Abstract
The motor provided includes a unique laminated stator core and a means for changing the continuity of the magnetic circuit. The stator core structure is split into two part-cylindrical elements which define spaces between their opposing ends. Flux gates fill the spaces and provide magnetic circuit continuity. The flux gates are connected to solenoids which can displace the flux gates in and out of the spaces, thereby changing the continuity of the magnetic circuit of the motor. The motor rotor aligns its magnetic axis with the spaces, and will resist substantial imposed torque loads.
