How does a run capacitor value affect the motor?
Start capacitors will typically have a much higher capacitance rating than run capacitors (100 to 1600 µF vs. 5-100 µF). This is because they need to be able to store more charge in order to provide enough power for the motor''s startup phase.
Capacitance vs Frequency | A Comprehensive Analysis
Effect of Frequency on Capacitor Impedance and Phase Angle. For ideal capacitors, impedance is purely from capacitive reactance XC. However real capacitors have parasitic resistance and inductance. This means the impedance has a phase angle between 0° and -90°. For an RC series circuit: Impedance Z = R 2 + XC 2. Phase angle θ = arctan(XCR)
