Permanently Split Capacitor (PSC) Motor – Technical Guide [PDF]
The permanently split capacitor (PSC) motor is a commonly used single-phase motor in various applications. ... PSC motors typically provide lower starting torques compared to motors equipped with a separate starting capacitor. The starting torques of PSC motors typically range from 30% to 150% of the rated torque. ... Using this method, the ...
capacitor
We want an input voltage (to the load) as smooth as possible because sometimes a device acts weird due to a power supply with too large of a ripple. When the load is so heavy that the ripple is too large, you can use a bigger capacitor, because that smooths the line more. Therefore, it depends on the load what value you need for a capacitor.
measurement
The people who service things like central air etc who see a lot of failed motor-run and start capacitors tend to only go by the main value. The hand-helds they have can only measure that. However, these are mostly polypropylene film capacitors. Other equipment has aluminum electrolytics that often have high ESR failures.
