In the process of Doing the Math as part of a journey towards crafting me own mobility, the progress became impeded by the void of simple tools to aid in seemingly simple calculations. Therefore I am resolved to fill that space as time allows with (hopefully) useful wizards and calculators. The first offering is called:

The Archimedes-Winding Calculator

**Description:**

Given a

**length**and

**diameter**of wire, this application will plot out an Archimedes Spiral and return the number of

*Turns*and the resulting

*OD*. Two additional parameters are optional:

*ID*and

*AirGap*between the windings. These can be remitted in mm, meters, inches, and feet.

**Support:**

This

*Silverlight*application executes from a webpage, or it can be installed onto your desktop; it lives in the "sandbox" and is quite benign.

**Please PM me**if it misbehaves and I shall work up an FAQ

**Example of Use:**

If you know the

*flux density*of the potential motor then itÃ¢â‚¬â„¢s possible to calculated the length and size of the conductor required to achieve a particular output. If you know the inside perimeter of your potential winding you can math-out a simple circle by the following equation:

- Perimeter = Circumference (C) = 2 r Ãâ‚¬ -> C/ Ãâ‚¬ = 2r = ID (theoretical)

*Length*,

*Diameter*, and

*ID*it is possible to quickly determine the number of

*Turns*and the resulting

*OD*in one step, rather than with running a series of calculations.

**Target Audience:**

The application is perfect for

*Coreless*Motor designers and students of general electromotive understanding. The calculator would not meet the expectations for Iron Core stators as they require more complex modeling.

**Why Built It?**

Because the other calculators that I found gave me Length

*after*I estimated the ID and OD of the winding, or I had to provide ID and number of Turns, or with ID and OD, the Turns could be calculated based on the wire cross-section. In short Ã¢â‚¬â€œ I found the approach of the resolution to be a little hokey and inaccurate.

**WhatÃ¢â‚¬â„¢s Next?**

I am keen to get 3-Dimensional with the winding calculations in the next version and include other factors to better gauge heat and current effects. Other wizards and calculators are possible. I will announce releases here on this thread.

Enjoy,
