WebOct 26, 2024 · Winding resistance test measurements detect problems in motors that other tests may not find. These problems include: 1. Partial or fully shorted coils. 2. Poor crimps or connections. 3. Imbalance between phases (improper turns on phases) and incorrect coil (phasing) connections. WebJan 19, 2015 · The National Electrical Manufacturers Association (NEMA) defines unbalance as a percentage: % unbalance = [ (100) (maximum deviation from average volt-age)] ÷ average voltage. To help equipment operators determine acceptable levels of unbalance, the NEMA has drafted specifications for multiple devices.
