Dual Stage Speed Control of BLDC Motor Using Hybrid QPSO-CSO Technique

Systems for driving motors are frequently employed with renewable energy sources. By using cutting-edge methods and algorithms, the power converter controlling technology boosts performance. The switching state of the converter from the solar module’s generation unit is where the QPSO (Quantum Particle Swarm Optimization) technique is applied in the currently available work. The duty cycle depends on the swarm velocities, which indirectly depends on the QPSO parameters. Hence, the QPSO parameters inertia (W), and learning coefficients C1 and C2, were determined using the Cuckoo search algorithm (CSO). This approach helps to extract the most powerful solar panel output and continuously operate a BLDC motor performance increasing the power converter controlling technology by utilizing state-of-the-art techniques and algorithms. Every module of the suggested boost converter was examined by the experimental findings. Based on generation and load, a boost converter module is obtained. The Models for single-ended primary inductors (SEPIC) and zeta converters are contrasted with the suggested logic. The overall design model is done by using MATLAB/Simulink 2021a.

Implementation of BL-PFC Converter Fed BLDC Motor Drive for Application less than 800 W

This article analyses the performance of a PFC SEPIC-fed BLDC motor drive for low-power applications. The BLDC motor’s speed is regulated by changing the DC connection voltage of the VSI that supplies the BLDC motor. The VSI feeding BLDC motor is used to electronically commutate the BLDC motor, which works at a low frequency to minimise switching losses. A bridgeless design of a single-ended primary-inductor converter is proposed that eliminates the need for a diode bridge rectifier. A PFC-based SEPIC is intended to operate in a discontinuous inductor current mode, with a single voltage sensor, to achieve inherent power factor correction at the AC mains. The converter proposed here has a low conduction loss, a low harmonic content, and a power factor that approaches unity. Simulate the circuit by connecting the output voltage to a resistive load. The recommended drive’s output is tested experimentally on a built prototype. At the AC mains, improved power quality is achieved under all conditions, and thus the obtained power quality indices are obtained. MATLAB-Simulink is used for all simulation work.

Indonesia is a country that has tropical climate with average temperature vary in between 27°C until 37°C. BLDC motor industry is not common in Indonesia so that has to be imported from another country mostly subtropical countries. BLDC motor is built according to subtropical characteristics. Therefore, BLDC motor performance is changing in Indonesia due to the temperature differences.

Increasing power and torque capability of brushless direct current motor by employing 150-degree conduction mode controlled three-phase voltage source inverter.

With the reduction of magnet costs and the production of high-energy magnets in small sizes, permanent magnet brushless motors are used widely in various applications from household to medical, industrial, and automation applications. Furthermore, permanent magnet brushless motors have some significant advantages over the other conventional motors such as induction and brushed motors. Due to the popularity of brushless motors, they have become the focus of interest of researchers. From the past 30 years to today, the researchers have carried out numerous studies in relation to brushless motors. These studies are generally sensorless control, adaptive control, different Proportional Integral and Derivate (PID) applications, fuzzy control, PI-fuzzy and PID-fuzzy control and different Pulse Width Modulation applications and to eliminate torque ripple and other control algorithms. Permanent magnet brushless motors can be divided into two main groups. One is the permanent magnet synchronous motor and the other one is the permanent magnet brushless direct current motor (BLDCM). BLDC motors are the most preferred in applications due to their low cost and relatively simple drivers. BLDC motors are run with the classical 120-degree conduction mode voltage source inverter (VSI). Because BLDC motors run with 120-degree conduction mode inverters, power and torque produced by BLDC motors are less than their capacity, whereas BLDC motors can provide a better dynamic response, higher power, and torque by employing 150-degree conduction mode controlled VSI. In this experimental study, it is aimed to design and manufacture a versatile VSI which can control the BLDC motor in both 120 and 150-degree conduction modes. Then, BLDC motor is run in two conduction modes employing the purposed inverter under various loads, and the torque, power, and speed performance of the motor were analyzed to demonstrate the effect of the two commutation methods on BLDC motor performance. The results of this comparative experimental study have shown that the 150-degree conduction mode-controlled inverter provides with the BLDC motor generating higher power, torque, and speed than the inverter with 120-degree conduction mode.

A Permanent Magnet BLDC motor is designed for reduction in cogging torque and flux per pole. The cogging torque causes direct impact in permanent magnet BLDC motor performance by causing torque ripple problems. This paper proposes a new method for reducing cogging torque by adapting to U-clamped magnetic poles. Finite Element Analysis (FEA) is used to calculate the cogging torque and the flux per pole for different shapes of magnetic pole. It can be shown that the cogging torque could be greatly reduced by adapting to U-clamped magnetic poles. At the same time it is found that the flux per pole is also considerably reduced. The effectiveness of the proposed method is verified by comparing the cogging torque and flux per pole for various designs available in the literature.
