Building a Custom Dynamometer

Abstract PDF: 

Blendtec has made a name for itself by selling professional grade and home use blenders. In their endeavors for continual improvement, Blendtec has found a need to test the capabilities of both their blender motors and the corresponding software. Blendtec would also like to make sure that motors for future products and innovations live up to the strict performance standards that their customers have come to expect.
Dynoblend was tasked to construct a dynamometer that would both accurately and precisely capture the torque and RPM outputs of current and future motors. One of the main constraints of this project was the need for a dynamometer that would not only provide torque in a stalled condition, but also reach speeds in excess of 30,000 RPM. Dynoblend’s solution includes the purchase of a hysteresis brake which is rated up to 35,000 RPM. A custom work station was created that would allow all of Blendtec’s blender housing units to attach directly to the dynamometer without modification. Using LabVIEW as the platform, Dynoblend created a program capable of controlling the inputs to the dynamometer and recording the speed/torque outputs in graphical form.
Dynoblend was able to not only provide an invaluable tool but at a fraction of the cost. The finished product exceeds Blendtec’s RPM, torque, and accuracy requirements all while being tailor-made to test their blenders. The customized software, created by Dynoblend, will allow Blendtec to test, analyze, and compare results real time as well as store that information for future retrieval.
