“…To resolve the problem, a detailed thermal analysis is required for the dual-rotor PM motor to establish the copper loss and iron loss model [61]. On the base of the loss model, the temperature distribution of the whole motor can be calculated, through which a special type of forced air cooling system is designed to improve the heat dissipation of the dual-rotor PM motor [62,63]. For the inner air gap of the motor, since the PM rotor (outer rotor) and armature rotor (inner rotor) rotate at the same time and their speeds are different, position decoupling is the key to the control strategy and algorithm.…”

Abstract:The paper presents a number of advanced solutions on electric machines and machine-based systems for the powertrain of electric vehicles (EVs). Two types of systems are considered, namely the drive systems designated to the EV propulsion and the power split devices utilized in the popular series-parallel hybrid electric vehicle architecture. After reviewing the main requirements for the electric drive systems, the paper illustrates advanced electric machine topologies, including a stator permanent magnet (stator-PM) motor, a hybrid-excitation motor, a flux memory motor and a redundant motor structure. Then, it illustrates advanced electric drive systems, such as the magnetic-geared in-wheel drive and the integrated starter generator (ISG). Finally, three machine-based implementations of the power split devices are expounded, built up around the dual-rotor PM machine, the dual-stator PM brushless machine and the magnetic-geared dual-rotor machine. As a conclusion, the development trends in the field of electric machines and machine-based systems for EVs are summarized.

“…Although some work has been done on TC actuators such as in [10], [11], [12], and [13]; not much has been done to transduce the electric to kinetic energy with high efficiency using an experimentally validated multiphysics simulation finite element method (FEM) model. The importance of taking into account thermal and mechanical features in addition to electromagnetic features has been shown in [14]. The focus of this paper is on the energizing source that is suitable for each of the studied actuators while taking into consideration the stroke requirements.…”

“…As a result, the inaccurate results cannot meet the desirable requirements. To obtain accurate results, the iterative parameter method is analyzed in [19], which can efficiently improve the accuracy of results, as the parameter needs to be calculated through multiple iterations in the simulation program. However, the simulation process involves 2D and 3D simulations, which are inconvenient, especially for the complex motor structure.…”

Flux-switching permanent magnet (FSPM) motors have gained increasing attention in electric vehicles (EVs) applications due to the advantages of high power density and high efficiency. However, the heat sources of both permanent magnet (PM) and armature winding are located on the limited stator space in the FSPM motors, which may result in the PM overheating and irreversible demagnetization caused by temperature rise, and it is often ignored in the conventional thermal analysis. In this paper, a new electrical-thermal two-way coupling design method is proposed to analyze the electromagnetic performances, where the change of PM material characteristics under different temperatures is taken into consideration. First, the motor topology and design equations are introduced. Second, the demagnetization curves of PM materials under different temperatures are modeled due to PM materials are sensitive to the temperature. Based on the electrical-thermal two-way coupling method, the motor performances are evaluated in detail, such as the load PM flux linkage and output torque. The motor is then optimized, and the electromagnetic performances between initial and improved motors are compared. Finally, a prototype motor is manufactured, and the results are validated by experimental measurements.
