Research of sensorless controller of BLDC motor
IEEE 10th International Conference on Industrial Informatics, 2012Sensorless control technology has been a hotspot in the area of BLDCM control. In this paper, a speed controller of BLDCM based on MC56F8013 was researched using BEMF-crossing-zero-detecting method, including hardware circuit and software design. Experiments were implemented and it shows that the BEMF method for detecting rotor position signal is ...

Comparative Study of BLDC Motor Modeling
2018 Australian & New Zealand Control Conference (ANZCC), 2018Transfer function is a widely employed kind of mathematical model. First order and second order transfer function with voltage input and motor speed output are broadly used as models of BLDC motor. Since there exists uncertainty and nonlinear phenomena in the real time world, simulation and practical experiment have been done to compare uncertainty ...

Position control of BLDC motors
Advances in Optical and Mechanical Technologies for Telescopes and Instrumentation III, 2018Fiber spectroscopic telescopes are important tools for astronomy research. In spectroscopic telescopes, the positioning of thousands of fibers on the focal plane is a big issue, which is usually solved by some compact structured devices with small-size motors installed. Stepper motors are normal choice for fiber positioner, however, stepper motors’ low

Robust torque optimization for BLDC spindle motors
IEEE Transactions on Industrial Electronics, 2001A robust design for torque optimization of brushless DC spindle motors applied in a hard disk drive, using the Taguchi method, is described and illustrated in this paper. The optimal design process takes into consideration noises that arise in the manufacturing process, such as manufacturing tolerances for the stator tooth shape and variation of the ...

Identifying dynamic model parameters of a BLDC motor
Simulation Modelling Practice and Theory, 2008Abstract An off-line identification method founded on the least-squares approximation technique and a closed-loop disturbance observer is applied for identifying the parameters of a BLDC motor model. No special configuration of the motor is required besides the availability of experimental data for back-EMF, phase currents, rotor position, and rotor ...

Retroactive Control Applied to a BLDC Motor
2021TheBLDCmotors are attractive to applications for automobiles, aviation, and robotics, and, as a consequence, the motor is exposed to charge disturbances and variations, which make that control techniques usually applied, such as the derivative integral proportional controller (PID), not reach its variables accurately and quickly.

Noise source identification of a BLDC motor
Journal of Mechanical Science and Technology, 2008This paper proposes an analysis procedure of brushless DC(BLDC) motor noise. A systematic approach for identification of noise sources is suggested considering electromagnetic forces, structural and acoustic modes. It is proved by finite element analysis and experiments that the electromagnetic forces and the structural modes are not the major noise ...
