“…These types of machines are widely used in proportioning devices, synthetic-fibre manufacturing industries, wrapping and folding machines, positioning of control rods in nuclear industries, industrial drive systems requiring synchronized and continuous processes. Potential use of such machines for traction purposes is also reported [101][102][103].…”

This paper presents current research trends and prospects of utilizing additive manufacturing (AM) techniques to manufacture electrical machines. Modern-day machine applications require extraordinary performance parameters such as high power-density, integrated functionalities, improved thermal, mechanical & electromagnetic properties. AM offers a higher degree of design flexibility to achieve these performance parameters, which is impossible to realize through conventional manufacturing techniques. AM has a lot to offer in every aspect of machine fabrication, such that from size/weight reduction to the realization of complex geometric designs. However, some practical limitations of existing AM techniques restrict their utilization in large scale production industry. The introduction of three-dimensional asymmetry in machine design is an aspect that can be exploited most with the prevalent level of research in AM. In order to take one step further towards the enablement of large-scale production of AM-built electrical machines, this paper also discusses some machine types which can best utilize existing developments in the field of AM.

This study presents the evaluation of performance indexes of a novel synchronous reluctance motor (NSynRM) that has an axially sinusoidal rotor lamination shape. The stator of a 5.5 kW, 4-pole, 50 Hz conventional three-phase squirrel cage induction motor, with distributed and chorded by one slot, double-layer winding, is used for both standard and NSynRMs. Owing to the nature of the sinusoidal rotor structure, the three-dimensional finite element analysis (FEA) is utilised to study the electromagnetic parameters of interests. The NSynRM with sinusoidal rotor shape results is compared with the standard SynRM without cutoff on the q-axis. The FEA results are validated by means of practical measurements.

“…The novel lamination concept for transverse flux machines suitable for direct drive application to EVs is presented in [8]. SynRMs utilize for torque production the reluctance concept and rotating sinusoidal magneto-motive force (MMF), which are produced by the traditional induction machine stator [4]. The stator can be exactly the same as the induction machine and the rotor is simple and robust formed only by steel laminations.…”

This paper analyses the effect of rotor barrier pitch angles on torque ripple production in Synchronous Reluctance Machines (SynRMs), with the objective to reduce torque ripple contents in medium size ground Electric Vehicles (EVs). While keeping major-design parameters constant, the barrier pitch angle is varied by a quarter of the stator slot pitch. Three SynRMs having different rotor barrier pitch angles are designed and modeled using 2D Finite Element Method (FEM). The specifications of a traditional 5.5 kW, three-phase, 50 Hz, induction machine are used to design and model the SynRMs. Torque ripple reduction of ± 48 % is achieved for barrier pitch angles of 15 o and 17.5 o mech, when the machines operate at current space phasor angle of 45 o electric.
