· The rotor–stator rubbing is first observed in steam turbines around the 1920s since then, it became a challenging topic for many researchers. Newkirk and Taylor noticed that when a rotor rubs the stator below its first critical speed, the rub-induced lateral vibrations are amplified with the time. The phenomenon is named as “Newkirk effect.”
· A rotor-stator assembly was a high-speed homogenizer with a power consumption of 105 W and a generator consisting of 13 blades. The rotor has 9 blades 6 mm apart with a varying rotational speed of 1000−12000 rpm and a 0.5 mm gap between the outer rotor diameter and inner diameter.

· A separate starter unit is used to provide the first rotor motion, until the turbine’s rotation is up to design speed and can keep the entire unit running. The compressor module, combustor module and turbine module connected by one or more (Waste Heat Recovery Generator) for each gas turbine heats process water. The SGT-500 is a light
· A Texas-based, father/son team raised $4.5 million in seed funding to build "a remarkable electric motor technology," reports New Atlas. Long-time Slashdot reader Namarrgon writes Linear Labs' impressive new circumferential flux motor design uses four rotors [where other motors typically run one or two] and a software-reconfigurable, multi-coil stator, enclosed in a 3D magnetic "torque tunnel
Adopts in series mechanical seal, the material is the wear-resisting carbonization tungsten, featuring being durable, wear-resisting, can running for more than 8000 hours continuously safely. 4. The structure of the pump is compact, small, may move conveniently, installation is simple and convenient, it is submerged into the water, no need to build the pump house, reduce construction cost greatly.
· When the stator was driven by a voltage of 60 Vpp, the temperature stayed at 26 °C after a continuous running of 100 s. Even if the stator was driven by a voltage of 100 Vpp, the temperature of the stator rose by 15 °C after continually running for 10 min, then remaining stable afterwards. Therefore, the motor could work continuously without

The shape of the rotor and stator can be variable i.e. it might be improved or optimized. In practice the most common rotors are hemispheres as in Fig. 1, but what really matters is the diffusion angle of the gap between the rotor and the stator. One tip of the rotor’s shaft is fixed, so that the rotor can roll along the inner side of the
