초록

An electrically commutated motor for a fuel pump having a rotor connected to a shaft and having plastic-bonded ferrite, with a fuel-resistant shaped body formed by the plastic-bonded ferrite, and a magnetic return element adjustable in relation to the shaped body.

대표청구항 ▼

The invention claimed is: 1. An electronically commutated motor for a fuel pump, comprising a rotor which is connected to a shaft in a rotationally fixed manner and has a plastic-bonded ferrite, wherein the rotor has a fuel-resistant shaped body which is formed by the plastic-bonded ferrite, and a magnetic return element adjustable in relation to the shaped body by being moved on the shaft, with the shaped body having an axial recess in which the return element (14) engages, with the axial recess having an opening side and a base side which is situated opposite the opening side and at which the shaped body is connected to the shaft, and with the axial recess forming a funnel which widens conically toward the opening side, and in that the return element forms a cone which tapers toward the base side of the recess. 2. The motor as claimed in claim 1, wherein the funnel has an opening angle and the cone has an angle, and the funnel opening angle corresponds to the cone angle of the cone. 3. The motor as claimed in claim 1, wherein the plastic which bonds the ferrite is polyphenylene sulfide. 4. The motor as claimed in claim 1, wherein the shaped body has stabilizing fiber material. 5. The motor as claimed in claim 1, wherein the shaped body is injection molded onto the shaft, and in a connecting region between the shaft and the shaped body, the shaft has a pattern which increases surface roughness of the shaft. 6. The motor as claimed in claim 1, wherein the return element is adjustable in relation to the shaped body by being moved on the shaft. 7. The motor as claimed in claim 2, wherein the plastic which bonds the ferrite is polyphenylene sulfide. 8. The motor as claimed in claim 2, wherein the shaped body has stabilizing fiber material. 9. The motor as claimed in claim 2, wherein the shaped body is injection molded onto the shaft, and in a connecting region between the shaft and the shaped body, the shaft has a pattern which increases surface roughness of the shaft. 10. The motor as claimed in claim 2, wherein the return element is adjustable in relation to the shaped body by being moved on the shaft. 11. The motor as claimed in claim 3, wherein the shaped body has stabilizing fiber material. 12. The motor as claimed in claim 3, wherein the shaped body is injection molded onto the shaft, and in a connecting region between the shaft and the shaped body, the shaft has a pattern which increases surface roughness of the shaft. 13. The motor as claimed in claim 3, wherein the return element is adjustable in relation to the shaped body by being moved on the shaft. 14. The motor as claimed in claim 4, wherein the shaped body is injection molded onto the shaft, and in a connecting region between the shaft and the shaped body, the shaft has a pattern which increases surface roughness of the shaft. 15. The motor as claimed in claim 4, wherein the return element is adjustable in relation to the shaped body by being moved on the shaft. 16. The motor as claimed in claim 5, wherein the return element is adjustable in relation to the shaped body by being moved on the shaft. 17. The motor as claimed in claim 7, wherein the shaped body has stabilizing fiber material. 18. The motor as claimed in claim 17, wherein the shaped body is injection molded onto the shaft, and in a connecting region between the shaft and the shaped body, the shaft has a pattern which increases surface roughness of the shaft. 19. The motor as claimed in claim 18, wherein the return element is adjustable in relation to the shaped body by being moved on the shaft.
