its answer is YES because 220 is a phase voltage in three phase system and line voltage for three phase system is 220*1.732=381 or 380. thus motor runs. <<>> The above answer is wrong. Just because one leg to ground voltage is 220 volts on a 380 volt system does not allow the three phase motor to run off of one leg of a three phase system. A three phase

Single-phase induction motors that have two capacitors have a higher torque capability when starting and accelerating. The starting capacitor is larger and thus allows a higher current in the starting winding and a greater phase shift of the current in that winding. However, the capacitor and starting winding are not designed to carry that

And no, you do not directly short a capacitor with anything like a screwdriver. It''s only done with a resistor to take up the load.

I''d assumed that they usually run at the same output voltage as the input so 220v 1ph in and 220v 3ph out, so to run a standard 3ph motor, you have to rewire it from delta to star.

Key Takeaways. 🔹 Starting capacitors provide an initial boost and are temporary, while running capacitors stabilize performance and remain connected. 🔹 Use 30 to 50 µF per kW as a starting guideline for starting capacitors. 🔹 Running capacitor sizing depends on motor current, voltage, and frequency. 🔹 Voltage rating should be at least 30% higher than the supply voltage.

The formula for a capacitor is I = C dU/dt . If you want the ripple to be less than say 10V all the symbols are known allowing you to calculate the capacitor. Because I don''t have a calculator here, 3500W/about 300V is about 10 A. DT is 10ms, so you get: C = I dt/dU = 10A.10ms/10V = 10mF = 10000uF. Quite a lot for such a large voltage.....

Always make sure that it is a capacitor for 230V AC (thus non-polarized) and for continuous motor operation. Plastic-wrapped capacitors (called "self-healing") should be preferred to those packed in aluminum (old generation). To reverse the direction of rotation of the motor, it is necessary to cross the 2 wires of the sector. Mounting:
You get surely better performance with real 3 phase voltage than with a capacitor. The connection of a capacitor to a three-phase motor for single-phase operation is called a Steinmetz connection. If you search "Steinmetz connection" you will quite a bit of information about that.
You might be able to find a VFD with a built-in voltage boost circuit to give 380 volt, three-phase output with 220 volt, single-phase input. Otherwise you would need an input transformer for the VFD and a 380 volt VFD that accepts single-phase input. I don't know what all the options are with a Steinmetz connection.
but it seems to me that as the motor's basic mass and windings haven't changed you'd need the same sized cap; typically in motor capacitor specifications the voltage range given is a safe upper limit and it's ok to use, for example, an XXufd starter cap or run cap rated for 380V on a 240V application.
