This article presents the process of building a hybrid analytical model (HAM) for surface-mounted permanent-magnet machines. The HAM couples reluctance network (RN) in stator region with magnetic scalar potential air gap and magnets regions. can deal slotting effect straight teeth, takes saturation into account iron material using RN model. It is calculated under open-circuit loaded conditions....

Some induction motors present saliencies that periodically modify the air-gap flux following a sinusoidal shape. Consequently, these modulations are reflected in transient leakage inductance. Therefore, inductance can be expressed as constant term or offset, which comes from symmetrical machine, plus all motor saliency sinusoids, modulated by mentioned saliencies. Since linked to rotor position...

In this project, the quad processing machine for cutting, shaping, grinding and drilling machines is kept to be in same attachment. This eliminates risk of material handling table. unit driven by 0.25 H.P. three phase motor 1440 rpm. linked with cast-iron (CI) slider. enables slide get rotation movement into reciprocating motion having a stroke length 75mm. The head slotting can tilted getting ...

Permanent magnet Vernier motors (PMVMs) possess the advantage of high torque density for high-performance applications. However, low power factor challenge makes it unacceptable direct-drive A lack accurate modeling method based on motor sizing law, i.e., air-gap flux density, linear current and geometry parameters, raises difficulties machine designers to further conduct research performance m...

In e-commerce fulfilment centres, storage assignment is critical to ensure short response times. To achieve this, many online retailers have moved product dispersion in combination with turnover-based slotting. However, commonly used policies do not fully utilise the historical customer demand information optimise assignment. This paper addresses a comprehensive approach estimate joint effects ...

Carbon nanotubes (CNTs) have been applied as nano-fillers to improve mechanical, thermal and electrical properties of polymers. Despite near net shape techniques could be used manufacture nanocomposites, micromachining processes are still necessary attain high surface quality dimensional accuracy. Besides, nanocomposites a potential approach produce micro-features/components, following the mini...
