The application to simulate is a linear motor to be used in a future magnetic levitation railway. We publish this with kindly permission by HARDT GLOBAL MOBILITY.

*MAGNETICS for NX/Simcenter* is specialist in simulation of electric motors. The examples in this chapter demonstrate synchron, asynchron or other motor types.

In this application case we perform a FEM analysis with parameteridentification and circuit simulation of a universal motor. The typical characteristics speed and current over torque are determined.

The aim of this analysis is to analyze the torque behavior of the rotating magnet of this Timex M901 motor. In particular, the angle of the locking points will be found and the associated holding torques.

Dynamic analyze for the induced voltages in the three phases of the coils over the rotor angle.

3D transient magnetodynamic Analysis of the current over the time based on the example of TEAM 24 Benchmark.

This example shows how a servomotor is analyzed using MAGNETICS and NX NASTRAN. The magnetic forces on 36 teeth are transferred to a structural (acoustic) solve, which gives answers to dominant noise frequency and pressure.

In this showroom example we perform a FEM analysis of a 3KW induction motor. The analysis is completely done in NX. No parameter identification and system simulation is necessary. The typical characteristics speed and current over torque are determined.

Transient nonlinear Torque Calculation of a 3D Solid Model shown on the example of the TEAM24 Benchmark model.

Calculation of the Motor Torque of a rotating 2D model shown on the example of a Siemens Servo Motor 1FT6.

In this case study a linear motor is designed and using a step by step enforced motion analysis the forces acting on the coils are determined. Read full article

The example shows how to determine and optimize the performance of a test induction (asynchronous) machine. Of particular interest is the method that is used for parameter identification: inductance and ohm resistors are calculated with FE. With these values, an analytical network statement is fed.

MAGNETICS for NX can calculate losses using different approaches e.g. eddy losses or losses based on the Generalized Steinmetz Equation.

This example demonstrates an asynchron motor. It is belonging to the group of test examples that are well documented. See in this description how induced voltages are computed and compared to the reference data.
