Abstract
The present invention provides a magnetically geared generator including an inner winding unit having a first number of pole pairs, an outer winding unit arranged coaxially around the inner winding unit and having a second number of pole pairs, and a rotatable magnetic flux modulator arranged coaxially between the inner winding unit and the outer winding unit. The inner winding unit, the outer winding unit and the rotatable magnetic flux modulator are adapted to convert rotational input energy provided at the rotatable magnetic flux modulator into electrical output energy provided as an alternating output current at one of the inner winding unit and the outer winding unit, and to control an output frequency of the alternating output current by communicating output energy as an alternating feedback current to the other one of the inner winding unit and the outer winding unit and by adjusting a feedback frequency of the alternating feedback current.
