“…Wind energy, a prevalent type of clean energy in daily life, [1,2] is harnessed through methods such as electromagnetic generators (EMGs) [3,4] and triboelectric generators (TENGs). [5,6] EMGs generate electricity using components like magnets and coils, resulting in a larger size and more complex structure.…”

Disc and cylinder‐based triboelectric nanogenerators (TENGs) have great potential for harvesting wind energy. However, a significant challenge faced by these TENGs is the wear issues arising from the required close contact between tribo‐materials, especially at high frequencies. In response to this challenge, a gear‐slider TENG (GS‐TENG) is designed to transition from continuous close‐contact friction mode to intermittent contact. Working in unison with the central gear and two sliders, four units housed within GS‐TENG yield electrical output through periodic contact and separation. During a durability test of 845 000 cycles, the short‐circuit current only experiences a slight decrease, going from 25.38 to 24.03 µA, retaining 94.68% of its initial value. Operating at a matched impedance of 6 MΩ, GS‐TENG at M1 achieves a peak power density of 386 mW m−2, exceeding some previously proposed solutions in wind harvesting. When integrated into a wind speed sensing system, the GS‐TENG has a wide sensing range (13.1 to 28 m s−1) with a maximum error of 3.39%. This work demonstrates a rotation‐to‐translation strategy that lays the foundation for long‐term, high‐frequency wind energy harvesting and the development of a self‐powered wind sensing system.

“…Therefore, in order to avoid the demagnetization of PMs, the neodymium PMs of the proposed outer rotor generator are sandwiched between the rotor segments, which have a much lower temperature compared to the stationary parts. In addition, the ferrite PMs, which are strong at high temperatures, are located in the stator yoke [17,18]. The proposed generator, known as the double permanent magnet excited flux switching generator (DPME-FSG), incorporates both ferrite and neodymium PMs in the stator yoke and rotor segments, respectively.…”

An outer rotor double permanent magnet (PM) excited flux switching generator is designed and optimized in this paper for direct drive wind turbine applications. This generator consists of two sets of PMs: ferrite PMs embedded in the stator yoke and neodymium PMs sandwiched between the rotor segments. In this regard, the main justification for employing ferrite PMs in the stator yoke is that the risk of demagnetization of ferrite PMs at high temperatures is lower than that of neodymium PMs (the temperature of the machine's stationary parts is higher than that of its rotating parts). For the design of the machine, the Taguchi design of experiments is deployed, while a decision-making algorithm based on the technique for order of preference by similarity to the ideal solution is used to solve the contradiction that results from the Taguchi design of experiments in the multi-objective design optimization process. During the multi-objective design optimization steps, simultaneously maximizing the no-load phase voltage and minimizing the cogging torque and total harmonic distortion of the no-load phase voltage are defined as the objective functions. The optimally designed machine is prototyped
