    2x LMT 1950/9 HiAmp with WK + "Aufschwinghalterung"

    Hello Guys,

    I want to offer a pair of LMT 1950/9 in the HiAmp Version with an improved Hopf ProLine Water Jacket as well as the original "Aufschwinghalterungen" from LMT. The cables will be made off, as I think nearly nobody here uses the 6mm LMT connector system.

    The engines are in good condition as well as the bearings. They are out of my HFK Prototype (Link) and have done a great job on 8S Lipo so far.

    Motors are for sale because I want to replace them with LMT 2240's.

    Price: 420€ + shipping

    Best regards,
    Manuel

          What are the kv with no load and how many watts are they rated continueos ? Thanks...

              Well I don't know the unloaded kv but I think its a bit above 1500kv, if interested I'll measure it for you. The rpm for LMT engines are given at their point of maximum efficiency. So for the 1950/9 and 28V its max. efficiency is at about 73Amps which means about 2kW output at the shaft.

              Is that sufficient?

                  are these Delta or Wye adjust by user, or fixed ?

                  One thing I have never found is max rated rpm for Lehner .. ?

                  thanks

                      Hello Wayne,

                      these are Delta-engines. Changing to Wye is theoretically possible but I wouldn't recommend to try unless you have the knowledge and soldering skills. These motors have got a max. rpm of about 50.000, the newest version of LMT 19 series can be used up to 85.000rpm (max. possible rpm according to the datasheet).

                      Best regards,
                      Manuel
