A Non - Conventional Type of Permanent Magnet Bearing
By using staggering magnets, we obtain a particular type of magneting bearings, owning very interesting properties : plane gap, null axial force, and absence of coupling produced by magnetization non-homogeneities. These bearings are well adapted for low rotational speed systems, and for partially-magnetic suspensions.
متن کاملThrust Force Ripple Reduction of Two C-Core Linear Flux-Switching Permanent Magnet Machines of High Thrust Force Capability
Linear flux-switching permanent magnetic (LFSPM) machines are good choices for long stroke applications. These machines deliver high thrust force density in addition to the machine structure where permanent magnetics (PMs) and windings are all on the short mover. For LFSPM machines, their performance is always affected by big thrust force ripple. In this paper, for two C-core LFSPM machines of ...
متن کاملThe Analysis of Ironless Moving-Permanent-Magnet Synchronous Linear Motor Thrust Fluctuation
Wherein, the thrust fluctuation is an important factor affecting the positioning accuracy of the workpiece table. Many scholars have studied the thrust fluctuation reduction methods to improve the motor performance. Some articles optimized structure size [1], or the analytical method ignoring the end effect [2], or using look-up tables [3]. Another scholars have adopted active control strategy ...
متن کاملRecent Theoretical and Experimental Results
We consider a wireless ad hoc network with single antenna nodes under a two-hop relay traffic pattern. Some of the nodes in the network form source/destination pairs, while the other nodes serve as amplify and forward relays. The relay gains are assigned such, that the interference between different source/destination links is nulled (multiuser zero forcing relaying; MU-ZFR). This essentially r...
متن کاملBrushless Permanent Magnet Servomotors
Electrical motors drive a variety of loads in today’s world. Almost every industrial process relies on some kind of electrical motors and generators. There exist billions electric motors used in different applications all over the world. Majority of them are small fractional HP motors use in household appliances. However, they used about 5% of the electricity used by the motors. Three phase mot...
