single phase motor L1, L2, L3
(OP)
L1 is hot, is L2 common and L3 gnd? Searching the entire net and all I can find L1, L2, L3 is 3phase.

I m aware that L1, L2, L3 is 3 phase, but...and I also have another 110vac mtr that has the hot marked L1 and the common marked L2. Make a rule and ppl brake it.
RE: single phase motor L1, L2, L3
On 1 phase equipment intended for use in the US, they will often mark the leads as "L1 and L2" because of the fact that they may be capable of being used on a 1 phase 120V circuit, OR reconnected to be used on a 1 phase 240V circuit. Yes, in the 120V circuit the designation could show L and N, but L1 and L2 is fine as well. On the 240V circuit however, L and N would be incorrect. So showing L1 and L2 is the universally acceptable alternative.

It's 3 phase.

Blimey! We've been doing it wrong in the UK for a hundred years...

Or did you interpret that as meaning "us" instead of US, and then took the "Royal us" version to mean people on the island of Great Britain?

Now, in North America, if we connect 240 V transformers in wye we will have a 240/416 V system.
If we now take 120 volts from a center tap on a 240 volt winding, one end of the winding will still be connected to the system neutral. Hence the Neutral/0V-115V-230V configuration in the UK.

Yes, but those motors do not have a L3. The "TEFC 3P" tells you it's 3-phase. Typically, there is a seperate square for "Phase" on the nameplate but they didn't bother clarifying that data on this motor.
