SimLab Tutorial Summary: 2D SPM Motor Brushless

Description

This tutorial shows how to use SimLab to design and run electromagnetic analysis with Flux solver for electric motors. The studied device, a brushless DC motor with surface permanent magnet, includes the following elements:

• a fixed part (stator) including yoke, slots, and windings
• an air gap
• a movable part (rotor) with surfaced magnets

In this tutorial, three typical transient magnetic analyses are defined to evaluate the motor performance:

• Analysis 1: Computation of the cogging torque
• Analysis 2: Back Electromotive Force
• Analysis 3: Constant speed

Note: The geometry model is built by the Sketch of SimLab

Analysis 1: Computation of the cogging torque

Analysis 2: Back Electromotive Force

Analysis 3: Constant speed
