DEVICE TO ESTIMATE SYNCHRONOUS MOTOR PARAMETRES Russian patent published in 2010 - IPC H02P7/06 

FIELD: engines and pumps.

SUBSTANCE: proposed device comprises synchronous motor, its parameters to be estimated, transducer of longitudinal current and its derivative, shaft rpm transducer, longitudinal voltage transducer, transducer of transverse current and its derivative, transducer of angular acceleration and motor shaft turn angle, multipliers, adders, scalers and integrators. Adding of transducers of longitudinal voltage, transverse current and its derivative, angular acceleration and motor shaft turn angle, five adders, twelve multipliers, five scalers and three integrators, allows producing device that can generate additional estimates of transverse inductivity, magnetic linkage, moment of inertia and static moment of load without notable complication of the device. Application of said device in automated synchronous electric drive allows modular or adaptive control.

EFFECT: enlarged number of estimated parameters.
