일 양태에서, 유체 역학 베어링을 포함하는 개선된 전기 트랜스미션 조립체가 제공된다. 상기 전기 트랜스미션 조립체는 외부 하우징의 내측에 배열된 고정자를 포함한다. 회전자는 상기 고정자에 의해서 회전 가능하게 구동되도록 구성된다 상기 회전자는 차동장치와 구동 가능하게 결합되도록 구성된 제1 기어를 갖는 회전자 샤프트를 포함할 수 있다. 상기 유체 역학 베어링은 회전자 샤프트와 외부 하우징 사이에 배열된다. 상기 유체 역학 베어링은 비-전도성 재료로 형성된다. 구체적으로, 상기 유체 역학 베어링은 중합체 재료 또는 플라스틱 재료로 형성될 수 있다. 일 양태에서, 상기 유체 역학 베어링은 비-금속 재료로 형성된다. In one aspect, an improved electric transmission assembly is provided that includes a hydrodynamic bearing. The electric transmission assembly includes a stator arranged inside of an outer housing. A rotor is configured to be rotatably driven by the stator. The rotor can include a rotor shaft having a first gear configured to driveably engage with a differential. A hydrodynamic bearing is arranged between the rotor shaft and the outer housing. The hydrodynamic bearing is formed from a non-conductive material. Specifically, the hydrodynamic bearing can be formed from a polymeric or plastic material. In one aspect, the hydrodynamic bearing is formed from a non-metallic material.
