl solder melts, remove existing plugs.

2. Stand 5.5mm plug on tis end, and heat it up.

3. Poke silver solder into it until it melts, and fill it up.

4. Keep iron in place, and poke wire into the plug& molten solder- remove iron.

5. Hold wire in place until solder hardens.

6. Cover exposed female connector with heat shrink, job done.

There is a good video on youtube that shows exactly how to do this, but its a very simple job.

As for the Star/Delta thing:

For y-connection the three dd solder joints with a soldering iron must be isolated and be bridged instead of its the three s-s-connections with tin solder. In y-connection the engine works, as if it would have the 1.73-fache number of turns. E.G.: Type 1920/10 D corresponds to about 1920/17 S. Basic interconnecting and the number of revolutions list correspond to the Dreieckschaltung(D D are bridged).

Slightly gibberish, but with the diagram in this link you get the idea:

I get confussed when everyone says 3 or 5mm connectors when there 3.5 and 5.5. Any theres no wire on the back right? it just 5.5mm plugs on the back? And how would the 3.5mm fit in the bigger 5.5mm? I dont want to hard wire it if i dont have to. Easy for cleaning.
