Information

This is an idealized angular speed controlled electric machine model. The actual angular speed of the electric machine can be adjusted by means of the signal input. Make sure that speed discontinuouties do not occur.

Fig. 1: Principle of controlled machine model without gear

The following variables are calculated in the model

Machine

aMachine = angular acceleration of machine
phiMachine = mechanical angle of machine
wMachine = angular velocity of machine
tauMachine = (electrical) torque of machine
powerMachine = power of machine

Notes

Electrical connections are not modeled. The machine will always drive at the controlled input speed.
In case of numerical issues, change parameter exact to false
