METHOD OF CONTROLLING PRIMARY MAGNETIC FLUX Russian patent published in 2017 - IPC H02P21/00 H02P6/16 H02P27/06 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering and can be used to control a synchronous motor with permanent magnets. In compliance with the method of controlling the primary magnetic flux in accordance with the torque changed is the value of the primary magnetic flux command in accordance with the torque for proper control due to that over the current phase at control over the primary magnetic flux. With regard to certain torque T in cases when the amplitude of the Λδ primary magnetic flux takes the value of Λδ0(T), amplitude ia of the anchor current is minimized. Herewith provided is control with maximum torque/current. Thus, the value of Λδ0(T) is used as the amplitude of the value of the primary magnetic flux command to control over the primary magnetic flux, owing to which the anchor current is determined automatically. I.e. current phase β is defined unambiguously. One word, control over current phase β is carried out in order to obtain the desired phase according to torque T, for the rotary motor to be driven into action in the effective operating point in accordance with the torque.

EFFECT: technical result is actuation of the rotary electric motor in the effective operating point.
