This article deals with the power-sharing control of bearingless multisector and multithree-phase permanent magnet machines. The proposed strategy allows to distribute power flows among three-phase inverters supplying machine during operation drive. technique is based on extension vector space decomposition modeling approach. components producing electromagnetic torque, i.e., <italic xmlns:mml=...

background and objectives: auto-induction is usually employed to achieve high cell density and overproduction of proteins with a simple and low-cost operation. the efficiency of heterologous protein expression in escherichia coli is determined by different parameters. interactions between these parameters usually complicate the identification of those that contribute more to the improvement of ...

normal 0 false false false en-us x-none ar-sa microsoftinternetexplorer4 background: the efficacy of mitoxantrone induction therapy in rapidly worsening multiple sclerosis (ms) is well established. plasma exchange is also applied as an adjuvant in exacerbations of relapsing ms. the aim of this study was to compare the efficacy of combination therapy with mitoxantrone and plasma exchange versus ...

in order to evaluate the different photoperiod and temperature sensitive pre-flowering phases in two cumin landraces a raciprocal transfer experiment from photoperiod 8 h to 16 h and vice versa under two different day/ night temperatures 20/10 and 30/20 ˚c was conducted. two model including ellis and adams were used to analyse the data and to quantify the duration of different developmental pha...

Under the condition of load changing, the magnetic field of traditional permanent magnet generators (PMG) is hard to be adjusted, and the mechanical bearings are significantly worn. To overcome the drawbacks above, a novel hybrid excitation bearingless permanent magnet generator (HEBPMG) is proposed in this paper, which has integrated the merits of hybrid excitation permanent magnet generators ...

It is important to clarify the eddy current losses in permanent magnet rotor for temperature rising to induce irreversible demagnetization when the bearingless permanent magnet synchronous motor (BPMSM) is operating at high speed. In this paper, the torque and radial suspension force producing mechanisms of BPMSM are introduced. The relative motion relationships among radial suspension force, r...
