“…The performance superiority of the PMSM over the traditional induction and wound rotor synchronous motors have also been reported in [8][9][10][11]. The PMSM has also been favoured, when compared to induction motor, for line start operation, variable speed operation and in the field of semi-hermetic drives as respectively reported in [12][13][14].…”

A comprehensive comparison of the dynamic and steady state performance characteristics of permanent magnet synchronous motors (PMSM) with interior and surface rotor magnets for line-start operation is presented. The dynamic model equations of the PMSM, with damper windings, are utilized for dynamic studies. Two typical loading scenarios are examined: step and ramp loading. The interior permanent magnet synchronous motor (IPMSM) showed superior asynchronous performance under no load, attaining faster synchronism compared to the surface permanent magnet synchronous motor (SPMSM). With step load of 10 Nm at 2 s the combined effect of the excitation and the reluctance torque forced the IPMSM to pull into synchronism faster than the SPMSM which lacks saliency. The ability of the motors to withstand gradual load increase, in the synchronous mode, was examined using ramp loading starting from zero at 2 s. SPMSM lost synchronism at 12 s under 11 Nm load while the IPMSM sustained synchronism until 41 seconds under 40 Nm load. This clearly suggests that the IPMSM has superior load-withstand capability. The superiority is further buttressed with the steady state torque analysis where airgap torque in IPMSM is enhanced by the reluctance torque within 90E to 180E torque angle.

“…Recently, several efforts have been made toward the operational comparison between the permanent magnet synchronous motor and the induction motor which, hitherto, is the workhorse of the industry. These comparisons have favoured the PMSM both for fixed speed and variable speed operations [8,9]. Line-start PMSM has also been favourably compared with induction motors in the field of semi-hermetic drives, like in compressors, where heavy loading is obtained because of good cooling [10].…”

A fast hysteresis current-controlled (HCC) permanent magnet synchronous motor (PMSM) drive based on field orientation is presented. The objectives of this research are to develop and utilize HCC algorithm for field orientation control (FOC) of a complete closed loop speed-controlled PMSM drive system, optimize the HCC algorithm to obtain fast speed response with step and ramp speed inputs to examine the effectiveness of current and torque tracking, identify the optimal control variables of the HCC on the PMSM, examine the performance with ramp and step reference speed inputs. The response of the developed model is compared with the speed response of the standard AC6 of MATLAB Simpower systems in terms of rise time, settling time and effectiveness of current and torque tracking. Compared to the standard AC6 of MATLAB Simpower systems, the developed model achieved rise time and settling time of 0.0108 seconds and 0.0143 seconds respectively while the corresponding values for AC6 model are 0.1944 seconds and 0.1984 seconds respectively. The developed model, therefore, offered superior performance over the AC6 model in terms of rise time, settling time and tracking capability.

Abstract-This paper presents two design-and-analysis cases of a linestart axial-flux permanent-magnet motor: with solid rotor and with composite rotor. For a novel structure of the motor, two concentric unilevel spaced raised rings are added to the inner and outer radii of its rotors to enable auto-start capability. The composite rotor was coated by a thin (0.05 mm) layer of copper. The basic equations for the solid rotor ring were extracted. The motor's lack of symmetry necessitated 3D time-stepping finite element analysis, conducted via Vector Field Opera 14.0, which evaluated the design parameters and predicted the motor's transient performance. Results of the FEA show the composite rotor significantly improving both starting torque and synchronization capability over solid rotor.
