rewinding 3 phase motor to single phase

Plot size 6359 sqmtrs, Built up Area :Acc 16200 and RCC 10000 sq ft. ... sectional warping machine 5400 mm width and rewinding creel 480 spindles is available for sale. Measure resistance for each winding, resistance between two different winding and resistance between winding and motors frame. These seem to be in series but it is not addressed in the text. Did you compare your calculated number of turns per slot (62) to the number removed from the old winding? For an AC three-phase motor, you need to swap any two of the power leads (usually 1 and 3 are chosen), while for a single-phase motor you will need to refer to the manufacturer instructions or seek the assistance of a certified electric motor … Stator is made out of iron core and winding. 8 months ago Do you have a diagram for a single phase motor magnetic contactor with overload relay with no nc switch and red and green pilot light? 6. why you divide Bzr*Qp by 1.57 in step 34? Get info of suppliers, manufacturers, exporters, traders of Printing Machine … I had a lot of problems with calculation but i solved them and i got same parameters of winding as were on old one. i had rewinding 3 phase motor 45kw,FLA 80A.After installation and test run about 12 hours the motor trip again .aftet check was found the motor winding already burnt.fyi overload setting is 95A.is it any possibility of this problem.. This comment has been removed by the author. Each one is drown for different amount of pole pairs. You can detect burned motors winding by unique smell (smells like burned lacquer). You can find all information about type of old winding in "winding head". I see some light colored lines on the winding diagram - are those connection points? Use puller to remove bearings on both sides. In next steps I will show you how to analyse motors winding, disassemble motor, remove bearings, calculate new winding, rewind motor, reassemble it with new bearings and test motor. This time winding was too big and i couldn't close the cover of motor. 5 months ago Make model of coil. External diameter of statros package: Dv= 128mm; Inner diameter of stators package: D= 75.5mm; Width of stators slot: b1= 6.621mm; b2= 8,5mm. Reply In second line is measurement at 380V and third line at 400V. Bind the coils with the stator lacing thread. Resistance between two winding and winding - frame should be more than 1,5 Mohm. Created with by OmTemplates | Distributed By Blogspot Themes, As you know that we use in every place AC motor for different types of work. You can use wooden stick to put winding in slots. Tight winding well. It depends on type of isolation. I picked 0,8mm wire. Cut it and twist it as I have done on gifs. Then remove second cover. If would had 4 pole motor we would have 4 areas instead of 2 areas of magnetic field. However, some fantastic learning to be gained from this. Reply Because cage is short-circuited, voltage generates flow of electric current. It's amazing the amount of effort and detail work that goes into it. Please sir,single phase motor rewinding formula pdf send to gmail adress- pyithein654@gmail.comThank for knowledge sharing. If you are searching for rewinding of one phase motor you can find it here. If you have iron ventilator heat it. Solder and isolate them. on Introduction, Tanks alot sir giving briefly explanation . You find type of bearing on side of bearing. Put ventilator and last cover on motor. If you have any questions please ask, and i will try to answer ass soon as possible. 8 months ago. In winding books there is a lot of different types of winding diagrams. In next step you will need to heat up old coils, and conduit box must be empty. You must be careful because you can easily damage the axis of rotor. Remove covers from motor. Lubricate axis of rotor. so the friend keeps watch and enjoy it.. 2.1 Motor Ohm Values Chart; 3 3 Phase Motor Winding; 4 3 Phase Motor … Figure 11 – A delta-connected motor that failed because of a single-phase condition, Line 3 is open. My new winding was three phase single layer concentric winding. Distribution Board Wiring Diagram For Single Phase Wiring, How to Control a Lamp / Light Bulb from Two places Using Two Way switches For Staircase Lighting Circuit, Contactor Wiring Diagram For 3 Phase Motor with Overload relay, Forward Reverse Motor Control Diagram For 3 Phase Motor. Put motor in it. Hello everyone, i am Niko and, in this instructables i will show you, how to rewind and renew old three phase electric motor. On the motors inscription board we can find most useful information about motor: Before measuring remove all connections in conduction box.
