摘要： A rotor (1) for an electric machine, in particular a permanently excited synchronous machine. At least one recess (20) is formed on the outer wall (12) of the receiving space (6) and forms a non-magnetizable space (29) adjacent to the lengthwise surface (10) of the permanent magnet (7). Due to this non-magnetizable space (29), iron losses in the stator teeth can be reduced in particular during operation of the electric machine in the field weakening range, which may result in a rise in efficacy of up to 3% for the electric machine.

摘要： The invention relates to an electric asynchronous machine (1), in particular an induction machine, comprising: —a cylindrical stator (2) with stator teeth (22) on a stator yoke (21), wherein a ratio between a yoke height (hy1) of the stator yoke (21) in the radial direction and a groove height (hn1) of the stator grooves (23) in the radial direction ranges from 1.75 to 2.5; —a cylindrical rotor (4) with poles (42) on a rotor yoke which are defined by short-circuit windings in a rotor body (41), wherein a ratio between the yoke height of the rotor body (41) in the radial direction and the groove height of the rotor grooves in the radial direction ranges from 2 to 2.75.

摘要： The invention relates to an asynchronous machine (1) as can be used particularly in electric vehicles or hybrid vehicles. The asynchronous machine (1) has a rotor (5) and a stator (3). The asynchronous machine is designed and controlled in such a manner that it has a pole pair number p of p=3. Because of the reduced yoke saturation that can consequently be achieved, the stator yoke (9) can be designed with a lesser height hy1, such that a ratio of the outer rotor diameter D2a to the outer stator diameter D1a can assume values between 0.7 and 0.8. As a result, enlarged rotor teeth (19) and correspondingly enlarged rotor grooves (21) can be formed in the rotor (5), such that electrical losses in the material in the rotor grooves (21) acting as the rotor coil element (23) are smaller in comparison to conventional asynchronous machines. The electrical losses occurring to a greater extent in the stator (3) compensating for this lead to a lesser warming of the stator (3) than would be the case with the rotor (5) as the stator (3) can be cooled by simple means. Overall, a higher continuous torque can thus be achieved with the asynchronous machine (1) according to the invention.
