Compressor Rotor Lock. Trane XL 20I Locked rotor compressor due to failed start capacitor This one covers determining if a compressor has failed due to locked rotor.This video is part of the heating and cooling series of training videos made to ac. A mechanical issue with the compressor (bad bearings or windings) may take longer to present themselves on every start up
Sheet Metal Pressing Stator and Rotor for Electric Compressor Motor from metalli.en.made-in-china.com
This one covers determining if a compressor has failed due to locked rotor.This video is part of the heating and cooling series of training videos made to ac. Burnt contactors, loose wire connections and wire splices can generate a voltage drop & a locked compressor
Sheet Metal Pressing Stator and Rotor for Electric Compressor Motor
The rotor rotates around the stator, and a "locked" rotor draws higher current and doesn't spin Fault 4 (Locked Rotor) - is an electrical or mechanical issue with the compressor Inductive loads produce back EMF at the beginning and create inductive reactance, which is why you see higher current.
RoemheldRotorLock1024x803 ROEMHELD North America. This one covers determining if a compressor has failed due to locked rotor.This video is part of the heating and cooling series of training videos made to ac. There is another current measurement that should be made.
HOW TO DIAGNOSED A LOCKED ROTOR COMPRESSOR (and what is the solution. A voltage drop of 10% or more during locked rotor conditions should be evaluated--check for tight wire connections all the way back to the breaker panel. Calculating the Locked Rotor Amperage (LRA) on a compressor is a crucial step in the maintenance and troubleshooting process
