Wiring nvr switch query

I've just removed this small motor from my lathe with the intention of using on something else, it has a 2 direction switch wired up, if I could have some input from you clever electrically minded folk, I want to wire it with a simple NVR switch, no reverse needed, the motor has 2 live and 2 neutral, how do you do this on this setup with 4 wires?

Please excuse my ignorance on electrical matters.

I'll upload a photo in a moment.

That looks like a start relay so the motor may have start & run windings. Some do. That could be connected to a timer or a centrifugal switch on the motor shaft.

Thanks Steve, do you know how to wire up a simple 2 wire nvr switch rather than the 2 direction switch currently fitted?

From your picture I would not know. Without a wiring diagram I cannot help, sorry. Maybe someone will be along who can help.

Sometimes there is a wiring diagram on the inside of the cover but failing that is there a plate on the motor. There seems to be markings on the cables that may give a bit of a clue, draw a sketch with cable markings and conections woukd help.

Any Control Fitted into the mains lead that is a D O L has NVR and Thermal overload wiil not affected any other motor controls that hve not been touched..

I am struggling as to what the NVR means. Is it a No volt relay. Like a lot of new pillar drills/ bandsaw & the like have fitted. Which are like a latching push start & combi stop button. Doing away for the need of a contactor.

NVR is No Volt Release

so a contactor is nvr

the modern little green and red start stop modules have a latch which is magnetically held in so when power is interrupted the switch latches off so when power is resumed a machine won’t start up
