Domains: Continuous. Size: 1-D. Kind: Iconic Diagrams (Electric, Electric).

Description - Default

This models represents an ideal DC-motor with no energy loss. The electric port has separate high and low terminals. The equations are

 

p1.i = p1_high.i = p1_low.i;

p1.u = p1_high.u - p1_low.u;

 

The model can have mixed forms of causality

 

p1.u = k * p2.omega;

p2.T = k * p1.i;

 

or:

 

p2.omega = p1.u / k;

p1.i = p2.T / k;

 

Interface - Default
