Abstract
A synchronous electric motor with permanent magnets (). The synchronous electric motor includes a wound stator () having axially extending stator teeth () formed in a frame (), and a rotor () having a plurality of permanent magnets () extending axially in first recesses () of a cylinder head (). A dimensional ratio of a first outer diameter (D) of the rotor () to a second outer diameter (D) of the stator () is pre-determined so that the motor provides optimum efficiency. The dimensional ratio is pre-determined in such a way that the stator losses by Joule effect are reduced to a minimum. The synchronous electric motor is employed in electric compressors for motor vehicles.
