Method for optimising the operation of an electric motor

The method involves determining peak voltage achieved during a braking phase in an energy storage unit (2). The peak voltage is compared with the regular allowable maximum voltage of the energy storage unit. The minimum voltage of energy storage unit is increased in deceleration phase of an electric...

Beschreibung
Zusammenfassung:	The method involves determining peak voltage achieved during a braking phase in an energy storage unit (2). The peak voltage is compared with the regular allowable maximum voltage of the energy storage unit. The minimum voltage of energy storage unit is increased in deceleration phase of an electric motor (1-2), if the peak voltage at energy storage unit is equal to or smaller than regular allowable maximum voltage of the energy storage unit.
