“…The tensile strength and interlaminar shear strength of the sample at each level were calculated, respectively, according to Equations ( 1) and (2). The average value of the calculated results of multiple groups at each level was obtained, and the dispersion coefficient was calculated according to Equation (3). The obtained data are plotted in Tables 4 and 5.…”

“…Two kinds of sleeves are commonly used, namely metal sleeves and composite sleeves. Among them, carbon fiber composite protective sleeves have the following advantages: they have weak conductivity, which reduces eddy current losses in the sleeve [3]; they also have low density, which increases motor power density; additionally, they have higher strength and require less thickness than other materials, maximizing the actual air gap of the motor and creating possibilities for electromagnetic coil design [4]. There are many scholars who have studied the composite sleeving of high-speed permanent magnet motors.…”

Surface-mounted high-speed permanent magnet motors are known for their small size, high power factor, and reliable control and operation. However, these motors may have low mechanical strength and weak tensile strength in their rotor magnet, which necessitates the adoption of an external sleeve for protection. Currently, carbon fiber composite sleeves are garnering increasing attention for their durable and reliable protective capabilities. Despite the apparent benefits of carbon fiber composite protective sleeves, systematic research on the relevant parameters such as winding angle, fiber type, resin type, winding tension, and curing method is currently lacking in the literature for high-speed permanent magnet motors. In this context, this paper employs an innovative approach, utilizing the Taguchi method, the National Ordnance Laboratories (NOL) ring failure test, and a resin content test, to investigate the winding process parameters of carbon fiber composite protective sleeves for high-speed permanent magnet motors. The results indicate that the tensile strength of the composite sleeve with a winding angle of 45 and 30° is reduced by 20~25% compared with the sleeve with a pure hoop winding angle. The loss of strength caused by the manufacturing process accounts for 30%. When the wet winding tension is 130 N, the tensile and shear strength of the sleeve decreases by 13 and 12%, respectively, compared with that of 70 N. When the dry winding temperature rise rate is 3 min/°C, the strength of the sleeve decreases by 16% compared with that of 1 min/°C. For a small-thickness sleeve with a thickness of 1.5 mm, two-layer curing can increase the tensile strength of the sleeve, while three-layer curing or more can decrease the strength. By studying the process parameters of the sleeve, this article prepared a composite sleeve for a high-speed permanent magnet motor with a line speed of 200 m/s. This study provides a comprehensive analysis of the manufacturing process parameters of the rotor sleeve, which is helpful for the design and performance optimization of high-speed permanent magnet motors.

“…Ferrite magnets, in particular, have low magnetic coercivity and are sensitive to demagnetisation [12]. Additionally, surface-mounted magnets cannot withstand high centrifugal forces, so a sleeve is needed to hold the magnets in place at higher speed ranges [185,186]. A study on alloy and carbon fibre sleeves found that when a constant mechanical air gap length is adopted, the decrease in the sleeve thickness would significantly increase the air gap magnetic flux density and stator iron loss.…”

“…A study on alloy and carbon fibre sleeves found that when a constant mechanical air gap length is adopted, the decrease in the sleeve thickness would significantly increase the air gap magnetic flux density and stator iron loss. In addition, as the sleeve thickness increases, the rotor eddy current loss and rotor temperature increase too [186]. Furthermore, the sleeves directly affect the disassembling process of the electric machine.…”

Innovative technological solutions have become increasingly critical in addressing the transportation sector’s environmental impact. Passenger vehicles present an opportunity to introduce novel drivetrain solutions that can quickly penetrate the electric vehicle market due to their shorter development time and lifetime compared to commercial vehicles. As environmental policy pressure increases and customers demand more sustainable products, shifting from a linear business approach to a circular economy model is in prospect. The new generation of economically competitive machines must be designed with a restorative intention, considering future reuse, refurbishment, remanufacture, and recycling possibilities. This review investigates the market penetration possibilities of permanent magnet-assisted synchronous reluctance machines for mini and small-segment electric vehicles, considering the urban environment and sustainability aspects of the circular economy model. When making changes to the materials used in an electric machine, it is crucial to evaluate their potential impact on efficiency while keeping the environmental impact of those materials in mind. The indirect ecological effect of the vehicle’s use phase may outweigh the reduction in manufacturing and recycling at its end-of-life. Therefore, thoroughly analysing the materials used in the design process is necessary to ensure maximum efficiency while minimising the environmental impact.
