Design and Drive-Cycle Based Analysis of Direct-Driven Permanent Magnet Synchronous Machine for a Small Urban Use Electric Vehicle
(2014)
A direct-driven permanent magnet synchronous machine for a small urban use electric vehicle is
presented. The measured performance of the machine at the test bench as well as the performance over
the modified New European ...
Influence of Travelling Current Linkage Harmonics on Inductance Variation, Torque Ripple and Sensorless Capability of Tooth-Coil Permanent-Magnet Synchronous Machines
(Institute of Electrical and Electronics Engineers (IEEE), 2014)
This paper introduces an important source of torque ripple in PMSMs with tooth-coil windings (TC-PMSMs). It is theoretically proven that saturation and cross-saturation phenomena caused by the non-synchronous harmonics of ...
Inductance Calculation of Tooth-Coil Permanent-Magnet Synchronous Machines
(IEEE, 2014)
Analytical calculation methods for all the major components
of the synchronous inductance of tooth-coil permanentmagnet
synchronous machines are reevaluated in this paper.
The inductance estimation is different in the ...
Direct-Driven Interior Magnet Permanent Magnet Synchronous Motors for a Full Electric Sports Car
(2014)
The design process of direct-driven permanent
magnet synchronous machines (PMSMs) for a full electric 4 ´ 4
sports car is presented. The rotor structure of the machine
consists of two permanent magnet layers embedded inside ...
Design of a Traction Motor With Tooth-Coil Windings and Embedded Magnets
(IEEE, 2014)
Traction motor design significantly differs from industrial
machine design. The starting point is the load cycle
instead of the steady-state rated operation point. The speed of
the motor varies from zero to very high speeds. ...
Permanent magnet synchronous generator design solution for large directdrive wind turbines: Thermal behavior of the LC DD-PMSG
(2014)
Wind is one of the most compelling forms of indirect solar energy. Available now, the conversion of wind power into electricity is and will continue to be an important element of energy self-sufficiency planning. This paper ...
Evaluation of the Efficiency of Line-Start Permanent-Magnet Machines as a Function of the Operating Temperature
(IEEE, 2014)
The standard squirrel-cage induction machine has nearly reached its maximum efficiency. In order to further increase the energy efficiency of electrical machines, the use of permanent magnets in combination with the robust ...
Heat-transfer improvements in an axial-flux permanent-magnet synchronous machine
(Pergamon Press, 2014)
Axial-flux machines tend to have cooling difficulties since it is difficult to arrange continuous heat path between the stator stack and the frame. One important reason for this is that no shrink fitting of the stator is ...
