Induction motors are widely used in the industry due to its relative low cost, low maintenance and high reliability. The development of the computer and electronic industry, as well as design of new control methods, has opened the door to control induction motors. In order to control the induction motors, scalar and vector control methods are used. Vector methods have faster response and more p...

The ability to monitor the condition of an electrical machine has been a concern of industry for many years. Knowing when a machine requires maintenance allows users to perform the required maintenance at their convenience, rather than during costly unscheduled shutdowns. This need for improved industrial monitoring techniques has produced a number of studies on the detection of mechanical faul...

This paper uses the flux-MMF diagram to compare and contrast the torque production mechanism in seven common types of electric motor. The flux-mmf diagram is a generaked version of the flux-linkage versus current (+i) diagram €or switched-reluctance motors. It is illustrated €or switchedreluctance, synchronous-reluctance, induction, brushless ac, brushless dc, interior PM and dc commutator moto...

The energy efficiency of machines is nowadays an intensively studied problem. the induction motor dominantly influenced by rotor’s and stator winding’s temperature. main goal research presented in this paper to develop a methodology based on Computational Fluid Dynamics (CFD) analysis internal external aerodynamics, which necessary for optimisation cooling motors. In paper, theoretical, as well...
