ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.A lightweight hybrid backpack integrating SC‐TENGs and R‐EMGs harvests biomechanical energy during walking. With a low activation speed of 3 km h−1 and a high specific power of 0.18 W kg−1, it enables self‐powered field safety management. The power backpack refers to an energy‐harvesting solution engineered to mitigate battery reliance in wearable ...

Reduction of Cogging Torque in Permanent Magnet Motors
Journal of the Magnetics Society of Japan, 2007 EPS (Electric Power Steering) enables an increase in automotive fuel efficiency by 3-5% and contributes to the protection of the environment by eliminating the oil medium used in conventional hydraulic power steering. For this reason a sharp increase in demand for EPS is expected.

Cogging Torque Reduction Techniques for Spoke-type IPMSM
IOP Conference Series: Materials Science and Engineering, 2017 A spoke-type interior permanent magnet synchronous motor (IPMSM) is extending its tentacles in industrial arena due to good flux-weakening capability and high power density. In many of the application, high strength of permanent magnet causes the undesirable effects of high cogging torque that can aggravate performance of the motor. High cogging torque

Journal of Diabetes, Volume 18, Issue 10, October 2026.Older drivers with T2DM show significantly longer braking times compared to those without diabetes, regardless of the presence of peripheral neuropathy based on the Michigan Neuropathy Screening Instrument. Female sex and reduced plantar flexor strength predict poorer braking performance.

A Study on Core Skew Considering Manufacturability of Double-Layer Spoke-Type PMSM
Energies, 2021 The spoke-type permanent magnet synchronous motor (PMSM), which is a general ferrite magnetic flux-concentrated motor, has a low portion of reluctance torque at the total torque magnitude. Therefore, as a way to increase the reluctance torque, there is a
