That’s a good data point. It can lead to a restoration of confidence, supposing there’s a good explanation.
The devil’s in the details when it comes to high-power, high-efficiency motors. Heat is a huge killer, and a few percentage points of efficiency can represent thousands of watts of waste heat. That’s the difference between full power for 180s and full power for only 30s, which itself is the difference between being high enough off the ground for safety and, well, not.
Thermal issues arising from motor losses can lead to having to spend tens of thousands of dollars, or even a failed project (ask me how I know). So it’s not a non-trivial hand-wavey thing for them to get wrong.
There are many ways to have arrived at the wrong numbers, however all the published values are off by basically the same margin. This points away from miscalibrated test equipment and toward someone consciously manipulating numbers, possibly by using measured test data to calculate the rest. So maybe they got RPM, Voltage, and Current-- all very easy to measure-- and backed out torque from that.
And this is such a terrible mistake it’s hard not to argue that it burns a reputation for forever. This isn’t their only webpage where this is happening. You don’t publish fraudulent-- or even overly optimistic-- numbers when you’re at this cost and power level. These things aren’t toys, these are part of safety critical systems. People can get really badly hurt or development projects can be sunk. In the best of cases, you buy the motor and you wind up being burned and disappointed (like @ITGlider).
Not saying they deserve to fail as a company, but I would say that without an incredibly good explanation (careless intern, fired employee, previous management, etc…) that I could never trust them in the future. Otherwise, you’re left wondering what else they didn’t come clean on. Bearing life? Bolt strength? Demagnetization temperature? Winding insulation thickness, consistency, and melting point? All those things are not academic when it’s our silly butts on the line (and hopefully not on fire)!
