House Heating System
Model a simple house heating system. The model contains a heater, thermostat, and a house structure with four parts: inside air, house walls, windows, and roof.
Motor Thermal Circuit
How the thermal behavior of a brushless servomotor can be simulated using a lumped parameter model. Heat generated due to power losses in the stator iron stack, stator winding and rotor is represented by three heat flow sources: stator iron losses (Q_Iron), winding power losses (Q_Wind), and magnetizing and eddy current rotor losses (Q_Rotor). The losses were recorded during a motor typical cycle simulation and stored in the motor_losses.mat file. The motor thermal circuit is built of thermal conductances, thermal masses, and convective heat transfer blocks, which reproduce heat paths in the motor parts: winding, stator iron, motor case, rotor, front and rear bearing plates, and motor mounting flange. The motor exchanges heat with the atmosphere through the case-atmosphere, flange-atmosphere, and rear plate-atmosphere contacts. The ambient conditions are simulated with the ideal temperature source set to 300 K.
Heat Conduction Through Iron Rod
How thermal blocks can model a long iron rod that is fixed to a hot base at one end and exposed to air along its length and at its free end. The rod is an extended surface that undergoes conduction along its length and convection with air in the direction perpendicular to its length. Extended surfaces are often used as fins to cool a solid.
