Abstract

An electric machine having a stator body and a machine housing is provided. The stator body includes a stator ring of generally annular shape and a plurality of stator teeth projecting radially inward. A first bolt hole is defined in either the stator ring or machine housing, and a first receptacle is defined in the other and is coaxial with the first bolt hole. A second bolt hole is defined in either the stator ring or machine housing, and a second receptacle is defined in the other and is coaxial with the second bolt hole. A first counter bore is coaxial with the first receptacle. A first hollow dowel is mated to the first counter bore and the first bolt hole, and defines a first dowel hole, which is coaxial with the first counter bore and the first bolt hole.
