“…The inductance (L min ,L max ) calculation methods of tubular linear reluctance motors was described in [15]. According to Equation (12), it is clear that the inductance (L) is a function of plunger position, but it must be mentioned that its magnitude is dependent on the value of maximum inductance.…”

SUMMARYLength difference between plunger and winding is one of the most important issues in Tubular Linear Reluctance Motor (TLRM) design. Determining appropriate plunger length can have effect on TLRM output parameters, i.e. plunger speed, magnetic force and efficiency. In this paper, dynamic models of TLRM in two different conditions, i.e. equal and unequal length, using electrical and mechanical equations are proposed. Afterwards, the dynamic models of two conditions are simulated. The comparison of simulation results would determine the appropriate plunger length. Finally, in order to validate the modeling results, simulation and experimental results are compared.

“…In the previous FEM analyze of the linear tubular stepping actuator, the first step of 2.54 mm will be studied when phase coil B is energized in order to calculate with the software Magnet from Infolytica Corporation, the tangential thrust force, the magnetic and the flux density versus the current and the displacement variation. With the FEM analyzing we can also calculate the inductance and the coil resistance [12].…”

In this paper proposes a Finite Element Methods analyzing applied to the linear tubular stepping actuator. The linear displacement is modeled by means of a layer of finite elements placed in the air gap. The design of the linear stepper motor for achieving a specific performance requires the choice of appropriate tooth geometry. The magnetic field of the actuator has been analyzed using the finite element method over a current-displacement variation. The magneto static field and electromagnetic force was introduced in order to predict before construction, the inductance values according to the displacement and the currents into the coils. The results were obtained for the magnetic flux density distribution and the electromagnetic force for different positions and current.

“…Their study focused on LSRM modelling neglecting end effect and assuming the inductance and force have a sinusoidal form. Ali Mosallanejad, Abbas Shoulaieet al derived an equation for change in inductance in a tubular linear reluctance motor during its operation for the linear movement of the plunger based on energy method in [2]. Field intensity inside the core is considered but the flux deviations or the flux leakages at the entry and exit ends were not considered.…”
