The rotating magnetic field is the key principle in the operation of induction machines.The induction motor consists of a stator and rotor.In the stator a group of fixed windings are so arranged that a two phase current, for example, produces a magnetic field which rotates at an angular velocity determined by the frequency of the alternating current.
A pulsejet engine is an air-breathing reaction engine that employs an ongoing sequence of discrete combustion events rather than one sustained combustion event. This clearly distinguishes it from other reaction engine types such as rockets, turbojets, and ramjets, which are all constant combustion devices. All other reaction engines are driven ...
A permanent magnet synchronous motor and reluctance motor requires a control system for operating (VFD or servo drive). There is a large number of control methods for synchronous machines, selected depending on the construction of the electric motor and the scope. Control methods can be divided into: [21] [22] Scalar control. V/f control ...
Problems associated with the design of the axial piston engine include high oil consumption, high fuel consumption, low rpm limit imposed by previously discussed frictional loads, low overall horsepower, mechanical complexity and complex machining methods needs to allow the engine to stand up to the loads imposed on the components. Additional ...
The D-627 had coaxial contra-rotating fans with a differential gearbox. [25] D-727 a variant for the commercial version of the An-70, [35] called the An-70T. A high-bypass turbofan engine, [36] the D-727 has a bypass ratio of 12.85. [3]: 59 The D-727 was also the powerplant for the Yak-46-1, the high-bypass turbofan version of the Yakovlev Yak ...
An ignition magneto (also called a high-tension magneto) is an older type of ignition system used in spark-ignition engines (such as petrol engines). It uses a magneto and a transformer to make pulses of high voltage for the spark plugs. The older term "high-tension" means "high-voltage". [1]
