Abstract
An electric machine arrangement, with two electric machines, each with a housing, wherein each housing has a machine space with a rotor-stator assembly and a resolver space section forming part of a resolver space that is formed between the machine spaces and is sealed off from the machine spaces. The housings are interconnected with their resolver space sections adjoining each other and complementing each other to form the resolver space. Several pressure equalizing elements are provided, and between the resolver space and at least one of the adjoining machine spaces, a pressure equalizing element is arranged, so that the pressure equalization occurs between the resolver space and the coupled machine space.
