“…Harmonic values increased for phase-shifted (hall sensor-shifted) in 66V. This condition arises from electronic elements (semi-conductive) being available on the driver circuit ( Alaeinovin et al, 2008;Wang et al,2011). But again, as the voltage value increases, both the rotational speed increases and the percentage of harmonic values decrease.…”

Abstract:In this paper, the hall sensor's location for the optimal operating range of a bipolar brushless direct current motor (BLDCM) have been investigated experimentally. It is quite a difficult task to determine the exact and accurate rotor position to locate the hall sensor in a way that will have the most efficient impact on the operation parameters of a motor. In addition to theoretical work, experimental studies are required to operate a motor in steady state conditions. Therefore, special attention is being paid while measuring harmonic, torque, and speed values depending on the hall sensor's position. Experimental results of BLDCM are discussed and comparative analysis is performed. The results of this study are supported by theoretical information as well.

“…Most of the studies of the BLDC motor assume that correct positioning of the hall sensors means that they are spaced at intervals of exactly 120 electrical degrees, which may not be true for many of the low-cost, low-precision motors that are mass produced on the market [4].…”

“…In order to reduce such effects, various approaches have been developed [4][5][6][7][8][9], with the methods developed in [4][5][6][7] concentrating on the effects of using different combinations of hall sensors. The use of typical approaches for estimating rotor position from filtered hall-effect sensor signals, such as averaging and extrapolation, can ensure that the hall-effect sensors are electrically spaced at 120 degree intervals; however, the absolute positions of the hall-effect sensors cannot be aligned for each phase.…”

-This paper presents an improved approach for compensating rotor position signal displacement in brushless DC (BLDC) motors with misaligned hall-effect sensors. Typically, the halleffect sensors in BLDC motors are located in each phase and positioned exactly 120 electrical degrees apart. However, limitations in mechanical tolerances make it difficult to place hall-effect sensors at the correct location. In this paper, a position error compensator to counteract the hall-effect sensor positioning error is proposed. The proposed position error compensator uses least squares error analysis to adjust the relative position error and back-EMF information to reduce the absolute offset error. The effectiveness of the proposed approach is verified through several experiments.
