FINEMotor™

Magnet System & Voice Coil Design Program

fine-motor

The FINEMotor program contains 36000 FEA simulations and is the ultimate tool for prediction of SPL & T/S parameters including BL(x) and Xmax with complete winding data.

FINEMotor is the optimum simulation tool for designing the magnet system, voice coil and spider for woofers, domes, telephone-receivers, headphones etc. This includes Rectangular Micro Speakers and Voice.

Precise and Fast
When SEAS was designing a new product line and used FINEMotor for the first time, the result was right on target and saved them a lot of time. After this first attempt SEAS now works with FINEMotor for all new motor systems.

Intuitive
You don’t need to know a lot about drivers to be able to use FINEMotor. This is a tool not only for engineers, but also for technicians.

Material database
With the latest version of FINEMotor you can add your own magnets and wires to the database, which already has a lot of standard Chinese materials to choose from.
