Magnetically suspended fluid pump for control or regulation system

摘要

The pump has a hollow stator part, a rotor part mounted in the stator part, a magnetic suspension with stator and rotor magnet parts carried by the stator and rotor parts to hold the rotor part radially in the rotor chamber with an annular magnetic suspension gap between inner and outer wall parts, a magnetic drive and a Lorenz force axial bearing. Independent claims are also included for an arrangement for driving the pump, a method of operating the pump and a heart support system.
