Abstract
The present disclosure relates to a media gap motor for a turbocharger. The proposed media gap motor contains a rotor and a stator, wherein the stator comprises multiple fins which extend from an inner portion radially towards the rotor in a flow chamber formed between the stator and the rotor. The fins do not extend as far as the rotor, and therefore a gap is formed between an inner end of the fins and the rotor, wherein in internal diameter of the fins is at least 1.2 times and at most 3 times an external diameter of the rotor.
Claims28
A media gap motor for a turbocharger, the media gap motor comprising:
- a rotor;
- and
- a stator, surrounding at least a coaxial portion of the rotor, the stator comprising:
- multiple stator fins that extend from an inner portion of the stator radially towards the coaxial portion of the rotor in a flow chamber formed between the stator and the coaxial portion of the rotor, wherein the multiple stator fins do not extend as far as the coaxial portion of the rotor, and therefore a gap is formed between an inner end of each of the multiple stator fins and extending circumferentially about the coaxial portion of the rotor, and wherein an internal diameter of each of the multiple stator fins is at least 1.2 times and at most 3 times an external diameter of the coaxial portion of the rotor.
A turbocharger for an internal combustion engine, comprising:
- a compressor arrangement for compressing fresh air;
- a compressor wheel;
- and
- a media gap motor, the media gap motor comprising:
- a rotor;
- and
- a stator, surrounding at least a coaxial portion of the rotor, the stator comprising:
- multiple stator fins that extend from an inner portion of the stator radially towards the coaxial portion of the rotor in a flow chamber formed between the stator and the coaxial portion of the rotor, wherein the multiple fins do not extend as far as the rotor, and therefore a gap is formed between an inner end of each of the multiple stator fins and extending circumferentially about the coaxial portion of the rotor, and wherein an internal diameter of each of the multiple stator fins is at least 1.2 times and at most 3 times an external diameter of the coaxial portion of the rotor, and wherein the rotor is coupled to the compressor wheel.
A media gap motor for a turbocharger, the media gap motor comprising:
- a rotor;
- and
- a stator, surrounding at least a coaxial portion of the rotor, the stator comprising:
- multiple stator fins extending from an inner portion of the stator radially towards the coaxial portion of the rotor in a flow chamber formed between the stator and the rotor, wherein the multiple stator fins do not extend as far as the rotor and therefore a gap is formed between an inner end of each of the multiple stator fins and extending circumferentially about the coaxial portion of the rotor, wherein an internal diameter of each of the multiple stator fins is at least 1.2 times and at most 3 times an external diameter of the coaxial portion of the rotor, wherein each fin of the multiple fins comprise an outer portion extending radially outside the flow chamber, and wherein the stator comprises multiple coils surrounding the outer portions of the multiple fins.
