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...

Further, the electronic control that BLDC motors offer is critical to statutory vehicle requirements such as energy-saving, reduced environmental impact, and the creation of safer vehicles. BLDC motors are also useful for variable-speed applications where space is tight, such as fuel pump control and electronic power steering. In these types of applications, electronic control is essential due ...

Light urban electric vehicles are an important target, both for the researchers and manufacturers. Concerning the motor’s choice, more ways are investigated, but the most important is that as compact as possible solutions have to be used. In the top of the preferences, the permanent magnet synchronous motors (PMSM) and brushless DC motors (BLDC) are situated. These are preferred thanks to their...

In high power high voltage application BLDC motor are widely used because of high efficiency, simple construction, low cost less maintenance and high torque or high output power per unit volume. For driving the BLDC motor we required inverter. PWM inverter which gives good performance. In two level inverter there is a problem of harmonics distortion, lower electromagnetic interference, high DC ...

This paper presents the method of reducing torque ripple of brushless DC (BLDC) motor. The commutation torque ripple is reduced by control of the DC link voltage during the commutation time. The magnitude of voltage and commutation time is estimated by a neural network and optimized with an optimization method named particle swarm optimization (PSO) algorithm analysis. The goal of optimization ...
