blockTorqueLimiter
Torque limiter including field weakening
Information
This block enables a simplified approach of torque deduction due by field weakening. The field weakening behavior is characterized by:
- the maximum torque of the machine,
tauLimitforw ≤ wBase - the base speed limit
wBase - torque reduction proportial to
wBase/wforw > wBase
In this model the pull out torque behaviour is not considered.
