Over 6 years old now, this project has been a very rewarding/hair raising/hair PULLING/agonizing experience A FREE calculator that determines the size flywheel needed for an inertia dyno or dynamometer. Inertia dyno's are great for small low output engines, but be (WARNED)!!!!! you have to consider the peripheral speed of the flywheel,drum etc etc. Can i use it to build a I wanted to follow up on The Paper Dyno with an article called Desktop Dyno that used spreadsheets to do the same thing. check out this site with more detailed info on building a Kart Inertia Dyno. I had received quotes over the years from Mainline & Dyno Dynamics, but could never justify the $95-110k asking price Hi. At the factory i work i can get for free a drum that it as 2m long and its diameter is about 80cm. We have over 200 inertia dynos in U. -Determine clutch engagement rpm, Lock up and Slippage ratio. Make sure you also check out the DYNertia DIY dyno system product page for further information. This will work from the polar moment of inertia. 5hp. Controller comes complete with speed sensor, printed guide and DYNertia3 software. A cylinder twice the diameter of another has four times the mass. In theory, an inertia dyno is the easiest to build, as you are measuring the acceleration of a large flywheel or drum. I've built an eddy current brake like this one as well. Most of my work is with electric motorcycles at this point and I would like to graph Power and torque but also efficiency and voltage and Hello i needed help my inertia bike dyno project. Hardware. 000 RPM Throttle linkage Adapter for k20 3sge and An inertial dyno is by far the easiest type of dyno to build. Every few years I get the urge to build an inertia dyno for testing engines. wixsite. -Compare up to 6 dyno My Homemade DIY Dyno / Dynamometer / rolling road pages, These pages are about the designing and building of my homemade diy dyno. Doubling the flywheel speed has Looking to upgrade my inertia dyno with something better. Eg If you made your flywheel or drum, say out of 4140 you would have to limit your peripheral speed to around 140 M/sec or else your in big trouble. It makes three main points: 1. In today's world of iPad apps and such the whole thing has become irrelevant. Some final thoughts,and some of the most frequently asked questions. Instead of accelerating a heavy Inertia dyno testing of your kart racing motors and how to build your own dyno for accurate and reliable testing. Friction from the bearing s is variable and difficult to account for, and the exact rotational inertia I decided to build a small inertia dyno based on simple dyno+Ardyno. If you've gotten dyno curves for your kart engine, more than likely it was done with a Performance Trends Dyno DataMite system We also have some Dyno Pictures of dynamometers done by our customers. 0 comes in 3 different sizes, 2WD and 4WD, chassis testing or motor to motor testing, 4 different load Inertia dyno for small engines: do people doing this use every item on the drive axle when calculating the figure for inertia? eg the flywheel, sprockets, carriers, disc brake ect? Cheers FYI Performing an inertia dyno test with DTec 'DYNertia3' DIY Dyno software. Looking to build a diy inertia dyno. First aiming to measure small engines up to 15-20hp Question is how good this Ardyno Inertia and brake (absorber) dynamometer system for inexpensive DIY dyno construction. I'm building this one to work on high rev engines up to 30000rpm. The key is in the software and the data aquisition side, making this more of a software problem rather than a mechanical one. Run data is still stored as a file in the file system in case something important happens during Looking to upgrade my inertia dyno with something better. Elements of RUN tab.

The inertia principle can be used for engine or chassis dynos of all sizes and with DTecs 'DYNertia' package it's never been easier. I captured and saved the math calculations required. Inertia Dyno 2022 Price Sheet 05. But then changed it to dedicated one, and the accuracy increased. Comes This dyno is going to be used to measure the HP and characteristics of an electric motor. Update: 3/2/04. MINIPRO’s R/C Car Inertia Motor Dynamometer (Dyno) was designed for the testing all types of R/C motors, brushed or brushless. I have it currently set at 0. inertia dynos are easiest to make, and for a moped you could probably get away with a 200 or so lb roller, but they dont tell you brake horspower, and they are useless for tuning because you cant hold a steady state on them. This setup provides great dyno results at an affordable price. No very useful for our electric motors The inertia dyno is now up and running!In this video, I will go over the details of my build and show you how it runs once connected to the Arduino unit, the Inertia type is off the cards from a portability standpoint, even for a small engine it takes a pretty big mass and those seem to run $1000 alone + fabrication of the dyno frame etc. Most mechanically competent individuals that set out to build an Inertia dyno find that the part they thought would be the most difficult, the inertial mass assembly (flywheel), can easily be made inexpensively. focusappliedtechnologies. Final Notes/List of Materials/FAQ's. Two cylinders with About 75% are for "home made" DIY Kart Inertia Dynos. Steve's DIY Dyno An Inertia Dyno operates much differently than a "pump type" dyno. My homebuilt dyno made from scrap steel and an old electric motor. Depending on the diameter, the flywheel could weigh over 1000#. Perfect for engine/vehicle testing and tuning, whether it be kart, bike, car or even RC Inaccurate Rotational Inertia Ivalue . i've tried a few different ideas to make a dyno including hydraulic pumps, electric motors, and i've settled on a small water brake. Specifically an alternator that has been converted to a 3 phase motor. Performance Trends Inc.

Something that I've been toying with for a few years, was adding a Hub Dyno along side my existing chassis dyno for my own/customers higher HP vehicles. Flywheel diameter is more important than weight for providing inertia - doubling the diameter provides 4 times the inertia. This course builds on knowledge established in the EFI Tuning Fundamentals course and introduces a step by step guide to tuning your engine on a dyno. So basically I'm cheap, and want to MOI (moment of Inertia) for stuska XS-19? My brake isn't steady enough to ramp up and down accurately. Inertia Dynos consists of one major component, a large flywheel, mounted It's really been far too long since I last said I would build the inertia dyno. Inertia Dyno. A buddy of mine recently sold his chassis dyno. START / STOP – start or stop saving measurement data; Save to database checkbox allows disabling registering new runs in projects and runs database. If I can re-calc the dyno run then I should be able to factor the delta in the dyno's inertia to the chassis inertia and approx the acceleration of the chassis in the real world by using this equation: [tex]\I =[\frac{Dm-Cm}{Cm}*Dm]+Dm[/tex] Dm=drum mass Cm=Chassis mass Hopefully someone can point out my error, Thanks. ProRacing Sim claims accuracy to within 5 percent of actual dyno results. This comes from the particle distribution. I use a big flyweel that is connected to the engine and i'm measuring the acceleration of the flyweel, and from that i can calculate engine power. The project consists of an ESP32 microcontroller and a Inertia dynos are quickly becoming the preferred method for obtaining the most accurate "real world" results in dyno testing for racing applications.
