### Electric Motors In this chapter some available solutions of the MAGNETICS for NX/Simcenter Solver are presented as articles.

# Linear Motor for Magnetic Levitation Railway 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.

# Universal AC/DC Motor Analysis In this application case we perform a FEM analysis with parameter identification and circuit simulation of a universal motor. The typical characteristics speed and current over torque are determined.

# Cogging Torque on a Lavet Stepping Motor 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.

# Analysis of induced Voltage on a Servo Motor Dynamic analyze for the induced voltages in the three phases of the coils over the rotor angle.

# Transient Current after Switching Team24 Example 3D transient magneto-dynamic Analysis of the current over time based on the example of TEAM 24 Benchmark.

# Motor Analysis for NVH 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,

# 3KW Induction Motor FEM Analysis In this showroom example we perform a FEM analysis of a 3KW induction motor.

# Transient Torque Analysis on Team24 Example Transient nonlinear Torque Calculation of a 3D Solid Model shown on the example of the TEAM 24  Benchmark model.

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

# Linear Shaft Motor Design 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.

# Induction Motor Parameter Identification The example shows how to determine and optimize the performance of a test induction (asynchronous) machine. 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.
