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)
|
No saturation is modeled.
