So you just burned your motor or you want to rewind your motor for more power/torque, but are confused as to how to wind the motor. Just enter the no of poles ( the no of stator arms) and the no of magnets in this calculator and it will provide a winding schematic.
Jun 19, 2018 If you are searching for rewinding of one phase motor you can find it here. In this insctructables, i am going to make step forward. 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. Figure 3 Relationships Between Power, Current, Power Factor and Motor Load Example: Input Power Calculation An existing motor is identified as a 40-hp, 1800 rpm unit with an open drip-proof enclosure. The motor is 12-years old and has not been rewound. The electrician makes the following measurements: Measured Values: V ab = 467V I a = 36 amps. The winding calculator allows you to find the optimum winding layout for your electric motor in a fast and convenient way. You can investigate three-phase integer-slot, fractional-slot and concentrated windings, both with single and double winding layers where appropriate. The calculation will be performed for the air-cooled, three-phase motors for continuous duty cycle S1, standard efficiency, 50 or 60 Hz, SF 1.00, lap or concentric, single or double-layer, for the maximum power from the given iron core. Please, carefully review the information needed, and be aware that more details gives more accurate results.
Induction Motor Rewinding Calculations
The no of poles/stator arms of the motor are always in the multiples of 3 and hence the motor has 3 phases. Each phase is winded separately. If you mark any stator arm as phase one, then the next stator arm of the same phase can be obtained by adding 3 to the first stator arm.
Induction Motor Winding Calculation
So stator arms 1, 4,7,10…ect belong to one phase. Similarly stator arms 2,5,8,11…etc belong to phase two and stator arms 3,6,9,12.. belong to phase three.
