摘要： A motor for a pump is provided with a radially outer stator and a radially inner rotor. The radially outer stator having a laminated core. The rotor is mounted in two magnetic axial bearings distanced from one another in an axial direction of the rotor. A position of the stator relative to a reference surface, against which a component rests, is established exclusively by a single positioning element arranged between the laminated core of the stator and the reference surface. A stationary part of a first magnetic axial bearing of the two magnetic axial bearings is integrated in the component.

摘要： A high-speed permanent magnetic motor assembly generates a magnetic field to produce mechanical output power. The assembly comprises a motor, a motor housing, and a radial bearing block. A motor housing supports a rotor and the radial bearing block with a left radial aerostatic bearing, a right aerostatic bearing, and an axial thrust aerostatic bearing. The bearings are porous aerostatic bearings that use a low-viscous vapor-liquid two-phase fluid as a lubricant, which penetrates through a porous bushing. The liquid vaporizes from pressure reduction, and part of the liquid arrives at a clearance between each of the bearings and the rotor. The liquid of the two-phase fluid is vaporized during discharge along an axial direction from the bearing. This increases the vapor in the clearance, improve a bearing capacity, retain position accuracy of an aerostatic bearing, and cool the aerostatic bearings and the rotor.

摘要： An electric pump is provided, which includes a housing, a shaft, a rotor assembly and a stop assembly. The shaft is fixed to the housing, the rotor assembly is rotatable about the shaft, and the rotor assembly is sleeved on the shaft. The stop assembly is configured to limit the position of the rotor assembly in the chamber. The stop assembly includes a first stop and a second stop, the first stop is fixed with respect to a second portion of the shaft, and the second stop is fixed with respect to a first portion of the shaft. No relative movement occurs between the stop assembly and the shaft, which reduces the abrasion between the stop assembly and the shaft resulted from friction, and facilitates improving a service life of the stop assembly.
