Copeland compressor winding resistance The resistance between start(S) to common(C) is typically three-to-five times higher than run to common winding. Finally, the resistance between run and start should be the sum of S to C and R to C. 2 132 0. 191 The resistances are as follows: Rv = Rv = resistance of "full winding" st R1T = resistance of 1 part-winding nd R2T = resistance of 2 part-winding R1T R2T R1T + R2T Part-winding motor 3/5 - 2/5 (BW…) 7. Remember, there should be a measurable resistance through each winding. also when ohming out compressors the reading is not too important as the difference between each winding. No, note that the ZS09-19KAE-(TFD, TFE, TF7, TF5) three phase motors use a modified ""Scott-T"" connection and don't have equal resistance on all three windings. If the motor winding resistance needs to be measured the diagrams below show the internal connections for the motors used on Copeland semi-hermetic compressors. The lowest resistance will be found between the run(R) to common(C). 6 316 108 0.

Two windings will have equal resistances and the third winding will be lower than the other two. that model number is ***** a valid number for a copeland compressor, please check that number or if you can take a picture of the nameplate on the compressor and post it here by using the paperclip icon that would help too. 4 Resistance RV of the complete winding is measured with bridges between terminals: Resistance R1, without bridges between terminals hi i am dan i can help you with this. 1 Present motor versions (C, E &A) Figure 1: Single-phase, motor code C Figure 2: Star-Delta (Y/Δ), motor code E Figure 3: Part-winding 2/3:1/3, motor code A Across the Line Part Winding Start Winding Resistance Model Volts PH Max RLA LRA Max RLA LRA Line to Line (Ohms) Electrical Data - Copelametic Large Refrigerant-Cooled Compressors See Section F Introduction for more information. 4.
