This paper proposes a new family of electric motors based on the concept of an airgap-less device with an internal rotor. The internal flux and therefore electromagnetic torque is maximized because the rotor is allowed to touch the stator. The proposed family of motors are competitive in applications where hydraulic motors are prevalent, i.e., low-speed and high-torque requirements. Furthermore, the...
This paper proposes a new category of electric motors able to generate high torque with reduced volume, i.e., high torque density. Such a new design is denominated as an airgapless electrical motor since the rotor touches the stator as it spins. Due to its zero airgap, the proposed motor will maximize the generated torque, allowing such type of motors to be competitive in applications where hydraulic...
This paper proposes a new single-input three-output DC-DC buck converter. The proposed topology has two less switching devices than that of a conventional converter. This reduction in switching devices results in lower cost and a more even distribution of power losses among the switching devices. A comprehensive small signal Modeling and control strategies for the proposed converter will be presented...
This study presents single-input double-output unidirectional and bidirectional dc-dc buck converters, for applications that demand two dc-controlled output voltages. The proposed converters present a component count reduction and it is considered as a monolithic device with two output voltages generated by the same power converter. The main advantages of the proposed converters are reduction of costs...
