“…The current density, current and voltage values for both operations will be the same with the PMSM so as not to exceed the kVA rating of the existing driver. The optimum number of poles for a PMaSynRM is 4 or 6 poles and it is evident from the literature [18,19]. Pole number is chosen as 4 for the application.…”

This study presents a comprehensive design procedure of a permanent magnet assisted synchronous reluctance machine (PMaSynRM) for replacing a permanent magnet synchronous motor (PMSM) in a commercial washer. The motors used in these applications have to perform efficiently on a wide speed range with constant-torque region for washing, and fieldweakening region for spinning. A design methodology is determined consisting of electromagnetic design, thermal/mechanical stress analysis, optimisation and prototyping. There are limitations and decisions on the initial design steps, considering the volume allocated for the machine, magnetic material and permanent magnet (PM) selection and the electromagnetic parameters for constant-torque and field-weakening regions. Design process is carried out following the initial parameter selection then the motor is produced and tested. Test results show that the PMaSynRM is 8.26% higher in volume and lower in power density than those of PMSM with a better field-weakening characteristic and fault tolerance. As a result, the authors proposed a methodology to design a PMaSynRM which becomes a good alternative for the mass produced home appliance motors since the materials' amount are decreased in 20% for silicon steel and 50% for PMs consequently decreasing the total cost and offering nearly the same efficiency and power density for the application.

This paper proposes a simple method to calculate a current-vector trajectory for enhanced operation of electric power generation system based on a synchronous reluctance machine (SynRM). Due to magnetic saturation and cross magnetization, the performance and torque capability of a SynRM vary according to the position and value of the stator current. State of the art control methods usually assume parameters with constant values, especially the inductance, neglecting saturation, leading to possible uncertainty in the machine operation. Therefore, a current-vector trajectory to operate this type of machine, as a generator, in an extended speed range, with enhanced performance and considering magnetic saturation is proposed. A straightforward algorithm based on the inductance characteristic of the machine is used to calculate the trajectory of the stator current vector. This trajectory is evaluated via numerical simulation of an experimentally validated finite element model of a SynRM. The results show that the proposed current-vector trajectory can improve the torque capability to 5 % concerning the estimated trajectory without considering saturation. Experimental results are also provided to demonstrate the enhanced operation of the generator.
