Abstract

For dynamic applications like automotive, pumping, and rolling, brushless direct current (BLDC) motors are generally preferred. The use of BLDC motors is predicted to become mainstream in industries by 2030, replacing traditional induction motors. Industrial and commercial applications of BLDC motors are growing, however, the future of the technology remains in doubt. BLDC motors do not meet the requirements for improved fault tolerance, current ripple, or torque ripple when considering reliability and durability. The novel BLDC motor has been designed and analysed in magnet software. In the current wave shape, commutation between phases that results in a rotating magnetic field synchronised to the phases is the main cause of ripples. These waves in the commutation process result in mechanical pulsation and noise. An innovative method for lowering the commutation torque ripple is presented in this article. This research presents an efficient pulse amplitude modulation (PAM) of DC-link voltage based reduction in torque ripple for the novel designed BLDC motor drivers. Additionally, a hybrid Cuk voltage-gain converter with a high gain and decreasing supply voltage ratings is utilized at the front end. The inverter’s DC link is connected to an auxiliary switch for controlling phase current at the input during the change overs in phase of the inverters. Using a novel BLDC motor prototype, the proposed design is theoretically verified by the MATLAB simulation. The suggested BLDC drive can results in minimising the motor's torque ripple by roughly 70%.
