“…Electronically commutated switches for rotor position detection have been used for motor speed control [12]. Fault isolation, based on fault signature tables, has been tested under noisy motor conditions [13]. Detailed analysis using Ansys software has been employed to identify the main sources of vibration in BLDC motors, including the participation of individual parts like stators and rotors [15].…”

This research paper focuses on the vital role of Brushless Direct Current (BLDC) motors in hybrid vehicle propulsion due to their efficiency and compact design. The primary objective is to evaluate BLDC motor performance within a vehicle chassis, with a specific focus on vibration characteristics. An innovative rotational tracker program is introduced to identify rotating machinery faults efficiently, reducing computational costs and aiding machinery selection for specific applications. The research involves comparing vibration characteristics of BLDC and stepper motors, using a 4kW BLDC motor to measure displacements along the X, Y, and Z axes within specified RPM and torque ranges while monitoring current variations during chassis installation. Findings emphasize the significance of proper motor installation in hybrid vehicle design to mitigate increased vibration levels. This study has implications for motor manufacturers and vehicle designers, underlining the importance of considering vibration performance during motor installation. It concludes by suggesting further research on broader RPM range BLDC motors and on-road measurements to advance understanding in the context of hybrid vehicle propulsion. In summary, this research explores the connection between BLDC motors, vibration characteristics, and their impact on vehicle performance, with significant implications for the automotive industry.

“…A rolling bearing unit's sudden fault or damage may lead to an unexpected halt on the production process, even significant economic loss. Therefore, many diagnostic techniques have been developed to support the predictive maintenance of rolling element bearings, in which vibration-based fault diagnosis is the most used [1], [2].…”

“…In a BLDC motor, the magnetic field generated by the rotor rotates at the same frequency 20) , in addition to these advantages, electric motors are also inseparable from the dangers of overuse, such as the use of BLDC in electric vehicles when used continuously and when they have a vehicle load that exceeds the usage limit of a BLDC motor. These things will have an impact on increasing heat at the motor temperature of the BLDC so that there will be a decrease in the quality of performance on the BLDC motor, which is due to vibrations caused by vehicle shocks 21) , so that the insulation of the motor dynamo windings is damaged which can burn in its worst condition 22) .…”

Electric vehicles generally use a Brushless DC (Direct Current) motor as the main motor of the vehicle. Brushless DC Motor is not an instrument with a perfect level of efficiency. Brushless DC motors can still overheat at certain times, thus damaging the insulating material of the motor. Damaged motorcycles are obtained when the vehicle continues to operate over long distances and for long periods. In these conditions, the motor efficiency will drop significantly. This paper proposes designing a cooling system on a Brushless DC casing by applying a hollow fin that is continuously flowing with water. A Brushless DC motor casing design is simulated using software to determine the actual conditions of water circulation that occur in the design. Furthermore, this study uses an empirical and comparative approach to evaluate the efficiency of a cooling system. The results showed that the design of a hollow fin cooling system with water media tended to experience an efficiency of 43.410% and an increase in the average efficiency of the previous study of 17.348%.
