When a product is sold, electromechanical, mecahnical, electronic or otherwise normally the manufacturer supplies physical data, maximum allowable voltage and current. In this case, driver limits as well as connection configuration. Go look up an off the shelf motor and you will see all of the...

Actually it is a Bafang BBSHD 1000W, As I understand it, the other versions have an external driver card. I have an internal driver circuit driven with a 58.8 volt battery pack. Many of my questions would be answered if I could reverse engineer the driver card. I read where people continue to...

The e-bike that I purchased came with no instructions for anything. I finally found a manual for the C965 display with 5 button controller. The manual does not seem to be written for this display since I cannot change the functions as the manual outlines. That is a problem but now that I see...

Again, the coolest drivers soild be close to a square wave, excluding rise and fall times.. The driver will be putting out all voltage or all curent so no wattage. Can't be done in a real world. I wasbnuncer the impession tha a sine unverter was best for house wiring.

I have always been under the impression that a fast switching square wave driver would dramatically kkeep the mosfet heating lower. The fets are either full on with very little voltage drop and high current or full off with high voltage but very little current through the fet. As I understand...
