Induction Motor in 2D
Application ID: 14487
This is an example of a model of an induction motor in which the eddy currents are induced in the rotor by the time harmonic currents on the stator windings and the rotation of the rotor.
In this example, we analyze the induction motor in 2D using the transient solver in the Rotating Machinery, Magnetic interface. We also investigate the motor’s start-up dynamics by coupling the electromagnetic analysis with the rotor dynamics, including the inertial effects. Finally, we compare results from a benchmark model (TEAM workshop problem 30a) with those from the model.
The rotational torque and angular speed of the rotor when an alternating current is passed through the stator windings are calculated as a function of time. The effect of the step change in the load torque is also included in this model.
This model is featured and explained in much greater detail in the following blog post: How to Analyze an Induction Motor.
This model example illustrates applications of this type that would nominally be built using the following products:
however, additional products may be required to completely define and model it. Furthermore, this example may also be defined and modeled using components from the following product combinations:
The combination of COMSOL® products required to model your application depends on several factors and may include boundary conditions, material properties, physics interfaces, and part libraries. Particular functionality may be common to several products. To determine the right combination of products for your modeling needs, review the Specification Chart and make use of a free evaluation license.
