Hey Ken, as with all cases of the same motor option with just a different winding, if you are going up a hill where both motors are running the controller at the current limit, then you will get a marginal amount more torque from the slower motor due to 2nd order effect. This is exacerbated a bit by the fact that the HT3525 has a slightly higher copper fill factor than the HS3540 (63 strands vs. 60 strands). However, if the hill is not steep enough to cause the controller in the low speed motor to run at its current limit, then the higher speed motor will do the climb faster hands down.itselectric wrote: Well, this very much the same thing with our local customers, cannot decided HT or HS. So, I am hoping to make another video comparison this coming weekend. A race up hill between HS3540 and HT3525. My assumption is the HT3525 should go up hill better then HS3540 due to early torque delivery from the motor. We will see...watch for coming video....
If the myth continues that the slower speed motor winding leads to a higher torque motor, then ARRG I will want to roll in a grave. Crystalyte is not doing the scene a favour by using a High Speed / High Torque naming convention. It should be HS/LS for high speed, low speed. Since speed is already implied by the last two digits (40 and 25 kph respectively), then it's redundant anyways and H3540 and H3525 would be better.
Then we just need to find something funny for the 'H' to stand for.
