Features of segment winded PMSM for a low voltage supply system

Istvan Szenasy Zoltan Varga

Publication Name: 2017 3rd International Conference on Control Automation and Robotics Iccar 2017

Publication Date: 2017-06-07

Volume: Unknown

Issue: Unknown

Page Range: 523-528

Description:

This paper presents a symmetric winded PMSM which is connected by all in part coil to a supply system at low voltage of 48-100 V DC, developed by Research Center of Vehicle Industry in Szechenyi University. It has several benefits of this winding system its separate supply. The motor construction is slightly different from the general constructions; its running and control are different but on the whole offers new availabilities and prosperous solutions as well as electrical motor features. The paper presents some results of investigations mainly in the control for this divided kind of PMSM which was patented in 2014.

Optimum control strategy for PMSM in field-weakening region by constant power

Description:

For electric vehicles an applied control of PMSM is the flux weakening operation for extending the region over nominal speed on nominal voltage. This paper deals with these questions and its impacts. Proved methods increase the torque angle and the d axis directed component of the stator current vector reduces the main flux, but the eddy current loss developing in magnets became significant. These impacts and their reduction need several investigations. This paper preents the possibilities and limits of flux-weakening for a given PMSM, and gives a usable optimum control strategy on nominal power's region by varied speeds.

The proved method increases the torque angle and with this the d axis directed component of the stator current vector for reduce the main flux, but the loss developing in magnets became significant.
