    How much torque though? HP is nice but power is in the torque as much if not more than the voltage(HP)

    Lol:

    The new YASA axial flux motor weighs just 28 pounds, or about the same as a small dog.

    However, it delivers a jaw-dropping 750 kilowatts of power, which is the equivalent of 1,005 horsepower.

    I feel like we’d need peak horsepower output of a small dog to truly understand this.

      A dog’s power output comes from its muscle mass, which for a healthy dog is about 45% of its total body weight. This gives our 28-pound dog roughly 12.57 lbs (or 5.7 kg) of muscle.

      Studies of animal muscle show that the peak power output of vertebrate muscle tissue during a short, explosive burst (like a jump or the start of a sprint) is around 100 to 200 watts per kilogram of muscle.

      Now we can estimate the dog’s peak power:

      • Low estimate: 5.7 kg of muscle x 100 W/kg = 570 watts
      • High estimate: 5.7 kg of muscle x 200 W/kg = 1140 watts

      Converting these figures to horsepower (1 horsepower = 746 watts):

      • Low estimate: 570 W / 746 ≈ 0.76 horsepower
      • High estimate: 1140 W / 746 ≈ 1.5 horsepower

      So, a small 28-pound dog might be able to generate a peak power of around 0.75 to 1.5 horsepower for a very brief moment.

      So this YASA motor is somewhere between 670 and 1,340 times more powerful than the dog it’s being compared to in weight. That’s some jaw-dropping power output.

            Stop burning the planet down to generate social media comments

            I mean, I thought it would be obvious my issue was with using AI to do so…

            Even if it had been a serious question.

            But, to be fair I was thinking of what a normal.person would be able to parse, and not people who’s critical thinking had already atrophied from offloading to AI.

            They probably don’t have any idea what I meant and would need it explicitly spelled out.

              I didn’t realize it even was ai generated. but even if it is, that’s still a fairly off-putting way to respond.

                No you’re right…

                It’s not like it’s literally burning our planet down and the people profiting off it aren’t tech bro fascists…
