So, what to do with only single-phase power? You use caps to generate a second phase. That way, the core will have a magnetic field that instead of moving back and forth between two poles, the field moves around the poles in sequence and the core can just follow it. Motors may have 1 or 2 caps. It may have a "run" capacitor.

6 FAQs about [Capacitor four-core welding method]
What is capacitor discharge welding (CDW)?
Capacitor Discharge Welding (CDW) is a welding process that utilizes the discharge of electrical energy stored in capacitors to create a localized, high-intensity heat source for joining metal components.
Why is a capacitor used in welding?
A capacitor is used in welding to store electrical energy that can be rapidly discharged during the welding process. This discharge provides a high-intensity current flow, generating the heat required for melting the metal surfaces and forming a weld joint. What size are welding studs?
How does a capacitor discharge weld work?
Capacitor Discharge Welding works based on the principle of discharging stored electrical energy from capacitors through the workpieces to create a weld. The capacitors store a high voltage charge, which is discharged through the weld zone, generating an intense current flow for a short duration. The equipment used in CDW typically includes:
What are the limitations of capacitor discharge welding?
Size and thickness limitations of workpieces: Capacitor Discharge Welding is best suited for small-scale applications and workpieces of relatively small size and thickness. The equipment and process may have limitations when it comes to welding large or thick materials, as the heat generated may not be sufficient for effective bonding.
Are electrolytic capacitors a viable alternative for large capacity CD welding systems?
Electrolytic capacitors (E-caps) offer a potential alternative for large capacity CD welding systems. E-caps incorporate an electrolyte impregnated into a separator. The separator is then sandwiched between anodic and cathodic foils. A dielectric is also used to prevent direct contact of the foils with the electrolyte.
How does a CD welder work?
A CD welder works by storing electrical energy in capacitors and releasing it in a rapid discharge through the welding gun. The high-energy discharge creates intense localized heat, melting the metal surfaces and allowing them to be joined together. What is a capacitor discharge stud?
