If you have one, you cant skip titles Winding diagram What is winding diagram Winding diagram is diagram which helps you rewind motor.
Easa Motor Rewind How To Rewind AndIn this instructables i will show you, how to rewind and renovate old electric single phase electric motor.In next steps I will show you how do disassemble electric motor, remove bearings, make winding diagram, rewind motor, chose right capacitor and reassemble it with new bearings.It took about two days to rewind it, replace all old parts and reassemble it.Easa Motor Rewind Download Step 1Add Tip Ask Question Comment Download Step 1: How Do I Know If I Have Single Phase Motor Single phase motor usually has two coils, main with bigger resistance (generating a pulsating magnetic field) and auxiliary with smaller resistance (gives motor a direction of rotation). Its value is different for different electric engines (for smaller electric engines around 20 microF). Start capacitor (connected with centrifugal switch, higher value capacitor) Picture 1: Scheme of single phase electric motor Picture 2: Run and star capacitor Picture 3: Wires from stator (there should be 4 wires from stator) Add Tip Ask Question Comment Download Step 2: Tools Rewinding and disassembling motor is very time consuming work, if you dont have professional equipment. You will need following tools: - Basic tools (screwdrivers, hammers, wrenches.) - Pulleys for bearings - Chisels, to cut off old winding - Butane torch (or other heating device) Special Material: - Copper wire - Isolate paper - Stator lacing thread - Spray Lubricant (WD-40 or similar) - Motor lacquer Add Tip Ask Question Comment Download Step 3: Disassembling Motor Take few pictures of motor, and Remove the fan protective cover. Usually the cover is not screwed with screws on housing but its just plugged on housing. Put all removed parts of motor in one box so you dont lose them.

As you see on picture our motor fan is broken and we need new one.

One of the motors winding burned out (black colour and smell of burned lacquer). I find out that bearings are broken too (when you spin it, it creates loud sound). Add Tip Ask Question Comment Download Step 7: Disassembling Motor Unscrew the screws securing the front cover (as youwe done 2 steps before). Gently remove the front cover with rotor out of main housing and put it in the box with other parts. Add Tip Ask Question Comment Download Step 8: Disassembling Motor Unscrew the screws securing the top cover. Remove the top cover and sealing and put it in the box with other parts. Take few pictures of electrical installation and remove all the wires and electrical clips. Remove capacitor, if you have one on motor (our was cut off). Add Tip Ask Question Comment Download Step 9: Motors Inscription Board Try to write down all information from inscription board. There are some useful information on it (voltage, current, number of turns per minute, capacitor.). Add Tip Ask Question Comment Download Step 10: Winding Diagram In next steps we are going to make winding diagram.
