B) Reverse any two of the supply leads, anywhere in the supply will do, ie. in the motor connection box or in the starter or isolator. But dont change the phase colour markings around, (IF they are identified, and they should be) Old colours = RED/YELLOW/BLUE
New colours = Brown/Black/Grey
The above applies to a DOL motor, if it's a Star delta with a starter it will be easier to reverse any two lines in the isolator or supply INTO the SD starter.

Just reverse the phase connections to the motor. If you wish to do this on a regular basis you could install a device called a 3 pole reversing contactor, which is like a big relay, that will do the job at the flick of a switch.
Have a look in the RS catalogue on their web site RSWWW.COM and look up catalogue part number 758-765.

Just swap 2 of the phases over in the motor or plug or even the isolator ( dont forget to turn the power off first! then turn it back on, if it has not changed direction swap the one you have not moved with one you have and keep trying that until it spins the way you want.
Just dont move the Neutral if it has one

it might remember on various variables, if there is a few residual magnetism in the motor it might desire to initiate performing as an alternator (AC generator) the outcomes of that may not common to foretell. despite if it rather is an extremely great motor utilising rigidity lubrication, bearing harm is a probability because of the fact of oil pump no longer functioning. If bypass situations enable the motor to very much exceed conventional velocity, catastrophic harm would result. i'm guessing NRV is something like "Non return Valve", usually spoke of as a verify valve in the U. S.

Change two of its three phase wires over. This will reverse the direction of the rotating magnetic field in the motor's windings and thus its direction of rotation.

Hi Paul,
All you have to do is change the wires over in the plug. This should reverse the motor for you.

You are all f'ing dumb...the only difference in the phases is 1/180 of a second...you need to change the "rotation" of the phases...ie does it peak A-B-C or does it peak C-B-A...if you change any of the 2 phase wires it will cause the roation to change A-B-C to C-B-A (or the other way around).

Presumably you just reverse the polarity of the electricity - swap the wires over.

Unbolt it, turn it through 180 degrees and remount it, the rotation has changed direction

Juist swap over two of the phases and it will run backwards.
