In this paper the design aspects of an in-wheel electrical machine to be used for traction in electric buses are discussed. The main challenges with the application are the high torque density and cost-minimisation requirements. This paper looks at all the different design aspects of the traction motor required including the electromagnetic design optimisation and thermal management.
In this paper, the design and construction aspects of a wheel actuator to be used for aircraft taxiing on the ground and which will be located in the main landing gear are addressed. The main challenges with the application are the high torque density and fault tolerance requirements. This paper will look at all the different design aspects of the traction motor required for the actuator, including...
This paper presents a Space-Vector Modulated (SVM) Direct-Torque-Control (DTC) scheme for a direct-drive permanent magnet synchronous generator (PMSG) and a gird converter for wind energy without any position sensor. Direct control of the rotating velocity and amplitude of the stator flux vector allows very fast torque response of the PMSG according to the generator speed. Fixed switching frequency...
The paper presents a direct-torque-control scheme for a direct drive variable-speed permanent magnet synchronous generator (PMSG) for wind energy without any position sensor. Direct control of the rotating velocity and amplitude of the stator flux vector allows very fast torque response of PMSG according to the generator speed. Fixed switching frequency and very low torque ripple are obtained with...
