Magnet System & Voice Coil Design Program
The FINEMotor program is based on 18000 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 also the optimum simulation tool for designing the magnet system, voice coil and spider for woofers, domes, telephone-receivers, headphones etc.
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.
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.
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.
