Abstract
Provided is a magnetic strain wave gear device that makes it possible to achieve both improvement of the efficiency of assembly work and suppression of decrease in energy conversion efficiency. A magnetic strain wave gear device includes: a stator having a stator core, a stator winding, and a stator magnet; a first rotor; and a second rotor. The second rotor includes a second rotor core provided with a plurality of rotor magnet insertion holes and a plurality of rotor magnets inserted into the plurality of respective rotor magnet insertion holes. The first rotor includes a cylindrical first rotor core and a first rotor end plate. The first rotor end plate has a rotor magnet passage hole through which the rotor magnets can be inserted into the rotor insertion holes from outside in a direction of a rotation shaft.
