Re: (ET) Motor Break in

["Konstanty, Walter (GE Infra, Energy)" <Walter Konstanty ge com>]

  On electric motors, there is no break-in period.  DC motors are usually load tested to overload and ac motors are at least no load run.  Bearings and brushes are seated to allow immediate full load operation.  Insulation hi-pot and resistance tests check integrity of the system.

 

  On large DC machines we run them to build a film up on the commutator.  Industrial customers do not baby machines so they are designed to run at rating out of the box.

  As Dennis states, drive it like you stole it.

       What does the manufacturer recommend? If it is a brush less motor, I can't envision any break in being necessary. Drive it like you stole it. <G>

Now that I have my 65 Datsun truck running, I would like some
suggestions on breaking in the motor.
At present the motor probably only has ~ 2 hours on it.

Should I try to drive at a certain RPM ?
Is keeping the RPM higher better than lower ?
Any other suggestions ?

Motor - FB1-4001A Advanced 9".
(13) 156V of  Odyssey PC-1750 Batteries.
