Abstract
A two-speed magnetic gearbox includes a magnetic ring with first magnets distributed about an inner circumference forming first pole pairs, a magnetic sun including second magnets distributed about an outer circumference forming second plurality pole pairs, a first modulator arranged radially between the magnetic ring and the magnetic sun and a second modulator arranged coaxial with and axially offset from the first modulator. The first modulator is axially displaceable and includes a first plurality of electric steel laminations, and the second modulator is axially displaceable to a position radially between the magnetic ring and the magnetic sun and includes a second plurality of electric steel laminations. A quantity of second pole pairs is different than a quantity of first pole pairs and a quantity of the first plurality of electric steel laminations is different than a quantity of the second plurality of electric steel laminations.
