In this course project, I designed and built a hand-held mixer with a strict $25 budget and a compact motor. The final design spins the whisk at 1120 RPM. Power is transmitted through a simple system: a gearbox mounted to the motor and a belt drive that transfers motion from the motor shaft to the main whisk shaft.
The figure above shows the basic power and torque curves for the motor used. I tuned the motor’s gearbox to favor relatively low torque and high RPM, optimizing the mixer for efficiently whipping liquids. The image below shows the final product, which successfully whipped approximately one cup of cream during a live demonstration.
