• A sicp reinforced al - cu alloy and al matrix composites are fabricated by a new method - electromagnetic centrifugal casting , the effects of rotational rate for centrifugation , magnetic density , particle size and matrix on the distribution of particles and microstructure of matrix are studied
• The particle - enriched zone moves outwards as the rotational rate increases . by employing steady dc magnetic field to the conventional centrifugal casting method , the distribution of particles is changed . the most uniform distribution is obtained when the magnetic density is 0 . 15t
• The controllers have considered all sorts of imperceptible factors affecting the servo performances in a lpmsm servo system , which include the parametric uncertainties brought by the changes of the mobile mass , frictional coefficient , the thrust fluctuations aroused by the varieties of the magnetic density distributions and the time harmonic . the h state feedback controller restrains disturbances and uncertainties to keep the robust and stable performance . the ip controller , which has the ability of rapid response , is applied to satisfy the rapid performance
• According to the theory of electromagnetic fields , the large salient synchronous generator with fractional stator slot are calculated and analyzed by the finite element method ( fem ) in this paper . the fourier analysis method is applied to decompose the air gap magnetic density into the basic spatial component and a series of harmonic components and wave shape eigen coefficient of air gap magnetic field are calculated
• Due to 12 / 8 poles doubly salient permanent magnet motor , planar finite element method ( fea ) is applied to analyze the magnetic field inside the motor . and a series of static characteristics are investigated , such as field distribution , air gap magnetic density , field flux , inductance , static torque
• This program can be used to calculate continuous enclosure type isolated - phase bus of different volt and current conveniently . secondly , it calculates a series of rational continuous enclosure type isolated - phase bus for the external diameter of the enclosure is 900mm , analyzes and calculates the magnetic fields of the continuous enclosure type isolated - phase bus by using limited unit method . from this it acquires the distributions of magnetic fields and magnetic density as well as the eddy current
