摘要： A gas transfer machine for use as a vacuum pump, for example, has a pump rotor mounted on a rotatable shaft for transferring a gas, and a reluctance-type motor for rotating the rotatable shaft. The reluctance-type motor has a stator, a motor rotor surrounded by the stator, and a shield member isolating the stator from the motor rotor. The motor rotor is directly coupled to the rotatable shaft and has a plurality of magnetic salient poles.

摘要： A screw pump includes a casing having inlet and outlet ports and a pump rotor rotatably mounted in the casing and having screw threads communicating with said inlet and outlet ports. The pump rotor is rotated by a reversible speed-controllable motor, typically a DC brushless motor, mounted in the casing to deliver a liquid such as a chemical solution from the inlet port through a liquid passage defined by the screw threads to the outlet port.
