Slip adjuster for use in electrical motor controllers |
摘要 |
A system for accurately determining a slip frequency for use in controlling an induction motor. The system includes two tables for determining ideal flux and flux current levels as a function of rotor speed and uses values from those tables to determine an actual rotor inductance required for calculating the slip. The system also generates a slip multiplier which is used to increase or decrease the slip as a function of the flux current to compensate for changing rotor resistance.
