“…The drive force is designed to be no less than the maximum static friction force. The drive motor is a type of PMSM, which is widely applied in construction machinery [28,29], with a rated torque of 1200 Nm, and the parameters are listed in Table 13. The transmission ratio from the motor to the wheel of the rear drive axle is 22.85.…”

The electric wheel loader is a new prototype in powertrains and drivetrains that saves energy consumption and diminishes emissions as earthmoving machinery. Dual-motor drive in the front and rear axles of electric wheel loaders helps the distribution of drive torque. However, challenges arise during shoveling conditions, particularly when one motor generates torque exceeding the ground’s adhesion force, leading to tire slippage. This study thoroughly examines the mechanical structure of the working unit and elucidates the correlation between wheel load and hydraulic pressure in the base chamber of the tilt cylinder. This analysis is accomplished through a combination of theoretical derivations and experimental tests. The experiments involve a 5 ton rated load electric wheel loader tested across five running cases as well as weighing tests on a 15 ton rated load electric wheel loader. Based on the experiment discoveries, a dual-motor drive electric wheel loader is designed with specific transmission ratios for the front and rear drivetrains, and a torque distribution strategy is proposed based on wheel load during shoveling. Running condition tests demonstrate sufficient drive force for the new electric wheel loader, and shoveling tests reveal a significant reduction in tire slippage when employing the proposed torque distribution strategy compared to evenly distributed torque in the front and rear axles. Moreover, the driving force during the shoveling process remains undiminished. This indicates that the newly designed loader, in conjunction with the proposed strategy, exhibits excellent shoveling efficiency.

“…The escalating focus on transportation electrification stems from its pivotal role in mitigating urban pollution concerns, where advanced electric motor systems play a central role. In the realm of electrified transport, the design of electric motors and their associated drive systems must prioritize high power density, efficiency, and reliability [1][2][3][4][5][6][7][8]. This emphasis becomes critical due to the typically restricted volume and weight allowances in electric vehicles (EVs).…”

Permanent magnet motors (PMMs) have emerged as key components in numerous industrial applications due to their high efficiency, compact size, and robust performance characteristics. However, to attain optimal performance in PMM drives, accurately predicting and mitigating core losses is paramount. This paper aims to provide a comprehensive review of advancements and methodologies for enhancing the performance of PMM drives by integrating equivalent circuit models (ECMs) that account for core losses. Firstly, the significance of core losses in motor drives is underscored, alongside a survey of research endeavors dedicated to core loss reduction. Notably, emphasis is placed on mathematical models offering both swift computation and reasonable accuracy. Subsequently, the paper delves into the development of ECMs, focusing on approaches adept at capturing core loss effects across diverse operating conditions. Moreover, this paper explores the utilization of these improved ECMs in the design and control of PMMs to achieve enhanced performance. By integrating core loss considerations into design and control strategies, PMM drives can optimize efficiency, torque production, and overall system performance. In summary, this paper may consolidate the current state-of-the-art techniques for enhancing PMM performance through the integration of core-loss-aware ECMs. It highlights key research directions and opportunities for further advancements in this critical area, aiming to foster the development of more efficient and reliable PMM-based systems for a wide range of industrial applications.

This article discusses the issue of production a motor-wheel for prototypes of mini-electric vehicles based on new soft magnetic materials. The structure and morphology of the surface obtained composite materials have studied. The density value calculated from the X-ray diffraction data is about 3% higher than the directly measured values, which are 7.7 g/cm3. Technologies and create new technical means and their effective use, the results of development and research of magnetic materials and complex technology for constructing electric motors based on them are disparate and do not allow the creation of new approaches for their mass implementation. Tests of the electromagnetic characteristics of magnetic circuits based on the materials obtained for constructing an electric drive were carried out using an express magnetometer.
