A guy named Sam decok and his clang verbally attacked me on the ES Facebook page for explaining field weakening with similar info as stated above.
They wanted to know why a hub was not making anywhere near its no load speed and I said it needed more torque to reach its no load speed it could be achieved through not overvolting the motor in the first place, more amps or a rim reduction without rewinding etc.
But MR decok knew better and said field weakening was the way forward, its the way of getting the hot motor working at its limit to work even harder and slip further from its no load speed into the realms of melt down.
They were nice enough mind to call me a smackhead, said i should hand my qualifications back in engineering and his side kick said he would smash me face to face lmao shows their age and stupidity, little does he know to pick a fight size up your opponent first outside and in or you may end up on the floor in a position you have no control over what happens next, a well trained person has restrain and no need to prove what they know or how dangerous they are.
Left Facebook for good past 6 months and just use email and this forum with a bit of YouTube, keep my distance from being hassled.
