Tabletop Dynamometer Stage 1
This project has been a long-time interest of mine, ever since becoming interested in PMSM motors for hobbyist purposes and using . Even though it is one of the most important parameters to design around, many manufacturers and retailers do not publish torque data for their motors. So, unless you are ordering from T-Motor, the best you can do as far as estimating the torque-speed curve is guestimating based off of the volume within the airgap and the torque constant (which is usually reliably given). That is unless you have your own dynamometer and access to the motor. Then you can just measure everything you need directly! Another purpose of dynamometers that I would like to have my own rig for is robotic actuator characterization - so testing the motor and the transmission together. Specifically, I am interested in low-ratio QDD transmissions paired with medium-sized brushless motors. This is low-speed territory, so...
