dc motor inrush current
Hi,
From a mathematical point of view, if you're only interested in a very rough model, you can describe both types of motors with similar equations (U=r.i + L.di/dt + K.EMF and Torque = K.i and EMF = K.speed). Both machines work in a similar way, the mechanical commutations of the brush motor being translated into electronic commutations of the inverter. However, if you're interested in the detailed electrical behavior of the motors, you'll have to implement a much more complex model.
I hope this helps,
Samuel
