“…So figure 6 (a,b,c) shows comparison of torque performance and phase voltage obtained from each case by examination (model 1), (model 2), (model 3). The performance is studied in each case by examination of torque, torque ripple, torque ripple frequency, speed of the rotor, and power factor, As shown in the following figures (7,8,9,10,11) However, Table 3 demonstrates the performance according to the mentioned metrics.…”

“…The operations of three-phase twelve poles induction motors are similar to the same of nine phases and higher pole number induction motors. The equivalent voltage profile coins of twelve poles, three-phase induction motor are formulated by participation of four pole-nine phases windings (winding per phase) [10].

Induction motors (IM) are used widely in high energy applications where high torque is required such as ships/ aircrafts manufacturing industry. Those motor drivers are populated in many advantages especially their wide control strategies. However, new technology is invented for enhancing efficiency and smoothing the torque curve by increasing number of phases in the motor drive. Speed control can be achieved by changing the pole numbers between any two different phases using pole-phase modulation (PPM). The problem is raised when a large number of phases are used to enhance the voltage profile. This problem is manifested in the complexity of control and complexity of hardware (more devices need to be involved) which increases the cost and degrades the performance. This paper argues using a multilevel inverter to produce an enhanced voltage profile and motor speed control without needing to increase the number of devices. The performance of the proposed model is compared with conventional models in terms of efficiency, power factor, speed, torque ripple, and ripple frequency. Results obtained using multilevel inverter based induction motors are found optimum.

“…As per the generalization of PPM [12]- [14] the number of stator slots (Q), number of phases (m) and number of pole pairs (P) are selected according to equation (1), subjected to the constraint that slots per pole per phase (q) must be same for all the pole phase combinations. The pole ratio k must be a positive odd integer ≥ 1 as given by equation (2) where P 1 is the lowest pole number for which the IM is wound for and P 2 is the next higher pole number to which machine operation is changed.…”

Pole phase modulated (PPM) multiphase induction motor (IM) drives for applications like ship propulsion starts with high pole mode of operation to provide high starting torque required and then switch over to low pole mode of operation for steady run with high speeds. The performance of the nine phase PPM IM drive in case of nine phase four pole operation is inherently good due to high phase number even with a two level inverter. In case of high pole mode of operation (3 phase 12 pole) of the PPM IM drive the torque ripple is not within the acceptable range of safe limits, which brings in the need of multilevel voltage excitation to achieve better performance. Conventional multilevel inverters for nine phase IM suffers with problems such as capacitor voltage balancing issues and considerably high device count. In case of three phase twelve pole operation of the PPM IM drive each phase voltage is the sum of voltage across the three equal voltage profile coils (EVPC). In This paper the advantage of EVPC is exploited to generate a multilevel voltage across each phase using phase shifted carrier PWM keeping the device count same as 2 level nine phase inverter. The effectiveness of the proposed scheme is shown by FEA simulation in ANSYS Maxwell and simplorer environment. Significant reduction in torque ripple magnitude and increase in torque ripple frequency is observed in case of 3 phase 12 pole operation.

Abstract:The pole phase modulation (PPM) technique is an effective method to extend speed range and torque capabilities for an integrated starter and hybrid electric vehicles applications. In this paper, the five pole-phase combination types of a multiphase induction motor (IM) with 36 stator slots and 36 stator conductors are presented and compared quantitatively by using the time-stepping finite element method (TS-FEM). The 36 stator conductors of the proposed multiphase IM are fed by a 36 leg inverter and the current phase angle and amplitude of each stator conductor can be controlled independently. This paper focuses on the winding connection, the PPM technique and the performance comparative analysis of each pole-phase combination types of the proposed multiphase IM. The flux distribution, air-gap flux density, output torque, core losses and efficiency of five pole-phase combination types have been investigated.
