The stator and rotor both are the parts of the electrical motor. The significant difference between the rotor and the stator is that the rotor is the rotating part of the motor whereas the stator is the stationary part of the motor. The other differences between the stator and rotor are shown below in the comparison chart.

The shape of the axle lets you position independently both cranks and spider or Direct Mount, and thereby change the …
Twin screw compressors are positive displacement machines commonly used in industrial applications. Due to constraints of conventional manufacturing techniques these are usually produced with helical rotors of uniform pitch. However, other twin screw machines, such as vacuum pumps more often use variable pitch rotor for improved efficiency.

The invention achieves the above and other objects by providing a coaxial twin-rotor type helicopter in which an upper rotor and a lower rotor disposed on the same axis are rotated in opposite directions, said helicopter comprising: an airframe, a vertical shaft that rotatably supports the rotors, and a control mechanism that, with respect to a gravitational force direction, can tilt …
Tandem rotor helicopters have two large horizontal rotor assemblies mounted one in front of the other. Currently this configuration is mainly used for large cargo helicopters.. Single rotor helicopters need a mechanism to neutralize the yawing movement produced by the single large rotor. This is commonly accomplished by a tail rotor, coaxial rotors, and the NOTAR systems.
Sep 18, 2017· The concept of digital twins is not new. Digital twins refer to the digital representation of physical objects, and for more than 30 years, product and process engineering teams have used 3D renderings of computer-aided design (CAD) models, asset models and process simulations to ensure and validate manufacturability. NASA, for example, has run …
Aug 19, 2006· A slow-to-start rotor can lead rapidly to a roll inverted and impact with the ground. Reduced rotor flow in a roll can slow one rotor if you don't take precautions.
