During the last decades, the rapid development of power semiconductor devices has allowed the increased use of adjustable speed ac drives in a variety of applications, especially in the process-control industry. In many applications, the capability of controlling the speed effectively can improve the efficiency of the ac motors and thus lead to large savings in energy. Among the several approac...

In this paper, with the assistance of some tools and a machine learning model, smart wind turbine was formed that eliminates expensive sensors reduces sensor complexity. Squirrel cage induction generator (SCIG) six rotor blades make up proposed design, depending on wind's direction, itself can rotate hub to produce energy more effectively. Additionally, two stepper motors are coupled yaw mechan...

Most three-phase, squirrel-cage, induction motors (IMs) are oversized. In the European Union (EU), the average load factor of IMs is slightly lower than 60%. In fact, in some industrial sectors, a large quantity of motors operates with a load permanently significantly under that value (e.g., 25-30%). Therefore, since the load factor is an average of the motor load over its operating cycle, it c...

The induction motors effort to widely industrial fields. On the contrary, faults of the induction motors cause another faults of the whole system, because the faults of the induction motors often progress through long time. It is very important that diagnosis for diagnosis fault and extracted fault feature from the acquired signal using wavelet transform. Extracted features use the fault diagno...

Electrical motors drive a variety of loads in today’s world. Almost every industrial process relies on some kind of electrical motors and generators. There exist billions electric motors used in different applications all over the world. Majority of them are small fractional HP motors use in household appliances. However, they used about 5% of the electricity used by the motors. Three phase mot...

A new hybrid analytical model (HAM) based on conformal mapping (CM) method and magnetic equivalent circuit (MEC) is presented in this paper for electromagnetic modelling of cage rotor induction motors (CRIMs) used electric submersible pumps (ESPs). For every operating point, the iron parts are modelled with a non-linear MEC to calculate virtual currents, which represent influence magneto motive...
