RESOLVER WITH MOUNTING STRUCTURE AND METHOD

摘要

An apparatus including a rotating member, a resolver and a mounting structure. The resolver includes a resolver stator and a resolver rotor fixedly mounted on the rotating member via a mounting structure. The mounting structure has a low magnetic relative permeability and isolates the resolver rotor from the rotating member by preventing direct contact between the rotating member and the resolver rotor. The disclosed apparatus may be an electric machine having a rotor fixed to the rotating member and be suitable for use in a hybrid vehicle. The mounting structure advantageously has a relative permeability of no greater than about 2 and may be formed out of stainless steel material. The rotating member may be a rotor hub formed out of steel material having a relative permeability of at least about 50.
