Torsional compensator based on magnetic reluctance

A torsional compensator for an internal combustion engine, the torsional compensator comprising:

• a first rotor portion in driving engagement with an output of the internal combustion engine, the first rotor portion comprising at least one of a first magnetic array and a first ferromagnetic array;
• a first stator portion disposed about the first rotor portion, the first stator portion coupled to at least one of the internal combustion engine, a transmission, and a compensator housing, the first stator portion comprising at least one of a second magnetic array and a second ferromagnetic array;
• and
• a stator actuator in driving engagement with the first stator portion to change a rotational position of the first stator portion about an axis of the first rotor portion, wherein in response to rotation of the first rotor portion within the first stator portion, a magnetic reluctance force is generated, the magnetic reluctance force applying a torque to the output of the internal combustion engine to dampen a torque ripple of the internal combustion engine and in response to the change in rotational position of the first stator portion about an axis of the first rotor portion, a phase angle of the torsional compensator is adjusted.
