SMART SUSCEPTOR FOR SHAPE MEMORY ALLOY ACTUATOR INDUCTIVE HEATING SYSTEM Russian patent published in 2018 - IPC F03G7/06 H01F41/02 

FIELD: machine building.

SUBSTANCE: disclosed system for heating a shape memory alloy (SMA) actuator may include an SMA actuator, a smart susceptor, a plurality of induction coils, and a control module. SMA actuator may have at least one layup. SMA actuator may be selectively heated to a transition temperature. Smart susceptor may be in thermal contact with the at least one layup of the SMA actuator. Induction heating coils may be configured to receive an alternating current and generate a magnetic field based on the alternating current. Magnetic field may create an eddy current in at least one of the SMA actuator and the smart susceptor to heat the SMA actuator to the transition temperature.

EFFECT: control module may be configured to drive the alternating current supplied to the induction heating coils.
