NSD Spinner Torque Specifications

HOW MUCH RESISTANCE DOES THE SPINNER GENERATE, REALLY?

The rotor in your NSD Spinner is capable of sustaining very high speed, and as with most spinning mass, will require torque applied to maintain that spinning speed. We have tested each of our Spinner models to provide the actual torque generated at 10,000 RPM. The chart below shows you the model number, the torque at 10,000 RPM, and the equivalent to twisting a dumbbell weight in your hand (keep in mind, torque can only be equated to a twisting force*)

Some of our competitors may show you that the product can generate "up to xx lbs of torque," while the statement may factually be true, they've left out some very important and basic information that does not show you the whole picture. If you've ever used a gyroscopic wrist and arm exerciser similar to our Spinner, you'll quickly realize that no matter what speed, the small ball does not magically feel like it weighs more than a dumbbell nor does it require "30 lbs" of force to overcome the resistance. For example, the "Essential" line up of PB-188 series Spinners will generate 26.8 ft-in of torque at 10,000 RPM as confirmed on our dyno-tester, and since the radius of the gyroscopic rotor is approximately 3/4", you can sort of infer that the PB-188 series can make as much as "36 lbs" of force at speed. But in reality, the force it takes to keep the Spinner spinning at 10,000 RPM is closer to trying to twist a 9 lbs dumbbell in your hand, assuming the dumbbell is approxmiately 6" in length with the majority of the weight on the end. While that force may not be significant, it's the rapid, repeated movement that makes working out with the Spinner more effective at targeting specific muscle groups in your arms.

We hope this page will give you a better understanding of the actual torque specifications of our products and help you choose the right Spinner to compliment your exercise.

The numbers provided above indicates the equivalency to a twisting motion with dumbbell, as measured at 10,000RPM. At higher speed, the Spinner's rotor will provide MORE resistance proportionally. Also, if you follow some of the exercises outlined by Jonathan on Jonathan's Corner, some of the exercises that requires a wider range of motion will result in a higher multiplication factor at higher RPMs.
