Detailed discussion of the test results, empirical relations between the main operating parameters of axial flux BDCM (torque, speed, airgap) and the resulting output (power output, maximum torque, power loss, maximum speed, efficiency) are described in this paper. A scalable model for the motor performance using variable airgap was developed and included in the ADVISOR model to simulate hybrid-electric sedan meeting PNGV goals.]]> Thu, 23 Feb 2023 09:31:13 GMT https://trid.trb.org/View/1791458 Adaptive speed controllers based on artificial intelligent techniques for unmanned vehicle electric propulsion system https://trid.trb.org/View/2087513 Wed, 22 Feb 2023 09:41:10 GMT https://trid.trb.org/View/2087513 A study on improving the efficiency of non-isolated buck-boost bidirectional DC–DC converter https://trid.trb.org/View/2085771 Tue, 24 Jan 2023 09:31:40 GMT https://trid.trb.org/View/2085771 Robust PID Controller With Computational Intelligent-Based Decision Maker for Brushless DC (BLDC) Motor in Electric Vehicle for Indian Roads https://trid.trb.org/View/1820111 Thu, 14 Jul 2022 11:32:56 GMT https://trid.trb.org/View/1820111 Selection of a Brushless DC Motor Employed to Propel an Electric Car https://trid.trb.org/View/1824374 Fri, 17 Jun 2022 09:20:13 GMT https://trid.trb.org/View/1824374 Design and Control of a Light-Weight Drive-Integrated 48 V BLDC Motor for Radiator Fan in Hybrid Vehicle https://trid.trb.org/View/1832493 100-volt-systems used for vehicles in other segments. These systems also have advantage of reduced copper weight due to reduced current. As 12 V systems are replaced by the 48 V systems, the auxiliary 12 V loads would necessitate implementation of a DC-DC converter. Considering the requirements of auxiliary loads that are fed from 12 V battery, the power rating of the DC-DC converter can get considerably high resulting in increased size. Hence, it is advisable to re-design at least some of the 12 V auxiliary systems to 48 V such as the radiator fan motor. This, along with the issues faced in the existing PMDC Motor with regard to efficiency and sizing have generated interest to investigate better alternatives for the motor. To this end, this paper describes the design, development and control of a Brushless DC Motor to be used as a radiator fan. The improved design results in weight reduction and increase in percentage efficiency by about 30 compared to the conventional DC Motor. In addition, issues like sparking and maintenance of brushes for a 48 V DC motor are also eliminated. A low-cost integrated PCB controller is developed to implement the control strategy using Microchip PIC 2231 micro-controller. Finally, the drive is implemented and tested with the radiator fan and the results are presented.]]> Mon, 02 May 2022 09:30:29 GMT https://trid.trb.org/View/1832493 Novel Operating Mode for DC-to-DC Converters in PHEVs https://trid.trb.org/View/1828684 Mon, 25 Apr 2022 17:01:17 GMT https://trid.trb.org/View/1828684 Test Results of A Sensor-Less, Highly Nonlinear Electro-Mechanical Brake https://trid.trb.org/View/1831080 Fri, 15 Apr 2022 09:06:52 GMT https://trid.trb.org/View/1831080 Deep learning based automatic vertical height adjustment of incorrectly fastened seat belts for driver and passenger safety in fleet vehicles https://trid.trb.org/View/1905139 Tue, 25 Jan 2022 09:50:46 GMT https://trid.trb.org/View/1905139 Overview on BLAC and BLDC motors: designs and mathematical modelling https://trid.trb.org/View/1877532 Thu, 16 Dec 2021 16:08:37 GMT https://trid.trb.org/View/1877532 Requirements and Transition of Onboard Reactors https://trid.trb.org/View/1874800 Tue, 14 Dec 2021 17:50:42 GMT https://trid.trb.org/View/1874800 Iron-Loss Modeling With Sensorless Predictive Control of PMBLDC Motor Drive for Electric Vehicle Application https://trid.trb.org/View/1874888 Tue, 26 Oct 2021 14:25:40 GMT https://trid.trb.org/View/1874888
