| Zusammenfassung: | A technique for establishing a value of a rotor parameter indirectly is provided. The rotor parameter may be electrical resistance of the rotor, rotor temperature, rotor current, rotor torque, etc. The technique may comprise obtaining other motor data and data obtained during operation of the motor directly and then using an algorithm to establish an estimated value of the rotor parameter. A system for establishing an estimated value of a rotor parameter also is provided. In addition, an electric motor having a system that is operable to establish an estimated value of a rotor parameter is provided. |
