Abstract
This study addresses faulty hall sensors in Brushless DC (BLDC) motors, presenting a novel, cost-effective solution using low-budget microcontrollers. The research employs signal processing techniques and high-speed microcontrollers to emulate hall sensor signals, eliminating the need for expensive Field Programmable Gate Arrays. Experimental results demonstrate successful hall sensor emulation and effective BLDC motor operation under faulty conditions. The proposed method significantly improves motor reliability and reduces downtime, particularly relevant to Nigeria’s rehabilitation robotics, manufacturing, and electric mobility sectors. By providing a locally implementable solution, this research contributes to Nigeria’s technological advancement and industrial efficiency. The study’s findings pave the way for enhanced BLDC motor resilience, offering a promising approach to maintaining motor functionality in resource-constrained environments.
Keywords: BLDC motors, Hall sensors, Microcontrollers, Nigerian industry, Signal emulation.

1. If Nigeria manufacturing plants relies on BLDC motors for conveyor belt systems. Due to frequent power fluctuations and overheating, Hall sensors in these motors fail intermittently, causing erratic motor behavior. How does Hall sensor failure affect the six-step commutation process of a BLDC motor in real-time operation?
2. What hardware-in-the-loop (HIL) testing methods can be used to validate the accuracy of an emulated Hall sensor signal?
3. What fault-tolerant control algorithms can detect and compensate for transient Hall sensor failures?
4. What impact do power fluctuations have on the timing accuracy of emulated Hall sensor signals?
Thanks for engaging, Torsaa.
1. The essence of commutation in a motor is to allow the flow of current in a particular section of a winding in phases and this affords us a rotational motion. Carbon brushes are the old guys that assist in transmitting this current to the appropriate windings of our stator. Now, hall sensors are frictionless and do not wear out, hence their preferred use in high-end and detesting devices, the hall sensors give positional feedback to the motor driver which based on the insight given ignites the appropriate windings. An absence of this positional feedback translates to the inability of the motor driver to know which winding to ignite with current.
2. Every BLDC motor has a datasheet, you don’t need an HIL to test the functionality of the hall sensors in a motor, by studying the datasheet, you’d see the hall sensor wires, following the step in the paper, you only need to connect them to the output of an oscilloscope. Once they’re connected, compare your result with what is seen on the datasheet.
3. Adaptive feedback control will be the best, that is, one has to anticipate a fault enough to provide a backup or standby solution that switches immediately after an out-of-phase sequence is detected in any of the hall sensors.
4. Now, the motor is wired to the motor driver, meaning that the motor gets its power from the motor driver, hence, I’d love to rephrase the question to target the motor driver. Once the motor driver does not receive enough power, it’d in-turn be unable to distribute power to the BLDC motor as required. This can lead to jerking of the motor, phase lock of the motor and a “danger-alarm” by the motor driver which would halt all motor operations.
Super-brilliant as always
