“…By deepening the cage slots, optimizing cage shape, using solid steel for the rotor, axial slots, and brass cage, hence the starting performance is improved under high inertia and heavy load conditions [9][10][11][12]. Various researches on permanent magnet materials and rotor topology reveals that the LSPMSM provides enough asynchronous torque and high efficiency during synchronous operation but still, efficiency beyond IE4 is challenging with existing frame, material and motor manufacturing process [13][14][15][16][17]. LSPMSM offers the best performance for the radial type and novel hybrid interior rotor topology [18].…”

Emerging efficiency standards indicates the demand of implementing highly efficient motors to reduce energy consumption and global warming, which is a worldwide concern. Owing to this, IE4 Efficiency line start permanent magnet synchronous motors (LSPMSM) contribution is increasing to a greater extent in the industrial motor market. This paper presents a new rotor configuration for a 2.2kW, 4 pole LSPMSM which is designed to meet efficiency beyond IE5 along with good power factor. The steady state and transient performance of the motor is optimized by using finite element analysis (FEA) software. From the results, it is evident that the proposed motor meets beyond IE5 efficiency level with 10% reduction in its length. Further reducing the length up to 30%, the motor sustains at IE4 efficiency level. To illustrate the optimum performance of the proposed design, the performance of the motor is benchmarked with identical radial type LSPMSM and commercially available IE2 induction motor. The FEA results of the proposed design are validated with the prototype development and testing. Consequently, this topology is both technically competent and cost effective, particularly for round the clock operation.

“…The axial pole shaping of IPM machines to reduce the cogging torque as well as to obtain uniform distribution of flux density all over the surface is presented [17]. A hybrid rotor design, consisting of both circumferential as well as radial magnets, and having consequent rotor poles are also introduced to achieve an optimum synchronous performance of the motor [18]. But, the difficulties and expenses of manufacturing such kinds of rotors are very significant.…”

Introduction. At present, the most important requirement in the field of electrical engineering is the better utilization of electrical power, due to its increasing demand and not-so-increasing availability. A permanent magnet synchronous motor (PMSM) is increasingly gaining popularity in various household and industrial applications because of its superior performance compared to conventional electrical motors. Purpose. PMSM is designed based on the selection of various design variables and optimized to fulfill the same. Being superiorly advantageous over other motors, PMSM has the major disadvantage of higher cogging torque. Higher cogging torque generates torque ripple in the PMSM motor leading to various problems like vibration, rotor stress, and noisy operation during starting and steady state. The designer should aim to reduce the cogging torque at the design stage itself for overall better performance. Methods. An interior rotor v-shaped web-type PMSM is designed and its performance analysis is carried out using finite element analysis (FEA). Magnet v-angle is optimized with the objective of cogging torque reduction. Performance comparison is carried out between the optimized motor and the initially designed motor with FEA. Novelty. Magnet v-angle analysis is performed on the same keeping all other parameters constant, to obtain minimum cogging torque. The proposed method is practically viable as it does not incur extra costs and manufacturing complexity. Practical value. It is observed that the magnet v-angle is an effective technique in the reduction of cogging torque. Cogging torque is reduced from 0.554 N×m to 0.452 N×m with the application of the magnet v-angle optimization technique.

A Permanent Magnet Hysteresis Synchronous Motor (PMHSM) is designed and implemented in this paper. The designed motor is analyzed by using simulation and experimental studies. The torque, torque ripple, speed and flux density are also analyzed by using Finite Element Analysis (FEA) method. A standard commercial stator geometry is preferred for easy installation. A new rotor structure is designed for the motor. A submersible pump turbine is connected to the prototype motor in order to test under a real pump load condition by a pump test stand. The same pump used in the experiment was also tested with a commercial induction motor (IM) submersible pump motor with same power. Thus, the commercial and proposed motor are compared in terms of static head value, which is an important value in pump applications. The performance of the motor is better than the IM because it can operate at synchronous speed without slip. In addition, the proposed motor does not require any auxiliary system to achieve starting with grid. The proposed PMHSM can be used to obtain high performance and efficiency for pump applications.
