The complex vector decoupling control (CVDC) can achieve complete decoupling when the proportional coefficient ($k_{p}$) and the integral coefficient ($k_{i}$) of the current loops meet a certain proportion. But in most occasions, the $k_{p}$ and $k_{i}$ are out of that proportion, leading to incomplete decoupling. Thus, an improved complex vector decoupling control (ICVDC) is proposed. Based on the traditional CVDC, the current compensation is introduced to improve decoupling performance. The simulation results demonstrate the effectiveness of this method. Furthermore, the system shows good dynamic response performance and strong robustness.

The computation of end-winding leakage inductance is often an expensive task during the design process of electrical machines, but still important for an accurate estimation of the expected short circuit current of the evaluated design. Since commonly used 3D finite element analysis (FEA) based approaches require complex modelling and consist of time consuming solving, they are less suitable for a fast evaluation. Alternatively, methods based on the Neumann-Integral can decrease the calculation time and reduce the model complexity, but suffer from the requirement of numerical integration. This paper presents an enhanced approach, based on the partial element equivalent circuit (PEEC) method, to estimate the end-winding leakage inductance by applying closed form analytical solutions for fundamental PEEC cell geometries to arbitrary hairpin winding configurations. To emphasize the benefit and the merits of the proposed approach, a study case traction motor is analyzed and the results are compared to complex 3D FEA and measurements by evaluating the short circuit current. Finally, the approach is used to estimate the influence of short pitchening on the end-winding leakage inductance.

A novel electrohydraulic energy converter for hybrid off-road machines is presented. The converter is utilized as a power source for hydraulic actuators enabling electrical energy recuperation. The authors have designed, built and tested a device which combines a 7 kW S3 70% electric motor, a planetary gear and a bent-axis hydraulic pump. The integration aims for a power dense small volume device, which can perform the load cycles e.g. of a log stacker. The load cycles are first simulated to define design boundaries for the motor design. The motor uses a moderate amount of oil inside motor chamber as heat transfer medium bringing the motor losses to the converter outer surfaces to be then dissipated in the ambient. The converter is attached to a log loader and real load-cycle performance is investigated. Real load cycles for a log loader are recorded, the converter performance and thermal behaviour are studied. Motor thermal behaviour and losses are studied with no oil or with a moderate amount of oil in the motor. The converter prototype cleared well the requirements in the load cycles tested.

Nowadays, stepper motors are extensively used in positioning applications due to excellent open-loop accuracy and a relatively simple control principle. Every time the controller sends a step-command pulse to the motor, the rotor will move for a known discrete angle. By subsequently counting the number of pulses, the rotor angle is known at all times. Nevertheless, due to the control principle's nature, as a matter of safety, the bulk of stepper motors are often not driven at their full potential to prevent so-called step-losses. Typically, this results in low energy efficiency and an over-dimensioned motor. As a solution, maximizing the motor's load potential through intelligent algorithms contributes to smaller motors and increases efficiency since higher motion speeds are reachable. Until now, in search of optimal motor usage for point-to-point motion profiles, literature mainly focused on finding time-optimal motion profiles using simplified models with a complicated analytical approach rather than developing an easily executable methodology that optimizes at the fundamental control level. Therefore, this paper presents a novel optimization methodology, solely based on the motor's load angle, of which the resulting puls commands' timings can be easily deployed in commercial stepper motor drives. Results show a significant improvement in time-saving of 36,45% compared to a reference 5th-order polynomial point-to-point trajectory.

Magnetically-levitated drives are interesting in applications which demand a combination of reliable operation and high speeds. In the latter domain, slotless stators are recognized as the most suitable, as they deliver higher power density and lower speed-dependent losses. Nevertheless, the larger airgaps proper to slotless topologies minder bearing load capacities. In this study, a slotless and slotted drive designed for the same rotor are experimentally characterized. They are compared head-to-head in terms of passive stiffnesses and torque and force generation. A bearing control effort factor is also defined.

In this paper, a novel methodology for the design optimization of permanent magnet synchronous machines (PMSM) is presented. It is applied to an outer rotor machine for an unmanned aerial vehicle (UAV). The study shows how, considering all points (up to several thousands) of a working cycle torque/RPM, it is possible to optimize both geometry and control strategy, with the objective of weight and losses minimization while keeping a reduced computational time. With this kind of applications, the working points can have a big variation, which requires a specific method to avoid oversizing and to control multiple constraints in the same time. Hence, the temporal thermal variation is calculated, taking into account the transient. The magnetic saturation, geometrical and electrical constraints are also considered along the working cycle. The electromagnetic model is presented and validated by finite element analysis (FEA).

Bearing currents are stressing industrial drives which include switching power supplies. Researchers frequently propose new countermeasures. One of the promising approaches is the reduction of parasitic capacitive couplings inside an electrical machine. Slot-opening-embedded electrostatic shields are considered a viable concept. In this work, a way to further increase the effectiveness of the approach is presented. The importance of taking the end windings into account is recalled, and a design of extended slot-opening-embedded electrostatic shields that cover also the winding overhangs is studied. The effect of the suggested extension is examined via modeling electric machines with different power ratings. In addition, the paper closes the knowledge gap of the scaling behavior of the previously introduced capacitive coupling elimination technique, based on the slot-opening-embedded grounded electrode.

This paper presents the design, modeling, and numerical performance evaluation for a novel type of high-torque motor, targeting various direct-drive applications such as robot actuator, precision motion rotatry stages, and in-wheel drive for electrical vehicles. The key idea of the motor design is to use a combination of (a) combined axial- and radial-flux electric machine and (b) vernier permanent magnet (VPM) motor. Such combination effectively increases the torque generation capability for the proposed motor, and makes it attractive for direct-drive applications. Analytical model for the motor's performance is derived and is validated using finite element method (FEM), and is used for optimizing the motor design parameters. Motor's losses and efficiency are evaluated by FEM simulations for various magnetic material selections. The mechanical design for the motor is also discussed. The simulation result of the proposed motor demonstrates a 1.5× torque improvement compared with a baseline off-she-shelf direct-drive machine of the same size. The comparison shows that the proposed machine design is promising for the next-generation high-torque direct-drive motors.

In this paper, a novel sinusoidal pulse width modulation (SPWM) strategy with simple implementation is proposed for an open-winding machine fed by isolated DC-bus dual two-level three-phase inverters to reduce PWM switching frequency and current harmonics. A novel zero sequence voltage injection method is injected to the reference voltage of dual inverters in this strategy to reduce current harmonics and improve the voltage utilization of SPWM strategy. Moreover, an unbalance reference voltage distribution method is applied to generate different reference voltages for two inverters. In the proposed strategy, only three of six legs of dual inverters are switched in a PWM cycle, and thus the switching frequency is halved, while the current harmonic characteristic can be improved, compared with the conventional SPWM strategy. The superiority of the proposed SPWM strategy is validated by simulation and experiment results.
