The Brushless DC (BLDC) motor is a simple robust machine which has found application over a wide power and speed of ranges in different shapes and geometry. This paper briefly reviews the fundamentals behind the motor and also the different types of BLDC motors with different geometries and then presents a new configuration for BLDC motor/generator, which does not use a permanent magnet in the ...

Shaft position sensing is an essential part of switched reluctance (SR) motor drive In order to synchronize the pulses of phase current with the period of rising inductance of the proper motor phase. Direct sensors such as, Hall effect and optical encoder are commonly used in SR motors. The purpose of this paper is to present an indirect shaft positioning sensing known as "sensorless " control ...

Water pumping using AC motors has become one of the most feasible photovoltaic (PV) applications. Moreover, PV pumping is getting more attention in recent days mainly in remote areas where connection to the grid is technically not possible. Power generation by Photovoltaic is reliable. The operation and maintenance costs are low. The induction motor is more rugged, and maintenance-free motor. I...

Energy efficiency is an essential aspect of motor technologies. The replacement conventional Single Phase Induction Motor (SPIM) by Permanent Magnet Synchronous (PMSM), Reluctance (SynRM), or Switched (SRM) for energy-efficient operation leads to high capital expenses. This paper presents a cost-effective design method improve the existing SPIM. It implements novel idea transforming it Line Sta...

<span lang="EN-US">Single-phase induction (asynchronous) motors are widely used at home. These have two windings and usually operate a lower performance than 3-phase asynchronous which three windings. For this reason, study aims to design new winding of single-phase motor by increasing the number phases in order increase motor. This research was focused on 36 slot capacitor-start capacito...

This paper deals with the design and evaluation of a robust controller for static VAR compensator (SVC) in remote industrial power systems to enhance the voltage profile for three-phase single cage induction motor (SCIM) loads. The controller design is based on H∞ theory to deal with uncertainties arising in industrial network modelling. &#10The performance of the H∞ controller has been evaluat...

<span lang="EN-US">Single phase induction motor (SPIM) has zero torque, this many types and the main objective is to find starting torque of motor. This done by providing auxiliary coils that are mechanically separated or weakened after 75% engine speed. The real problem here these windings occupy a third iron core motor, when they weakened, capacity not fully used must withstand rated lo...

Switched reluctance motor (SRM) drive has remarkable characteristics that make it attractive for high-speed applications. As the motor's speed increases the shape of the current waveform changes in such way that limits the production of motoring torque. At high speeds, it is possible for the phase current never reaches the desired value due to the self e.m.f. of the motor, therefore, the torque...
