S Band Radar

Here's the problem: "all the phase ohms are 34 amps"

I guess that you meant to say 34 Ohms.

Did you check the bearings while you had the motor out? They would be my first suspect.

Knowing not much more than you've said, all I can say is if the motor resistance is OK and the current isn't, then it has to be the supply to the motor that is not correct. Check your voltages.

Onboard a ship you probably have a corrosion issue, check the bearings and the gearbox, could be an interference issue, did you run the motor while it was removed from the radar? check downstream from there.

There's no hope of ever getting this working again.

I'd scuttle the ship and swim to shore.

LOL!

From the specs that Lyn so graciously provided you need 3 phase power to the motor. if you only have 2 you have your problem figured out.

Please discuss the problem directly with the equipment supplier.

You have lost a motor supply phase.

Start measuring voltages towards energy source.

If it is right that only two phases are operating at the motor, that is likely to be the cause of the overcurrent. In effect, the two live phases are acting as a single phase supply across the motor which will be stalled, drawing excess current.

Checked the bearings they are good.

I have checked voltages 452,452,452, 60Hz between phases.

Yes we run the motor while it was removed from the radar it was taking 1 amps each phase

There is no problem with the energy source

Yes, you are rite Geoffrey36 only two phases are operating at the motor, which is likely to be the cause of the over current.

There is one circuit board between the supply and the motor to reduce the starting torque and to start the motor smoothly. Like a soft starter, that circuit board has failed and it was tripping on over load. The circuit board only controls one phase. Now we have connected directly and running it. Thanks for all your response.
