Definitions
- the rotor blades can have asymmetrically different surfaces and / or angles of attack and thereby cause an asymmetrical flow on the rear wall of the pump.
- the drive itself can advantageously be designed in several variants.
- the drive rotor comprises an upper and a lower rotor disk, and the magnetic coils of the stator lie between these two rotor disks.
- the lower rotor disk of the drive can have a magnetic yoke in the form of a magnetically conductive disk or ring, for example made of soft iron.
- the coils can be arranged in several offset layers and / or wound at an angle to the plane of the coil body.
