Muhammad Rodwan, 56, has been jailed for 16 years with a further three years on extended licence for a "brutal and shocking" machete attack on PC Stuart Outten.
Muhammad Rodwan, from Luton, slashed PC Stuart Outten, 29, after he was pulled over in Leyton, east London, in August.
Jailing him for 16 years, Mrs Justice Carr said "arrogant" Rodwan had shown "not a shred of remorse or insight".
A jury deliberated for seven hours to clear Rodwan of all attempted murder, but found him guilty of injury with intent to inflict serious bodily harm on him.
Muhammad Rodwan, 56, left PC Stuart Outten with horrific injuries when he launched his potentially deadly assault in August past year, only stopping when he was Tasered twice.
Sentencing, Mrs Justice Carr told him: 'This was a brutal and shocking attack with a machete on a police officer carrying out his duties during what should have been a routine stop of your van to investigate whether you were properly insured.
She said Rodwan had picked up the machete "in a rage" when he could have stopped resisting arrest, and praised PC Outten for his "considerable presence of mind and fortitude" for Tasering Rodwan despite his injuries.
PC Outten said he was very lucky to be alive, figuring that he was thankful that his head was hard enough to withstand the attack.
Graphic footage from the police officer's body worn camera showed Rodwan punching the officer before grabbing a sharpened machete as Pc Outten tried to arrest him.
Bleeding heavily from deep gashes to the head, broken fingers and a wound to the arm, the Met Police officer Tasered Rodwan twice before subduing him, the Old Bailey heard.
Social media has reacted strongly to the news that a man who attacked a London police officer with a machete had a string of convictions for violence and rape.
During the trial, PC Outten - who was dubbed "Britain's hardest cop" in the press - said he used his leg to stop Rodwan closing the van door.
He said: 'On that evening, I was doing my job, doing what I'm prepared to do, but more importantly, making sure I didn't fall because that was a distinct possibility had the assault carried on.
'Once he's begun hitting me in the head with the machete, then I realized it was escalating very soon, and I was having to now fight for my life.. "When the first shot didn't work, I remember thinking that if the second one didn't work, that would be it and I'd be dead, but thankfully it did".
The officer, who was off work for five months as a result of the attack, said he felt "no hatred" for Rodwan. "He was attacking an officer in uniform and I responded as such".
During the trial, the jury was not informed that Rodwan had already attacked two men with a machete in the room of his apartment in east London in 1996.
The accused, then known as Rodney Reid, was imprisoned in Snaresbrook Crown Court for nine years for being intentionally injured.
In an interview before the verdict, he said: 'He did what he did, he's now paying the price for it'.
"I don't feel the attack was personal".
At the time of his arrest previous year, Rodwan gave a relative's address in Luton, Bedfordshire, but went on to tell jurors he slept in his van around Waltham Forest.
