This paper deals with a methodology developed for fast and accurate dynamic modeling of Hybrid Stepper motors. The proposed method is based on réluctance network magnetostatic modelling validated by finite element simulations.
A 2D scanning micro mirror is modelled based on numerical simulations and optimized using the Matlab optimization Toolbox. The simulation model covers structural, fluidic and electrostatic effects. The goals of the optimization are low driving voltages and robustness against process variations. The simulated behaviour of the optimized design is compared to experimental results.
This paper studies the effects of iron losses on the magnetic field solution and evaluates their impacts on the overall performance of electrical machines. Because of the complications associated with the inclusion of iron losses into the magnetic field solution, the losses are usually omitted from the finite-element (FE) analysis while they are estimated in a post-processing stage. We conducted a...
In this paper, inductance of an in-wheel switched reluctance motor (SRM) would be computed by using the MEGA software. MEGA, a computer simulation program that model the electromagnetic devices, solves the low frequency subset of Maxwell's equations using finite element method (FEM). Magnetic field strength would be computed in accordance with the SRM specifications. With different values of current...
This paper presents the performance analysis of a three-phase three-stack permanent magnet (PM) claw pole motor by using an improved phase variable model, which has been developed for accurate and efficient performance simulation of PM brushless DC motors. The improved model can take into account the effect of magnetic saturation and rotor position dependence of key parameters including back electromagnetic...
Saturation effects in salient pole synchronous machines are generally modelled by assuming that the saturation effect is primarily limited to the field pole. However, saturation of the stator teeth and core can also become saturated such as when operating as a generator with a leading power factor load. This paper addresses the modeling and simulation of simultaneous saturation of both the stator...
Recently both d-q and instantaneous symmetrical components (i.s.c.) models for faulty cage induction machines have been proposed for numerical simulations of stator instantaneous currents. Applying FFT algorithm to stator current the sideband components at frequencies (1-2s)f can be evaluated. The amplitudes of these components are commonly used as diagnostic index to assess rotor condition in the...
