Title:
VEHICLE DRIVE
Document Type and Number:
WIPO Patent Application WO/2011/098986
Kind Code:
A2
Abstract:
The invention relates to a vehicle drive that has an energy source (7) for the provision of electric energy and a synchronous motor (1), to which energy is supplied by the energy source (7) and which comprises a rotor (11), a stator (12) and at least one air gap (28). The rotor (11) has a first body (40) that can be magnetized, a second body (31) that can be magnetized and a third body (32) that can be magnetized, a first magnetizing element (510) and a second magnetizing element (520). The first body (40) and the second body (31) extend radially in such a way that the first magnetizing element (510) lies axially (a) between the second body (31) and the first body (40) in order to magnetize said first (40) and second bodies (31). The first body, second body and third body each have air gap surfaces (43, 39) for conducting a magnetic flux through the air gap (28) to the stator.
