Permanent-magnet magnetic gears have various advantages such as having low acoustic noise and being maintenance-free in comparison with conventional mechanical gears. Various types of magnetic gears have been introduced in previous papers. Of these, planetary permanent-magnet magnetic gears have higher transmission torque than other types. We compared two types of planetary magnetic gears. The first utilized a surface permanent magnet (SPM), and the second used an interior permanent magnet (IPM). We compared the transmission torque and eddy-current loss that occurred in these magnets.
