This paper deals with the optimal design of a new synchronous motor particularly suitable for electric vehicles. The unique advantage of this motor is its possibility to realize field weakening at high speeds, which is the most important demand for such drives. The main design goal is to identify the dimensions of certain crucial regions of the machine in(More)
The paper presents an unconventional approach to control Electric Controlled Permanent Magnet Synchronous Machine (ECPMSM) with universal method to determine its required parameters. Moreover, two different kinds of supply the additional control coil of the prototype machine have been analyzed in details. In the first variant, the control coil is placed(More)
Proposed paper presents a fast algorithm for determining static and switching losses of power electronic devices in three-phase DC/AC inverters for different semiconductor materials. This method uses table - form, stored characteristics of individual semiconductor devices, without a necessity of detailed, time resolved analysis of the commutation process.(More)
The paper introduces an “a-priori” look-up-table procedure for an efficiency-optimal inverter-machine control system. This method has been applied for a hybrid excited permanent magnet synchronous machine. An exemplary machine model is proposed and a prototype is introduced with stator-located excitation coil. An iterative process for optimal(More)
This paper discussed a control system for an HPMSM machine with a stator based field coil aiming at maximum efficiency of the inverter-machine system. A new procedure for efficiency-optimal inverter-machine propulsion system has been introduced. An iterative process for optimal current distribution is described with multidimensional tables of overall losses(More)
The paper presents the optimization and comparison of different rotor design concepts of an Electrically Controlled Permanent Magnet Excited Synchronous Machine (ECPMSM) possessing a field control capability. The experimental results of a no-load back electromotive force (back-EMF) waveforms, cogging torque and electromagnetic torque values are presented in(More)
