| abstract | An electric motor, in particular a small-sized DC electric motor, having a rotor and a stator, wherein the stator comprises a permanent magnet magnetized in at least one magnetization direction and at least one ferromagnetic sleeve body disposed within the permanent magnet, and wherein the rotor is coaxial within the sleeve body rotating rotor shaft, wherein the sleeve body (3) formed as an inner yoke and the permanent magnet is arranged on the sleeve body, wherein the wall thickness of the sleeve body is dimensioned such that at a given volume and given material of the permanent magnet (2) in the sleeve body (3) generated magnetic flux density is below the saturation polarization of the sleeve body (3), wherein the wall thickness D IR of the sleeve body (3) in the plane which is perpendicular to the magnetization direction through the longitudinal axis (A) of the sleeve body, over the largest Te Its length, at least in the region of the permanent magnet, is formally measured as follows: is there R IR is the distance of the outer wall of the sleeve body from the longitudinal axis, B PM is the magnetic flux density in the permanent magnet, J SIR the saturation polarization of the sleeve body. |
