It want turn on in smells burned - Jack Lalanne Power Juicer 250 Watts

You may just be overloading the circuit. Easiest correction - unplug something else that's running (or turn off a light) on the same circuit and see if the breaker still shuts off.
But wait - also important - was there any burning smell? If so, this is dangerous. It's a short circuit that occurs when a "hot" wire (black) touches another hot wire or touches a "neutral" wire (white) in one of your outlets. You should not use that outlet and have an electrician look at it. Or it could be a ground fault (similar to the short circuit - when a hot wire touches the ground wire on the side of a metal outlet box which is connected to the ground wire. For either of these, you need an electrician.

It could mean burnt motor, but it could mean that it's simply got gunk in it, and it needs cleaning/lubricating. You'd have to take it apart to tell. A burnt motor has a very specific smell. If you take it apart, and there's no burnt smell, likely cleaning and lubricating will fix it.

disassemble clean and assemble paying attention to condition

noise from bearings going out/screeching ???
noise from unbalanced load/ lots of vibration??

is any part getting warm ( turn upside down to check ) ( hold or place on thick layer of kitchen towels

be aware if it is old ~ 20 yrs give or take 20 yrs getting a new juicer will be less hassle than trying to repair

You burned out the motor. Get a new juicer.

Depends on how old it is. It could have bad brushes in the motor or it may have burned up. Do you smell burned insulation etc.? If it just quit there may be a problem with the switch or the cord. Wiggle things and replug etc. to see if that is the problem. Otherwise, you may need a voltage tester to check for power.

There may be an overload switch somewhere on the unit, it will just be a small button projecting from the underside most probably or in a small hole. If there is, just depress it. If the unit actually burned out yu would have seen smoke and smelled it.

these juicers have a tiny little motor. once they smell bad, they are shot. not worth repairing. Joe
