.Modelica.Electrical.Machines.Losses.DCMachines.StrayLoad .Modelica.Electrical.Machines.Losses.DCMachines.StrayLoadThe stray load loss torque is
tau = PRef/wRef * (i/IRef)^2 * (w/wRef)^power_w
where i is the current of the machine and
w is the actual angular velocity. The dependency of
the stray load torque on the angular velocity is modeled by the
exponent power_w.
The stray load losses are modeled such way that they do not cause a voltage drop in the electric circuit. Instead, the dissipated losses are considered through an equivalent braking torque at the shaft.
If it is desired to neglect stray load losses, set
strayLoadParameters.PRef = 0 (this is the
default).
