Test example: Investigate influence of armature temperature
on a DCPM motor
The motor starts at no-load speed, then a load step is
applied.
Beginning with the load step, the armature temperature rises
exponentially from 20 degC to 80 degC.
Simulate for 3 seconds and plot (versus time):
- dcpm.ia: armature current
- dcpm.wMechanical: motor's speed
- dcpm.tauElectrical: motor's torque
- thermalAmbientDCPM.Q_flow_a: motor's armature losses
Default machine parameters are used, but:
- The armature winding material is set to Copper.
- Armature reference temperature is set to 80 degC.
- Nominal armature temperature is set to 80 degC.
So the machine is at the beginning in cold condition, ending in
warm condition (with the same armature resistance as the unmodified
machine).
