Easily calculate and compare different motos in terms of stator volume and surface area!
This stator volume calculator is a greatly expanded version of the smaller calculator on the Tools page. It comes with a better UX for adding comparisons, sort options, and an API-style URL that you can use to share comparisons with others!
Calculating the stator volume is important when you want to compare motors of different sizes. Two motors
with seemingly completely different sizes can have very similar stator volumes, and so you can expect
similar performance. This applies for most of commonly used sizes until you move to very large motors.
The stator surface area is also important, the more surface area you have exposed to the air, the more heat you can dissipate.
The motor stator size is listed as
xxyy, with the
xx being the
yy being the height. A 2207 motor will have a stator 22mm wide,
and 7mm high
The calculation to get the stator volume is for a simple cylinder:
π × r2 × h
And the calculation for the surface area is:
(2 × π × r × h) + (2 × π × r2)
