3 phase to single phase

[TCB]

any one tell me how to make a 3 phase motor run on single phase

Sure:

Phase converter, Rotary (higher demand) or static (lower demand but cheaper)

VFD with single phase input capable

Single phase motor driving a 3-phase motor with exciting the windings of the 3-phase motor (not very good)

an engineered capacitor bank design for the motor and load. (not very feasible)

Generator (costly)

Google "Phase converter" and it will come up with many options.

If it's one motor (or a couple that always run at the same speed at the same time), I'd use a VFD. Multiple motors that do not run at the same time, I'd use an RPC.

Two single phase transformer hook them up in a open delta setup it will allow 58% of the transformer rating. look up a open delta hook up.

True, but to feed an open delta transformer bank, you still need a three phase supply, but the O/P desires to work a 3 phase motor from a single phase supply.

Open delta transformer banks have the advantage of requireing the purchase of only two transformers instead of three, but dont create 3 phase from single phase.
