An electric motor (1) with permanent magnets includes a rotor (4), on which permanent magnets are fastened (6), and a stator (2). The stator includes a stator structure and coils (5) installed on the stator structure. The stator structure is realized by an assembly of at least three independent stator elements (21), assembled on a baseplate (3) with no direct mechanical linkage between them. Each stator element (21) is fastened onto the baseplate (3) of the motor by an adjusted fastener (31) and at least one anti-rotation element (32). Preferably, the stator elements (21) are made of a material that is a good heat conductor and electrical insulator, such as a ceramic.
