METHOD TO CONTROL THREE-PHASE VALVE ELECTRIC MOTOR OF IMPLANTED ROTARY ELECTRIC PUMP OF CARDIOPROSTHESIS WITH PROVISION OF LIVENESS PROPERTY (VERSIONS) Russian patent published in 2014 - IPC H02H7/09 H02P6/12 

FIELD: electricity.

SUBSTANCE: by a signal from current sensors, a failure is detected in a chain of one of three phases of an anchor winding. Then by means of a microcontroller device a signal is sent for actuation of a protective element of the failed phase, the process of automatic switching of two operating phases is carried out, providing for development of a motor torque. The protective element is represented by power switches of that inverter stand, to which the failed phase is connected. Remaining switches, forming a single-phase bridge inverter, are switched by means of a microcontroller device, carrying out serial selection of previously recorded control codes from memory cells corresponding to the condition of the anchor winding and position of the rotor. The criterion of available fault, as well as sound and light signals announcing the available fault and time of its occurrence, are generated by means of the microcontroller.

EFFECT: development of the method to control a three-phase valve electric motor of an implanted rotary electric pump of a cardioprosthesis with provision of liveness property, which provides for realisation of liveness property of a three-phase valve electric motor, comprising one three-phase bridge inverter and having only three outputs from an anchor winding connected as star.
