If a wrong capacitance value is installed, it will cause an uneven magnetic field around the rotor. This causes the rotor to hesitate at the uneven spots, resulting in irregular rotation, especially under load. This hesitation can cause the motor to become noisy, increase energy consumption, cause performance to drop and the motor to overheat.
What is the tolerance for the run capacitor's capacitance?
- I have a compressor with 50 µF run capacitor. The capacitor went bad.
- Manual reads that the run capacitor should be 60 µF.
Which one would you go with?
What is the tolerance for this capacitance?
EDIT: there is also a separate Start condenser in this motor setup. The question is only about the Run capacitor.
