RE: IEEE 112 Testing
In North America the electric motors are tested in accordance with IEEE 112, But you can find this methods: B,C,E,E1,F and F1.
In The F method is not neccesary to couple up the motor and a is necesarie to perform a Dual-Frecuency heat run and use
stray loads.
The F1 method use an assigned value to the load loss.

RE: IEEE 112 Testing
Basically in Method F, Stray Losses are measured, and in Method F1 are calculated or assumed!
Is that correct?
RE: IEEE 112 Testing
As Tommy007 said; On method F the stray-load loss is directly meassured. For method F1 stray-load loss is assumed
