Abstract
An example electric turbocharger may include: a rotating shaft; a motor including a rotor fixed to the rotating shaft, and a stator; a motor casing housing the motor; a compressor casing including a scroll flow passage; a diffuser plate located between the motor casing and the compressor casing, a heat dissipation member located between the diffuser plate and the stator; and a seal located between the diffuser plate and the stator and located between the heat dissipation member and the rotating shaft.
Claims20
An electric turbocharger comprising:
- a rotating shaft;
- a motor including a rotor fixed to the rotating shaft, and a stator;
- a motor casing housing the motor;
- a compressor casing including a scroll flow passage;
- a diffuser plate located between the motor casing and the compressor casing,
- a heat dissipation pad located between the diffuser plate and the stator;
- and
- a seal located between the diffuser plate and the stator and located between the heat dissipation pad and the rotating shaft.
An electric turbocharger comprising:
- a motor including a rotor and a stator;
- a rotating shaft configured to be rotated by driving the motor;
- an impeller fixed to the rotating shaft;
- a compressor casing housing the impeller;
- a diffuser plate fixed to the compressor casing;
- a heat dissipation layer located between the diffuser plate and the stator;
- and
- a seal located between the diffuser plate and the stator in an axial direction of the rotating shaft,
- wherein the seal is located between the heat dissipation layer and the rotating shaft in a radial direction of the rotating shaft to restrict passage of gas, and
- wherein the seal is spaced apart from the heat dissipation layer.
An electric turbocharger comprising:
- a motor including a rotor and a stator;
- a rotating shaft configured to be rotated by driving the motor;
- an impeller fixed to the rotating shaft;
