“…A seamless transition between these two methods is achieved with a single position estimator. The estimated position can successfully integrated into the torque ripple reduction control presented in [5]. In addition, the experiment results demonstrate that with the proposed sensorless control, the machine can start up with a 50% rated load.…”

“…The structure of DCFSMs is rugged since the armature and field windings are located in the stator slots. Moreover, literatures have reported that single-phase DCFSMs exhibit higher efficiency [1][2][3][4] and lower torque ripple [5] than other type of single-phase machine, e.g. single-phase induction machines (IMs), universal machines (UMs), and single-phase brushless dc machine (BLDC).…”

“…In general, torque ripple of single-phase DCFSMs is greater than 100% because of the commutation of armature current. A torque ripple reduction scheme was presented in [5], and it was implemented on the single-phase DCFSM with a two-layer rotor presented in [10]. This machine exhibits a complementary torque characteristic due to the two-layer rotor structure.…”

Single-phase dc-excited flux-switching machine (DCFSM) exhibits low manufacturing cost and rugged structure. This type of machine has better efficiency and torque density than single-phase induction machine and universal machine. In addition, single-phase DCFSM can generate lower torque ripple than other types of single-phase machines, e.g. switch reluctance machine and brushless DC machine. These advantages make it suitable for low-cost variable speed applications. However, single-phase DCFSMs requires accurate position feedback from a position sensor to generate smooth torque. The position sensor such as an encoder is not permitted in the low-cost applications due to its high cost. To eliminate the position sensor, this paper presents a novel sensorless control scheme for single-phase DCFSMs. Rotor position is estimated with the position-dependent armature current ripple induced by injecting high-frequency square-wave voltage to the field winding at standstill and low speeds. At medium and high speeds, armature mutual flux linkage is calculated and used to estimate the rotor position. A seamless transition between these two methods is achieve by mixing the calculated position error signals as the input for a single position estimator. The experimental results show that with the proposed scheme, the single-phase DCFSM can accelerate from standstill to the rated speed with 50% load, and to the maximum speed with 25% load, respectively.INDEX TERMS DC-excited flux switching machine; single-phase machine; sensorless control; flux linkage estimation; high-frequency voltage injection.

The paper presents the results of FEM 2D computational studies of a three-phase Direct Current Excited Flux Switching Machine (DCEFSM) electric motor with rotor teeth and stator teeth. The aim of the research was to minimize the cogging torque of the machine by changing the geometry of the rotor teeth and the size of the air gap between the stator and the rotor, with the operating torques unchanged. Computational studies were carried out on the influence of the width of the rotor teeth, the radius of the rounding of their corners, and the size of the air gap on the cogging torque and machine operating torques. The results of the calculations made it possible to select the dimensions of the rotor and the air gap in such a way that the maximum cogging torque was reduced more than six-fold, with the machine operating torques being unchanged. The calculations also showed that it is not possible to increase the value of the operational torques by further changes in the geometry of the rotor teeth and the size of the air gap of the machine.

Flux switching Motor (FSM) was invented in the 19 th century but started gaining importance after 2000. The simple structure and moderate cost of FSM, in comparison with existing commutated Direct Current (DC) and Permanent Magnet Brushless Direct Current (PMBLDC) motors, have made it attractive for contemporary applications. Currently, FSM is employed in research applications like automobiles, domestic appliances, power generation, etc. To make FSM a viable candidate for these applications, modifications are made to the design, power converters, and control systems of FSM. This article comprehensively reviews the various control topologies adopted for FSM, which encompasses the control of torque and speed. Different control algorithms like 1) linear controllers, 2) sensorless techniques, 3) predictive controllers, and 4) optimization techniques are discussed extensively based on existing literature. Further, a case study is carried out using these control algorithms, and the simulation results are analyzed.
