Torque Ripple Minimization of BLDC Motor by Kalman Filter
In classical control of brushless dc motors, flux distribution is assumed trapezoidal and fed current is controlled rectangular to obtain a desired constant torque. However, in reality this assumption may not be correct due to nonuniformity of magnetic materials and design trade-offs. These factors together with current controller limitation, can lead to an undesirable torqueripple. Hence torqu...
متن کاملBLDC Ripple Torque Reduction via Modified Sinusoidal PWM
This paper introduces a BLDC fan motor driver system using modified sinusoidal PWM (SPWM). The driver board is assembled in the motor to minimize system size. Based on the signal from the hall position sensor on the board, the controller generates the SPWM to the power module to drive the BLDC motor. Because it's SPWM instead of square PWM, there is no pulsation torque. The simulation and exper...
متن کاملInvestigation of Slim Type BLDC Motor Drive with Torque Ripple Minimization using Abridged Space-Vector PWM Control Method
Received Feb 14, 2017 Revised Apr 14, 2017 Accepted Apr 29, 2017 Brushless DC (BLDC) motors are becoming an increasingly popular motor of choice for its unique characteristics. The BLDC motor drive is assumed to have trapezoidal back-electromotive force (EMF), rectangular phase currents and together produces the desired torque. However, practical back-EMF waveform might not be exactly trapezoid...
متن کاملTorque Ripple Reduction of Electrolytic Capacitor-less BLDC Motor Drive
Brushless DC motors called BLDC are used in many industrial and non-industrial applications today for reasons such as very high efficiency, easy control method and high reliability, and their use is increasingly used in mass production applications, especially home appliances. But these motors require the use of an electric drive, even in constant speed applications. Commercialization of these ...
