The parallel permanent magnetic suspension system using flux-path control is composed of a servo motor, radially magnetized disk magnet, and pair magnetizers. Establishing an accurate mathematical model difficult owing to the system's special structure nonlinear characteristics. To ac quire model, autoregressive exogenous (ARX) identification method applied system. First, input output data are acquired from experiment. Then, ARX established utilizing method. Lastly, relevant simulations...
An analytical method was proposed for obtaining the magnetic field distribution surface-mounted permanent magnet machines with structure of unequal poles. Firstly, Laplace equation and Poisson were solved using separation variables, then mathematical model motor poles obtained. Secondly, according to design parameters two types prototypes motors, flux density in air gap region motors calculated, respectively. Thirdly, by comparing results calculated obtained finite element method, this paper...
Accurate calculation of the natural frequencies permanent magnet synchronous motors (PMSMs) is essential to prediction vibration and noise PMSMs. The analytical numerical methods are respectively used calculate stator yoke, core, core with windings, motor casing system. It found that relative errors between calculated results traditional formulas very large. For sake reducing errors, novel calculating circumferential modal system proposed. Compared experimental analysis, effectiveness verified.
he establishment of the analytical model rotor eccentric surface-mounted permanent magnet syn-chronous motor (SPMSM) with unequal magnetic poles structure will be beneficial to calculating field andstudying noise characteristics quickly. Based on equivalent surface current (ESC) method and boundarymethod, SPMSM is proposed. Duringthe modeling process, produced by a (PM) obtained using ESC method, andthe effect air gap field, which arised from stator, replaced concentric sheet (CCS)magnetic...
Among the rehabilitation therapies for patients with stroke or paralysis, robot-assisted is a research hotspot now. However, there are not many cases of clinical application, mainly because complex structure, single function, high cost. This proposes new type 3-DOF (degrees freedom) upper limb robot in series structure an end-effector, which has 2 degrees freedom horizontal rotation and 1 degree vertical movement. It compact saves space, easy to be moved can realize training...
