Description

In this model bearing friction is represented as linear viscous friction. The model has only one initial port p defined. Because any number of connections can be made, successive ports are named p1, p2, p3 etc. 20-sim will automatically create equations such that the resulting torque p.T is equal to the sum of the torques of all connected ports p1 .. pn. The angular velocities of all connected ports are equal to p.omega. The model can have an torque out as well as an angular velocity out causality. In the last case the constitutive equation, as shown below, is simply inverted:

p.T = sum(p1.T, p2.T, ....)

p.omega = p1.omega = p2.omega = ....

Torque out causality:

p.T = d * p.omega;

Angular velocity out causality:

p.omega = p.T / d;
