“…The studied AFIM is a capacitor‐run single‐phase motor, which can be used as an evaporative cooler motor. As mentioned in [46], for applications where efficiency and reliability are more important measures than torque pulsations, single‐phase motors are generally a good choice. The motor is designed with a single‐squirrel cage rotor and a slotted stator.…”

The aim of this study is to find out the performance characteristics of single-phase axial flux induction motors. In this study, three-dimensional time-stepping finite-element method is employed to analyse electromagnetic fields. Both eddy current and saturation effects are considered in the simulation. Since this transient solution is a computationally expensive method, a mathematical model based on d−q-axis theory is presented in this study. Then, the motor's electrical parameters, whose values are requested in the d−q model, are calculated using the analytical method and the DC-charge test of the built motor. The comparison between experimental and simulation results verifies the success of simulation.

Modelling techniques are proposed for describing a two-phase axial-flux brushless motor in a direct-drive electric vehicle. Similarity transformation and singular value decomposition (ST-SVD) methods are used to linearize the system model. Stationary and cosecant coordinate models are derived on the basis of the methods proposed. Decoupled inductances and constant torque relations are also obtained. The model proposed is a very useful aid in describing the system dynamics. Simulation and experimental results are illustrated to verify the validity of the model. The given system modelling techniques can provide valuable mathematical models for associated vector control.

A multisectional power driver design for the two-phase linear brushless motor will be proposed in this paper. The field-oriented modeling of the axial-flux linear brushless motor (AFLBM) will also be developed by using stationary and cosecant similarity transformation and singular value decomposition. Stationary and cosecant coordinate models will be derived based on the proposed approach. Decoupled relation and constant torque property will be obtained from the proposed models. Switching logic table for the linear motor operation is provided to drive the AFLBM properly. The switching-mode analysis for the power driver is also analyzed in detail. In order to increase the efficiency and the effectiveness of the electric motor applications, a multisectional driver circuit, which features the power driver with the so-called N + 2 structure, will be investigated and compared. Experimental results show that the proposed circuit design can achieve better performance with the higher efficiency. It is believed that the proposed driver circuit technique and system modeling can be very helpful to the control of railway transportations.Index Terms-Axial-flux linear brushless motor (AFLBM), blocking diode, cosecant model, multisectional power driver, power driver with N + 2 structure, similarity transformation (ST), singular value decomposition (SVD), stationary model.
