“…Due to their reliability and efficiency, brushless DC (BLDC) motors are known to be excellent choices to be applied in different application fields, including aerospace systems, chemical industry, and electric vehicles, to mention just a few [1][2][3]. The motor functioning in an unhealthy mode will undoubtedly lead to principal problems and issues, decreasing the efficiency, safety, or system reliability.…”

This research aims to investigate a fault detection method applicable to the stator part of the Brush-Less DC motor (BLDC). Indeed, it is a concern to make sure the motor is operating in a healthy mode, and in any other case, it is of great importance to detect the fault as soon as possible to prevent the further ruin of the major system. Regarding this, a sub-branch method of the Wavelet Transform analysis, named Continuous Wavelet Transform (CWT), is utilized to observe the short-circuit fault in the stator coils. Thus, a novel simulator of the BLDC motor is developed by making an interconnection between ADAMS and MATLAB in which different electrical and mechanical components are included. Therefore, a close-to-reality model of the BLDC motor is achieved, leading to a more accurate evaluation of the proposed method. An energy-type feature will be suggested to characterize the fault happening. Through acquiring the normalized energy amount for one of the wavelet coefficient signals, obtained by the CWT, and comparing the energy with a predefined threshold amount of energy for that signal, it is feasible to detect the stator's flawed performance. By conducting different simulations, the proposed method will be validated.

“…Many researchers use the standard BLDC motor model as a mathematical dynamic equation [3,22,23]. Although this model tries to consider as many aspects of the actual motor as possible, some elements are still not included in this model, such as the rotor's static and dynamic imbalances.…”

O presente trabalho apresenta o estudo e comparação de dois algoritmos para a redução do ripple de torque de máquinas BLDC. Devido às suas características, como a forma de onda da força contra-eletromotriz, e dificuldade em sintetizar correntes retangulares, pode-se resultar na presença de ripple de torque quando a máquina BLDC é acionada. Para reduzir este ripple de torque, vários estudos são encontrados na literatura. Nesse sentido, o presente artigo apresenta a comparação de dois métodos para redução do ripple de torque de máquinas BLDC. Resultados de simulação são apresentados para demonstrar as vantagens de cada técnica.

“…The power circuit configuration reported in the literature [15][16][17][18] presents a fault-tolerant strategy for OCFs in switches and the motor phase windings. This article recommends the employment of multi-phase open-end winding PM-BLDC motor (OEWBLDCM) drives for such applications, where the reliable operation of the drive is the primary concern.…”

SummaryThis paper proposes a fault‐tolerant power converter for a voltage source inverter (VSI)‐driven permanent magnet brush‐less direct current (PM‐BLDC) motor drive, which is suitable for low‐power electric vehicle (EV) applications. With the proposed topology, it is possible to deliver rated power to the PM‐BLDC motor even after the incidence of either an open‐circuit fault (OCF) or a short‐circuit fault (SCF) in any one of the switches, which constitute the VSI. The proposed fault‐tolerant PM‐BLDC motor drive requires fewer additional sensors and components compared to the fault‐tolerant power converters, which are reported in the previous literature. Cost analysis, carried out for a 3‐kW motor drive, reveals that an additional cost of only 5% is added to the raw material cost of the traditional PM‐BLDC motor configuration to facilitate fault tolerance. The fault‐tolerant operation of the proposed power converter is experimentally verified with a low‐power laboratory prototype.
