SimLab Tutorial Summary: 3D Electric Motor of Tesla Model 3

Description

This tutorial shows how to use SimLab to design and run electromagnetic analysis with Flux solver for electric motors. The 3D studied device, the Tesla Model 3's electric motor, includes the following elements:

• a fixed part (stator) including yoke, slots, and windings

• an air gap

• a movable part (rotor) with surfaced magnets



In SimLab, the 3D magnetostatic solution can be easily set up through the Quick EM Workflow.

Analysis 1: Computation of the cogging torque

The cogging torque is computed with a multi-position simulation and zero current value. The multi-position is simulated with a transient application at constant speed. The simulation step is set as 0.16666 deg and up to 6.66664 deg, which corresponds to 1 mechanical degree per second...

Analysis 2: Multi-static study

In this study, the rotor takes different static positions (from 0 to 90 deg). And the winding bodies (including end-winding parts) are taken into account with a defined current value. This study provides a quick performance evaluation of this motor.
