FINEMOTOR PRO

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. Shorting Rings are simulated and designed in FINEMotor PRO.

FINEMotor has become the “Industry Standard” and  is the optimum simulation tool for designing the magnet system, voice coil and spider for woofers, domes, telephone-receivers, headphones etc. This includes Rectangular Voice Coils for (Micro) Speakers. 

FINEMotor is now offered in 2 versions, both containing 36000 FEA calculations: A Standard and a Pro version. The Pro version has all the features, advanced calculations including oval and square magnetic systems that are most commonly used in the design of micro speakers.

With the less expensive Standard version, you still have the opportunity to design all round motors including BLx curves, pole geometry, Multi-layer round/edge wire VC’s and Neo motors.

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.

Features
Designs Woofers, Midranges, Tweeters, Headphone drivers, Micro Speakers etc.
Accurate Prediction of SPL, T/S parameters and winding data.
