Research of a Novel Commutation Control Strategy of BLDCM
2008 International Conference on Computer Science and Information Technology, 2008Brushless DC motor (BLDCM) has the question of torque ripple and it will influence the motor's running stability. The theory of commutation torque ripple of BLDCM was analyzed firstly. After the study of the stop process of BLDCM, it was proposed that the motorpsilas stop precision will be affected when commutation occurs in the stop interval ...

Analysis of skew effects on cogging torque and BEMF for BLDCM
Conference Record of the 1991 IEEE Industry Applications Society Annual Meeting, 2002The variation of air gap permeance distribution is described considering the geometrical air gap. Using the air gap permeance distribution and the air gap MMF distribution, air gap flux density distribution is obtained. Equations representing cogging torque and back EMF (BEMF) are induced analytically.

Research on Sensorless Control System of BLDCM Based on TMS320F2812
Advanced Materials Research, 2012An electronic control system for sensorless BLDCM is proposed. Normally, the back-emf signal has coupling noise from the PWM signal which is used to vary the speed of the motor. So it is difficult to detect the zero-crossing point accurately when the motor work at low speed. In order to improve the controllability of BLDCM at low speed, a new algorithm
