“…In‐wheel motors: The in‐wheel motor used in EVs has required more attention. It offers simple structure, flexible control, and high transmission efficiency also reduces weight and clears space in the car [89]. Since it should be mounted inside the wheel, its size and structure are limited by the characteristics of the wheel and the EV.…”

Printed circuit board (PCB) motors are witnessing increased interests and applications in the scientific communities and industry thanks to the advantages of compact size, high power density and efficiency, design flexibility, and low manufacturing cost. PCB has become a feasible and appropriate alternative to conventional round‐wire winding. It is applicable to any kind of electrical machines, such as axial‐flux machines and radial‐flux ones, in many applications. Moreover, it improves electromagnetic and thermal performances, which is affected by some design choices and winding arrangements. This study provides a comprehensive review of the PCB motors including the various aspects of initial electromagnetic design, performance analysis, winding arrangements, PCB coil design, and applications of PCB motors. Key references on the abovementioned aspects pertaining to the motor are discussed. Thus, offering researchers and engineers the most up‐to‐date information on the developments and progresses with the PCB motor design and technology.

“…In the scenarios evaluated in simulations, the authors suggest a 40% increase in comfort and safety in relation to the passive damping system. Bičeka et al (2019) evaluates commercial IWM technology in Ingress Protection (IP) tests. The results show that the solution reaches levels with IP68 and IP6k9k, resisting high pressure jets and submersion of up to 1 m. The authors also conclude that the evaluated IWM technology can operate on ambient temperature of -40 to 85 • C without damage to the lifespan.…”

“…It is noticeable that there are several solutions for applications in conventional vehicles, such as for personal use and transportation, and the available solutions are robust to critical conditions due to humidity, dust, ice, mud, as well as mechanical impacts, vibrations and mechanical stresses on the three axes (Bičeka et al, 2019). For performance vehicles, such as the Formula Student, the torque and power density indices are even more relevant.…”

This paper discusses in-wheel electric tractive systems, bringing as a case study the finite element design of a Fractional Slot Permanent Magnet Synchronous Machine with non-Overlaping Winding (FSPMSM) for an all-wheel drive Formula Student powertrain. The goal is to obtain a system that fits a 10” rim wheel, with a high power density that enables a 280 kg vehicle to accelerate over 75 meters in less than 4 seconds. Iterating the design method to maximize the output torque, the simulations indicate that a single 12,000 rpm machine can provide continuous 17.7 kW at the 600 Vdc system.

“…Efforts to reduce these negative effects accompanied by requirements of national and international regulations forced the automotive industry to develop and promote more energy and environmentally efficient concepts of how to power road vehicles. Due to these tendencies, research and development activities have been intensified in the field of hybrid electric vehicles (HEVs), fuel cell vehicles (FCVs) and battery electric vehicles (BEVs), hence numerous researchers have been engaged in developing transmission [1,2], suspension systems [3,4] electric motors [5,6], in generation of driving cycles [2,7] and in studies related to other areas of automotive engineering.…”

In order to reduce the greenhouse effect caused by CO2 emissions, a lot of car manufacturers are developing battery electric vehicles (BEVs). Almost all of these vehicles have a traditional powertrain layout with the drive unit located in the car body. However, in recent years, a new technology called in-wheel motors has appeared. It significantly improves handling and manoeuvrability of vehicles but it also presents a challenge for both researchers and manufacturers. Since the motors are fitted into a limited space, they must provide high torque and high efficiency. When a reducer is used, the amount of torque needed is decreased several times, hence the overall dimensions of the motor are reduced. This paper studies a number of issues such as the basic concepts of the in-wheel hub drive systems, traction balance, preliminary gear ratio and possible design solutions for reducers used in in-wheel hub drive units. Characteristics of single-stage planetary and cycloidal reducers are analysed in detail. The results show that planetary reducers have an advantage if a lower gear ratio is needed.
