ABSTRACT People with physical disabilities face significant mobility challenges while climbing uneven surfaces and staircases. In these circumstances, traditional wheelchairs do not provide stable, safely controlled mobility, underscoring the importance of building superior stair‐climbing wheelchairs for both medical and infrastructure purposes.

Cogging Torque Minimization Strategies in Interior Permanent Magnet Synchronous Motors
Cogging torque in interior permanent magnet synchronous motors (IPMSMs) is caused by variation in magnetic reluctance between permanent magnets and stator slot openings.

Study of Methods for Cogging Torque Reduction in Permanent Magnet Machines [PDF]
To propose the methods for cogging torque reduction in permanent magnet machines, theoretical reasons of cogging torque are studied in this paper and the qualitative analysis is performed before quantitative calculation with finite-element method. And the effects of slot opening widths, unequal thickness magnets as well as pole-arc factors on cogging ...

A coil‐based soft sensor is presented for auto‐adaptive control of bioinspired dry adhesive robotic end‐effectors. The sensor enables misalignment detection during continuous motion and discriminates planar and convex surface geometries. Integrated into activated adhesive structures, the system achieves high angular accuracy and robust object ...

Modification of Pole Pitch and Pole Arc in Rotor Magnets for Cogging Torque Reduction in BLDC Motor
Cogging torque is an unfavorable hindrance in Permanent Magnet Brushless DC (PMBLDC) motor. In medium-low power PMBLDC motors, the surplus oscillations and intolerable noise happen because of the harmonic magnetic forces created by cogging torque.

Embryonal Paratesticular Rhabdomyosarcoma Masquerading as an Inguinal Hernia: A Case Report
ABSTRACT Embryonal paratesticular rhabdomyosarcoma can mimic benign inguinoscrotal conditions such as inguinal hernia. In children with persistent, painless scrotal masses, early cross‐sectional imaging and prompt radical inguinal orchiectomy with histopathological confirmation are essential.

Experimental study on cogging-torque reduction of transverse-flux motor with skewed armature cores
Transverse-flux motors are suitable for getting high torque density by increasing their number of poles owing to the independent coil design from the number of poles.

A Study on Core Skew Considering Manufacturability of Double-Layer Spoke-Type PMSM
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
