Side-effects of Hall sensors misplacement on BLDC motor drive operation
In this paper, the impact of Hall sensors misalignment on BLDC motor operational characteristics, i.e. DC bus current, electromagnetic torque and system efficiency, is investigated. A method for identifying and evaluating Hall sensors misplacement is described. The BLDC motor drive system is simulated in Matlab/Simulink environment software with ideally and misplaced positioned Hall sensors. Typical scenarios regarding Hall sensors angular misplacement have been simulated for the most commonly mounting configurations. The electromagnetic torque spectrum as an indicator for mechanical vibrations and noise generation has been examined. Simulations results indicate that system efficiency is decisively decreased as angular misplacement becomes greater than 30o electrical degrees.
