“…Magnetic hysteresis models are often used to predict the iron losses due to magnetic hysteresis [2]- [7] in, e.g., toroidal samples or laminated strips. However, experiments are rarely performed on reluctance actuators [8], [9]. In [8], the inverse classical Preisach model (CPM) is used for actuator control, but no eddy currents are taken into account.…”

Magnetic hysteresis in the force of a prebiased E-core reluctance actuator is researched using three analysis methods. Simulations are performed with a 2-D/3-D finite-element method (FEM); and two semianalytic methods are evaluated, namely, a generalization of the classical Preisach model, which is combined with a dynamic magnetic equivalent circuit (MEC) method, and a complex impedance model, which is combined with a static MEC model. Ultimately, the FEM simulations and analytic models are examined by a comparison with force measurements performed with a piezoelectric load cell. Index Terms-Finite-element method (FEM), magnetic hysteresis, Preisach model, reluctance actuator.

“…These effects can be reduced by using magnetic cores made of thin laminations of soft ferromagnetic materials. From the analysis in reference paper [4], the eddy current is not visible below kHz range with thin laminations of soft ferromagnetic material, and the main factor causing the force error is the hysteresis. When specification of the force predictability becomes very strict, the current air-gap force is no longer a single-valued function and hysteresis in soft ferromagnetic materials becomes dominant.…”

The next-generation fine stage of the wafer scanner needs a suitable actuator to meet the requirements of high speed, high acceleration, and high precision. The voice coil actuator is no longer the best choice because of its large size and the heat dissipation is difficult to solve. The reluctance actuator can provide a big force based on a unique property of small volume and low current, making it a very suitable candidate. But the strong nonlinearity such as the hysteresis between the current and force limits the reluctance actuator applications in nanometer positioning. This paper proposes a nonlinear current control configuration with hysteresis compensation using the adaptive multilayer neural network. Simulation results show that the hysteresis compensator is effective in overcoming the hysteresis and is promising in precision control applications.

“…Additional efforts have investigated the magnetic hysteresis effect on the force generation of reluctance actuators for high-precision applications. One-dimensional analyses can be found in [22,23], whereas 2D and 3D finite element (FE) approaches have been also proposed [24]. All of these works address the hysteresis phenomenon exclusively on soft magnetic materials.…”

Modeling and Validation of the Radial Force Capability of Bearingless Hysteresis Drives

The hysteresis motor technology combined with the magnetic suspension makes bearingless hysteresis drives very appealing for high-and ultra-high-speed applications. Such systems exploit the magnetic behavior of the rotor material to achieve mechanical torque, but the hysteresis can significantly influence the magnetic suspension performance. The literature so far has focused mainly on the motor investigation. On the bearing side, the design and the performance assessment have been carried out by neglecting the hysteresis phenomenon of the rotor material. In those cases, the hysteresis of the rotor material is negligible and hence it slightly affects the force generation. In a wider perspective, this paper intends to investigate the force capability of electromagnetic actuators based on materials of large magnetic hysteresis behavior. To this purpose, the proposed numerical model, based on the finite element method, accounts for the magnetic hysteresis. The experimental results confirm the validity of the modeling approach, thus providing a useful tool for the design as well as the investigation of such systems.
