Troubleshooting single phase motor issues
WebAug 1, 2002 · Troubleshooting single-phase refrigeration compressors requires a technician to have a proficient understanding of capacitors. The start capacitor is one of two types of capacitors that can be found on single-phase compressors. Understanding how to troubleshoot and replace a defective starting capacitor is essential when working with … WebDec 7, 2016 · If not, motor performance will suffer and damage to the motor coil can occur. Since the VFD severs the direct connection of the line supply to the motor, it acts as a buffer and actually protects the motor from a phase to phase voltage imbalance. A VFD can even operate a three-phase motor on a single phase line.
