Abstract
A can of a drive motor is provided for a pump assembly, wherein the can (22) is manufactured at least partly of plastic (52). At least in a part of the can (22) the plastic (52) is reinforced by individual fibers (32) distributed in the plastic (52). The fibers (32) in at least one layer (35) of the can (32) are aligned in a defined manner in the peripheral direction with respect to the longitudinal axis (Z) of the can (22). A method for manufacturing such a can is also provided.
Claims11
A can of a drive motor for a pump assembly comprising:
- a cylindrical peripheral wall (30);
- and
- a closed base wall (27) at one axial end of the can,
- wherein the can (22) is manufactured at least partly of plastic (52) comprising at least a first layer (35) and a second adjacent layer (34, 36),
- wherein at least in a part of the can (22), the plastic (52) is reinforced by individual fibers (32) distributed in the plastic (52),
- wherein the fibers (32) in the first layer (35) are aligned in a defined manner in a peripheral direction with respect to a longitudinal axis (Z) of the can (22),
- wherein, in the peripheral wall (30), the fibers (32) in the second adjacent layer (34, 36) are aligned in an axial direction with respect to the longitudinal axis (Z) of the can (32), and
- wherein, in the closed base wall (27), the fibers (32) in the second adjacent layer (34, 36) are aligned in a radial direction with respect to the longitudinal axis (Z) of the can (32).
