Document Type and Number:
WIPO Patent Application WO/2019/186682
Kind Code:
A1
Abstract:
An electric motor (1) is provided with a rotor (2) having a first rotor core (21) and a second rotor core (22), and with a stator (3). The minimum distance (G1) from the first rotor core (21) to the stator (3) is smaller than the minimum distance (G2) from the second rotor core (22) to the stator (3). The maximum radius (Ra) of the first rotor core (21) is greater than the maximum radius (Rb) of the second rotor core (22). A first thin-walled section (205a) of the first rotor core (21) and a second thin-walled section (205b) of the second rotor core (22) have the same shape.
