An actuating system for a primary flight control surface including unique electric drive motors having an integral detent mode. The motors include a unique laminated stator core and means for changing the continuity of the magnetic circuit. The stator core structure is split into two part-cylindrical elements which define air gaps between their opposing ends. Flux gates fill the air gaps and provide magnetic circuit continuity. The flux gates are connected to solenoids which can displace the flux gates in and out of the air gaps, thereby changing the continuity of the magnetic circuit of the motor. The motor rotor aligns its magnetic axis with the air gaps, and will resist substantial imposed torque loads. |
