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
