DC Permanent Magnet
Permanent magnet DC machine
Modelica Standard Library
The DC PermanentMagnet (or DC Permanent Magnet) component models a DC Machine with permanent magnets. Armature resistance and inductance are modeled directly after the armature pins, using an Air Gap DC model. Permanent magnet excitation is modeled by a constant equivalent excitation current feeding the air gap.
The following losses are modeled:
heat losses in the temperature dependent armature winding resistance
brush losses in the armature circuit
core losses (only eddy current losses, no hysteresis losses)
stray load losses
No saturation is modeled.
Support at which the reaction torque is acting
Positive armature pin
Negative armature pin
Optional thermal port
Rotor moment of inertia
Stator moment of inertia
Operational armature temperature
Use Support Flange
True (checked) means enable stator support
Use Thermal Port
True (checked) means thermal port is enabled
