3D Actuator Design and Optimization

Nowadays, most devices involve a few simulation steps from pre-design to final validation. Engineers have to try many configurations, define working conditions and make sure the device will run trouble-free and optimally. Flux software can help designers to perform their studies at every step of this industrial process.

The presented example is a 3D actuator with a magnetic circuit and a mobile part. It is supplied by a coil with a maximum number of turns depending on the wire diameter. This wire diameter choice will affect the size of the coil, but also the force on the mobile part. The force increases with the number of ampere turns so it will be a compromise of the losses and the force obtained with this coil. The bigger the wire, the lesser the losses, but the lesser the force will be too. Concerning the materials, both frame and mobile parts use conventional iron material from Flux using a spline for B(H) curve. The coil is made of copper with constant resistivity. This actuator is an example of a small contactor switching between two positions.

The following article presents an example of an actuator as an illustration of how to pre-design a device, how to optimize it with multiple objectives and how to run the final validation before releasing the final product. All of these steps are possible using the 3D modeler, the parametric study, GOT-It optimizer and all the simplification tools.
