“…Literatures have proven that rare-earth PMs improve power density and dynamic performance [4]. The problem with PMs, other than the availability concerns, is that there is a change of demagnetization in very high-temperature environment [5]. Moreover, the structure is less rugged, if compared to non-PM motors.…”

Switched reluctance motors (SRMs) are simple in structure, easy to manufacture, magnet-less, brushless, and highly robust compared to other AC motors which makes them a good option for applications that operate in harsh environment. However, the motor has non-linear magnetic characteristics, and it comes with various pole-phase combinations and circuit topologies that causes many difficulties in deciding on which type to choose. In this paper, the viability of SRM as a low-cost, rugged machine for vehicle radiator cooling fan is considered. First, necessary design considerations are presented, then three commonly use types of SRM are analyzed: A 3-phase 6/4, 3-phase 12/8, and a 4-phase 8/6 to find their static and dynamic characteristics so the most suitable type can be selected. Simulation results show that the 8/6 SRM produces the highest efficiency with less phase current which reduces the converter burden. However, with asymmetric half bridge converter, eight power switches are required for 8/6 SRM and thus put a burden on the overall drive cost. As a solution, the Miller converter with only six switches for four phase SRM. To verify the proposed idea, the 8/6 SRM was manufactured and tested. The results show that Miller converter can be used for the proposed SRM with slightly reduced efficiency at 80.4%.

“…This is mainly due to presence of permanent magnets in the rotor where Joule losses are much lower than those in induction motors with squirrel cage or rotor windings. The main issue related to the adoption of PMSMs is the demagnetization effect in permanent magnets and the consecutive reduction of efficiency [1], [2]. From a physical point of view, demagnetization in permanent magnets is a very complex process which depends on many factors such as: external magnetic field, temperature, microstructure of the permanent magnet, etc [3], [4].…”

The impact of granular microstructure in permanet magnets on eddy current losses is investigated. A numerical homogenization procedure for electrical conductivity is defined. Then, an approximated simple analytical model for the homogenized conductivity able to capture the main features of the geometrical and material dependences is derived. Finally eddy current losses analytical calculations are given, and the two asymptotic expressions for losses in the stationary conduction limit and advanced skin effect limit are derived and discussed.

“…In recent years, a wide variety of synchronous machines are produced. These machines can be used in industry as motor and compensator, energy generation as generator (Hansen & Michalke 2008;Adlya & Huzayyin 2019;Bayındır & Vadi 2017). Particularly because of their high efficiency, there is increasing interest in synchronous machines (Bouloukza et al 2018).…”

In recent years, the variable speed motor drive is supported over a fixed speed motor drive as per essentialness safeguarding, speed or position control and improvement of transient response characteristics. The aim of any speed controller is to take main signal that represent the reference speed and to drive the framework at that reference speed. This paper exhibits the design, simulation and control of synchronous reluctance motor (SynRM). In addition, the motor speed is controlled by utilizing a conventional PID controller that has been used from the cascaded structure. The Particle Swarm Optimization (PSO) was used to find the best parameters of the PID controller. Lead-Lag controller presents from the cascaded controller as the following period of control. The Space vector pulse width modulation (SVPWM) plot has been proposed to control the motor and make the motor work with no rotor confine contingent upon the info parameters that utilization in the simulation. An examination between both of PID tuned and PSO tuned controller affirms that the PSO gives dazzling control highlights to the motor speed and have an edge over the physically changing controller. Thus, this paper present investigation and simulation for the most precise procedures to control the speed reaction and torque reaction of synchronous reluctance motor (SynRM).©2020. CBIORE-IJRED.
