Im looking at making a diy torque sensor, low power (5-700w peak), light weight mid drive. I currently have a tsdz2 which I like very much, except the ground clearance. I do have a MY1018 brushed motor laying around here, a BB torque with a freewheel on the way, and a CA v3. Trying to make a lightweight system I will also use a small battery as possible for what I need, and I am a little sceptical about how efficient the brushed MY1018 motor is. Last time I used it I only had a cadence based system, so its not a direct comparison, but it used almost twice the energy as the tsdz2 on the same routes. The MY1018 ticks all the other boxes with size, gearing and power. I have tried finding a comparable brushless motor, but cant seem to find anything. They are either way too big (cyclone, etc), or small without reduction gears (RC motors), and thus way too high rpm. Are there any brushless motors in the 500-1000w area with planetary gears that would be suitable for a mid drive build?
