I really need to know the maximum Rpms of the motor to know the peak power. I have seen some companies say their motor has 800 watts but they don't tell me the rpms. I don't even have to try and test out the electric skateboard to see if the torque is powerful enough for my weight if I know the highest rpm speed it has. The most torque is when the rmps are at the lowest, kinda like a car in 1st gear.
Horsepower of the motor is come up with by knowing the rpm and torque. With an engine for example, the torque and Horsepower are the same when the rpms are at exactly 5250.
The bigger the motor the more energy it eats up from the battery as its takes more energy to move a bigger mass than a smaller mass motor. A 200 watt Pipemaster, for example, has a very small motor but is geared to go 22 mph and lasts 20 miles but has a bunk torque compared to the 800 watt motors. Note, they all go the same speed but the 200 watt takes more seconds to get up to speed.
The big G force you feel on some skateboards is at 1000 rpms on some and on the 1500 peak watt models, you feel it right at the first split second the motor starts spinning and you don't have to wait that 1 to 2 seconds for the highest torque to kick in. With the more powerful motors the maximum torque kicks in closer to 0 rpm's. The lighter a person is the closer to the lowest rpm it is. So, a heavy person takes a little longer to accelerate and overcome a stationary position. If a board is rating for 0 to 20 in 5 seconds, this can be tested without the heaviest person being on it. I alwasy ask if the acceleration rating is based on which weight. The one thing that is very unclear until I finally tested them myself is the acceleration time under loads. Different loads don't always give that 5 seconds. I will say that the E-glide and Gnar board specs are based on the heaviest load rating for their board which I wish all companies did.
By knowing the rpms, it helps me determine the quality of the motor as long as I know the constant wattage, voltage, and amperage. A lot of companies don't even know their rpm speed. But knowing the other variables is helpful enough if you understand how they all relate to each other. This can make the difference between a high end motor and a motor that is a fraction of that cost.
