<p>PROBLEM TO BE SOLVED: To provide a rotary electric machine equipped with a planetary roller mechanism to reduce a required amount of lubricant oil.SOLUTION: A rotary electric machine 100 includes: a rotor 3 having a cylindrical peripheral wall 3aa incorporating a permanent magnet 4 along a circumferential direction; and a stator 2 provided outside of the peripheral wall 3aa of the rotor 3. The rotary electric machine 100 further includes: a planetary roller 6 that is rotated by a transfer of the rotation of the rotor 3 transferred from the peripheral wall 3aa to an outer peripheral surface 6aa; an output axis 9 that is provided inside the peripheral wall 3aa and is rotated by a transfer of the rotation of the planetary roller 6 transferred through the outer peripheral surface 6aa; and magnetic oil 20 having magnetism and being introduced in the inside of the peripheral wall 3aa, in a planetary roller mechanism chamber 3d inside the peripheral wall 3aa.</p> |
