This paper provides computer analysis and experiential investigation of the permanent magnet machines with neodymium ferrite magnets to discuss feasibility utilizing induction machines-oriented equipment for PM machine production. For this purpose, are obtained by replacing squirrel-cage rotor motor flux-focusing (tangential) surface-mounted (radial) rotors. Electromechanical parameters as elec...

In contrast to conventional generators, self-excited induction generators are found to be most suitable machines for wind energy conversion in remote and windy areas due to many advantages over grid connected machines. This papers presents a Self-Excited Induction Generator (SEIG) driven by wind turbine and supplying an induction motor which is coupled to a centrifugal pump. A method to describ...

Single-phase induction machines are found in various appliances such as refrigerators, washing machines, driers, air conditioners, and fans. Large concentrations of single-phase induction motor loads such as air conditioners and other motorcompressor loads can adversely impact the dynamic performance of a power system. An understanding of the dynamics of this type of induction machine is needed...

most of the methods that have been proposed for speed estimation of induction machines require the rotor and the stator resistance to change in the normal operating range. on the other hand, estimation of the rotor resistance requires rotor speed. in this paper, after studying conditions for simultaneous estimation of rotor speed and rotor resistance, a method for simultaneous estimation of rot...

Induction machines play a vital role in industry and there is a strong demand for their reliable and safe operation. The online monitoring of induction motors is becoming increasingly important. The main difficulty in this task is the lack of an accurate analytical model to describe a faulty motor. Faults and failures of induction machines can lead to excessive downtimes and generate large loss...

Grid-powered pumping plants are widespread electromechanical systems commonly set in motion by electrical machines. The productivity of these varies substantially according to the shift location working point on H-Q plane, which is determined with help mutual positions characteristics pump unit itself and hydraulic parameters pipeline. topic proposed article mainly focused investigation plant e...
