CONTROL DEVICE OF SYNCHRONOUS MACHINE WITH PERMANENT MAGNETS Russian patent published in 2015 - IPC H02P21/00 H02P21/12 H02P6/12 H02P6/18 H02P27/06 

FIELD: electricity.

SUBSTANCE: invention relates to the field of electric engineering and may be used to control a synchronous machine with MSAP permanent magnets. The control device of the synchronous machine with MSAP permanent magnets contains a sensor to receive a measured rotor position θ_m, facilities to control an operating point of MSAP machine depending on the rotor position and preset parameters, facilities to evaluate $$\widehat{\theta }$$ rotor position in an evaluation system of Park coordinates δ-γ related to the rotor. The above facilities for control (23) contain correction facilities (61) to adjust the above evaluated position $$\widehat{\theta }$$ of the rotor in compliance with the above measured position θ_m of the rotor, a fault detector for the above sensor and a switch designed to connect the control facilities to the sensor in order to receive the measured position θ_m of the rotor until the fault detector signals any fault of the above sensor or to connect the control facilities to evaluation facilities in order to receive the evaluated position $$\widehat{\theta }$$ of the rotor when the fault detector signals the fault of the above sensor.

EFFECT: optimal reliability and high safety.
