This paper presents the overall review of torque ripple reduction techniques in brushless DC motors (BLDC) and different multilevel inverter topologies suitable for BLDC motor drives. BLDC motors are widely used for household applications due to its features of high reliability, simple frame, high efficiency, fast dynamic response, compact size and low maintenance, etc.. The switches are electr...

The low-RPM Torque Converter (LRTC) is a rotating generator concept for use on the seabed with driving force from sea waves motion surface. This built up of two identical generators connected opposite each other via spring drum built-in ball bearing clutch. to buoy surface wire, wire rolled around drum. With waves, moves either upwards or downwards and pulls downwards. movement causes spin.&#x0...

The torque ripple of a switched reluctance motor (SRM) limits its application in electric vehicles. This paper proposes DITC system for SRMs based on novel multilevel converter (MLC), which aims at the problem that cannot be effectively suppressed conventional direct instantaneous control (DITC) an SRM due to limitation DC bus voltage asymmetric half-bridge (AHBC) and single strategy formulated...

Abstract Cavitation inside a torque converter induces noise, vibration and even failure, these effects have been disregarded in previous design processes. However, modern applications require attention to this issue because of its high-speed high-capacity requirements. Therefore, study investigated the cavitation effect on using both numerical experimental methods with an emphasis influence cha...
