  • Contactless power transmission in an azimuth thruster
    Patent number: 11377184
    Abstract: A system for contactless power transmission in an azimuth thruster, the system comprising a first body (76) comprising at least one first inductor to provide a magnetic field, a second body (78) comprising at least one second inductor to generate an electrical current from the magnetic field, the bodies being configured to be relatively rotatable, the at least one first inductor and the at least one second inductor being configured to generate an electrical current from the magnetic field at all relative rotational positions, wherein the or each of the first inductors are tuned to resonate within a predetermined frequency band and the or each of the second inductors are tuned to resonate within a predetermined frequency band, the frequency band of the or each of the second inductors at least partially overlapping with the frequency band of the or each of the first inductors.
