Information

This is an idealized torque controlled electric machine model. The actual torque of the electric machine can be adjusted by means of the signal input.

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

This machine model considers the following effect:

• Optional field weaking is considered by
• • the maximum torque of the machine, tauLimit for w ≤ wBase
  • the base speed limit wBase
  • torque reduction proportial to wBase/w for w > wBase
