Abstract

In the future, hoverboards are becoming a widely used means of transportation because they are compact and more practical. The hoverboard is driven by an electric motor with a fairly low power. This paper focuses on the optimization of the hoverboard BLDC motor design. The focus of the design is done by changing the stator slot depth, stator tooth width, number of strands in hand, and number of turns by keeping the fill factor below 40%. Design optimization is carried out to obtain an increase in torque performance and efficiency which has an impact on the output power of the BLDC motor and the thermal increase that occurs. The research shows torque and efficiency improvisation on the redesign of the BLDC hoverboard motor with a power of 350W. The results of the study are comparisons of torque and efficiency from comparisons of electric motor designs. The resulting temperature is analyzed to see the effect of torque, power, and efficiency.

Abstract

The growing demand for autonomous agricultural robots requires compact, energy-efficient 12 V drives. This work designs a 12 V Interior Permanent Magnet Synchronous Motor (IPM PMSM) for field robots with targets of torque >0.8 Nm, speed >1000 rpm, and outer diameter <100 mm. Two rotor options—baselines 0° and 12° skew—were optimized and evaluated via finite-element analysis of torque, back-EMF, efficiency, and thermal behaviour. Compared with 0°, the 12° skew cut torque-ripple RMS from 0.2885 to 0.1390 Nm (−51.8%) and reduced cogging torque by >50%, while peak torque decreased only slightly (1.85 → 1.81 Nm; −2.4%). Efficiency remained high (~89%), power factor improved (0.95 → 0.964), and passive cooling kept temperatures ≤65 °C at 60 minutes. These results indicate that a 12° skew provides a practical design trade-off for low-voltage agricultural PMSMs, delivering smoother, more stable torque for precision tasks such as seeding and spraying without sacrificing overall efficiency.

Abstract

This study aims to design and implement an electronic control system to automate the GMAW welding process, focusing on precise regulation of travel speed and travel length to improve repeatability, safety, and weld consistency. The methodology is organized into four stages: (1) needs analysis to define functional requirements, user constraints, and operating ranges; (2) system design covering hardware architecture, sensor and actuator selection, and embedded control logic; (3) implementation through microcontroller-based integration of a motion drive, user interface, and parameter-setting features; and (4) testing to verify accuracy, stability, and performance under realistic operating conditions. The results demonstrate that the system regulates welding speed with an accuracy of 92.54%–99.44%, while maintaining a maximum time standard deviation of 0.038 seconds, indicating stable motion over repeated trials. For welding length control, the system achieves an average absolute error of 0.35–0.5 mm, a percentage error of 0.17%–0.7%, and a standard deviation of 0.051 mm or less, supporting consistent endpoint positioning. In real-world welding tests, the actual weld length deviation ranges from 0.20 to 1.71 mm. It remains within ISO 13920 Class D tolerance limits, confirming practical applicability for general fabrication. The developed controller enables precise parameter control over a speed range of 100–800 mm/min and a length range of 50–300 mm, reducing the need for direct operator intervention and limiting human-induced variability. Overall, the system supports safer, more consistent welding operations and provides a scalable platform for integrating additional monitoring or adaptive control functions. Suitable for training, prototyping, and routine production trials. Future work will address adaptive control diagnostics.
