Jason McNeil Posted October 2, 2015 Share Posted October 2, 2015 An engineering friend took his KS 800W motor apart: he reports the stator is 6mm wider than your typical 14" eWheel & the impedance of the copper windings is significantly lower—probably on account of larger gauge wiring, higher quality copper, or both.

dmethvin Posted October 2, 2015 Share Posted October 2, 2015 Why did he take it apart? Does it have a problem?Well if it didn't, it does now!An engineering friend took his KS 800W motor apart: he reports the stator is 6mm wider than your typical 14" eWheel & the impedance of the copper windings is significantly lower—probably on account of larger gauge wiring, higher quality copper, or both.Interesting. So does it consume more power at normal cruising speeds due to that or does the controller simply reduce the pulse width to even things out? That's the one thing that's always concerned me about the higher-wattage motors, whether they will reduce average battery life. Link to comment Share on other sites More sharing options...

Gimlet Posted October 3, 2015 Share Posted October 3, 2015 As impedance leads to wasted energy in the form of heat the savings of low impedance should help a lot. Link to comment Share on other sites More sharing options...
