In case of one phase of three phase supply gets disconnected than the motor will still run in two phase with humming sound but will not be able to take load. Hence, you need to check three phase supply and winding continuity.
My 3 phase motor becomes hot to touch after 2 to 3 hours. I opened it and re-varnished the winding. Even before re-varnishing it, I can see that it still looks good. I replaced both bearings which does not look like there's a problem but after all these, the motor is still hot to touch. I checked the ampere reading and they are all below 4.5 amps..The 1.5hp brake motor is rated 4.6 Amps. What could be the problem ?
1.5HP Motor shall draw 2.25A Current (Approx 1.5Times of HP Capacity for 415V,3-Phase AC).Your motor seems to draw more current.High current will lead to rise in temperature and also heating. Hence please rewind the motor with thicker gauge super enamelled copper wire than existing winding if space is available in the slot.
Also, please disconnect the motor from load and give supply and note down the no load current. It shall be one third of full load current. i.e 0.75A. If it is drawing more current than their may be winding problem. If no load current is OK than please check the mechanical load.There may be problem.
this is brilliant ....nice rewinding skills',i have learned more than expected.

Sir one question 3 phase electric motors goes to 1phase but won't go to 2nd or 3rd phase but can hear humming sound whats wrong with it?

See your motor impeller
sir kisi bhi coil se le date hain
what is that liquid that you poured on the insulation called and where do you buy that ?
The liquid is golden varnish. This will be available in hardware shop.
Nice video! Can you help me in making 3 phase motor out of 1 phase motor? It has 24 slots and it is on water pump.
Assalamu alaikkum Baba jee.very Good things you are doing but I need to know how to make drill machine armature rewinding please upload.
Very very very good sir
is it delta or start connection?

Nice Video Sir. Can you give us the list of material needed for rewinding.Thanks and Godbless you!
The materials required are:-
1) Super Enamelled Copper Wire of required SWG
2) Fast Drying Varnish
3) Cotton Tape
4) Mylar Sheet/Paper
5) Triplex Sheet/Paper
6) Kerosene to wash
7) Sand Paper for cleaning
8) Solder
9) Glass Fiber Insulated Sleeve of required size
10) Glass Fiber insulated copper connection wire of required diameter
How about to connect the coil connection.Is it safe to use a soldering iron?
Thanks for the reply.
Thank you for your info
