Special Issue Information

Dear Colleagues,

Electric vehicles use one or more motors to produce torque. Each motor is supplied with energy by dedicated electronic power converters. From a vehicle's builder's point of view, this is the car's powertrain. With various improvements, the motor and power converter are built in the same frame, reducing the cooling effort and minimizing noise and electromagnetic interference. Achieving this requires an interdisciplinary approach involving specialists in motor development, power converters, electronic control, sensors, liquid cooling systems, mechanics, and electromagnetic compatibility.

Welcome to this Special Issue, where we compile articles from specialists developing electric motors and drives for electric traction vehicles. This includes integrated solutions for small cars and distributed solutions for high-power vehicles such as trams, trolleybuses, electric buses, and trucks.

The most important characteristic of the electric drive components is efficiency as it has a major influence on a vehicle's autonomy, cooling effort, and temperature variation, which are the major challenges of vehicular components.

The second issue is the dynamic response of the electric drive to the driver's command and road condition reactions, thus making the electric-powered vehicle more friendly to the driver and safer on the road. This Special Issue aims to reveal this area's current efforts and progress.

You are welcome to submit a manuscript for this Special Issue. Academic researchers and authors from the industry involved in the field are invited to contribute original research articles and reviews.

Research areas may comprise (but are not limited to) the following:

  • Traction motor drives;
  • Traction motor;
  • Power converters;
  • Control and automation of electric-powered vehicles;
  • Sensors used in electric vehicle powertrains;
  • Batteries monitoring in automotive applications;
  • Fault diagnosis techniques for electrical powertrain systems;
  • Actuators for automotive applications.

The reliability of the EDS (Electric Drive System) in electric vehicles is crucial to overall vehicle performance. This study addresses the challenge of acquiring high-fidelity internal load data in the early development phase due to the absence of prototypes, overcoming the limitations of traditional road tests, which are costly, time-consuming, and unable to measure gear meshing forces. A method based on a VPG (Virtual Proving Ground) is proposed to acquire internal loads of a dual-motor EDS, analyze the impact of typical virtual fatigue durability road conditions on critical components, and generate load spectra for test bench experiments. Through point cloud data-based road modeling and rigid-flexible coupled simulation, dynamic loads are accurately extracted, with pseudo-damage contributions from eight intensified road conditions quantified using pseudo-damage calculations, and equivalent sinusoidal load spectra generated using the rainflow counting method and linear cumulative damage theory. Compared to the limitations of existing VPG methods that rely on simplified models, this study enhances the accuracy of internal load extraction, providing technical support for EDS durability testing. Building on existing research, it focuses on high-fidelity acquisition of EDS loads and load spectrum generation, improving applicability and addressing deficiencies in simulation accuracy. This study represents a novel application of VPG technology in electric drive system development, resolving the issue of insufficient early-stage load spectra. It provides data support for durability optimization and bench testing, with future validation planned using real vehicle data. Full article

Brushless DC motors are often used as traction motors in electric vehicles due to their high power density and efficiency. The dc-link electrolytic capacitor is the most vulnerable part of the brushless DC motor drive system, and it determines the reliability of the motor drive system. Therefore, it is of great importance to monitor the life of the dc-link electrolytic capacitor in the drive system. To carry out the lifetime monitoring of capacitors, a dc-link series switch circuit composed of diodes and power switching devices is introduced to calculate the capacitance value. The lifetime of the capacitor is then monitored in real time through this capacitance value. During normal steady-state operation of the motor, the control strategy of the inverter is switched. When the dc-link switch is turned off, the charging vector is used to charge the dc-link capacitor. Due to the presence of the diode and the dc-link switch, the energy charged to the dc-link by the motor can only flow into the capacitor and cannot be released immediately. Therefore, the capacitance value is calculated through the change in capacitor voltage and the capacitor current reconstructed from the three-phase currents of the motor. The feasibility of the method proposed in this paper is experimentally verified by building a brushless DC motor system. Full article

In this paper, a new fault-tolerant consequent-pole hybrid excited (FTCPHE) machine with toroidal winding (TW) is designed for electric vehicles (EVs). In this proposed machine, U-type permanent magnets (PMs) are adopted in the consequent-pole rotor with the sequence of PM–iron–PM–iron. The stator tooth placed in the stator is classified into two groups to achieve hybrid excitation. The TW is positioned on the stator yoke to achieve the simple structure and excellent fault-tolerant ability. First, the topology of this proposed FTCPHE machine with the TW is briefly introduced and compared to that with the traditional combined winding. Second, the operation principle, the magnetic circuit, and the design procedure of the FTCPHE machine are analyzed and illustrated. Third, several key structural parameters of the proposed FTCPHE machine are discussed and designed to improve electromagnetic performances. Next, some electromagnetic properties, including the flux distribution, the no-load back-EMF, the electromagnetic torque, the cogging torque, and the fault-tolerant ability, are discussed in detail. Finally, a prototype of this proposed FTCPHE machine is manufactured to validate the simulated results. Full article

Inductance is an important parameter for motor design and control, and the performance of the motor is closely related to the inductance parameter. To solve the problem of the complex magnetic circuit structure of search coil mutual inductance, this paper takes an 8-pole and 48-slot interior permanent magnet synchronous motor (IPMSM) as the object to carry out the relevant research on the formula of search coil mutual inductance, illustrates the method of calculating the mutual inductance of the search coil, and compares and verifies the proposed method through finite element analysis and the actual measurement results. By setting up a procedure for calculating the magnetic flux of the search coil, the magnetic flux of each sub-coil of the search coil is analyzed and calculated. The mutual inductance of the search coil is calculated by summing up the magnetic chains of different sub-coils between the phases of the search coil. Lastly, the finite element simulation of the permanent magnet synchronous motor (PMSM) with the placement of the search coil is carried out, the inductance of the search coil in the experimental prototype is measured practically, and the finite element simulation results of the mutual inductance of the search coil are compared with the actual measurement results, which proves the correctness of the theoretical analysis.
