Lehner LMT motors (2230, 1940)

I was wondering what cell counts the Lehner 2230 and 1940 should be used at? I've also seen that there are 5 wires coming from the motors... does this mean that it is a 5 phase motor? What speed controls can be used with these motors and how do you wire them? Hoe much power increase compared to an Feigao XL motor? Sorry for all the questions,but the holidays are coming and I want to keep my options open :)
