Efficiency of Lehner motors

[Hayden]

Does anyone know what the Efficiency of the Lehner motors are?
Does it vary from size or kv of the motor?
I think every model of motor is different they will have a different sweet spot where it has its max efficiency at a certain rpm...etc..

[Sylvester]

The sweet spot for lehners are around 35K.. I think they are 85% efficient under partial load, maybe Rene or somebody else could scope in on this.

[Hayden]

I think their over 90% efficient but I could be wrong
I think that’s one of the reasons why lmt motors are so expensive

[Sylvester]

They are very efficient. They are expensive for several other reasons ;

Hand wound
Segmented magnets
Made id Germany :)

GERMAN ENGINEERING IN DA HOUZZZE! ;)

Efficiency will vary a bit. Factors include voltage, wind, load, etc. I imagine the efficiency range for our use will range from 60%-90% with the Lehner motors.

[Hayden]

I was referring to the efficiency % that they state in the specifications so I can compare motors.
Isn’t it the efficiency that counts mostly?

If these lehner motors are so good (and they are!!!) why don’t they supply specification with them? When I got mine and I just got the motor in a tube and that’s it:030:

Nope, efficiency is one thing, but it needs to be at a certain load.

I guess it is not clear how to use my program...

This is measured data, not calculated.

Measured only key motor parameters, the rest is calculated as well.

I randomly clicked one of the 1940 specs and efficiency was 91%...damn.

I have got no idea what you mean.

[BrianG]

I want a 110% efficient motor...

[Serum]

Good point, we don't need a superconductive controller to get to a 100 percent total efficiency that way..

111 here.
