Typically the run capacitor on a 5 hp. motor is around 30 µF - 40 µF 370VAC Typically the start capacitor for a 5 hp motor is around 600uF To take a stab at answering "how to convert a 3 phase motor to run on single phase power" I found a variety of answers ranging from "it''s easy" to "it''s a really bad idea, even dangerous".
Limitations of Single Phase Motors. Even with the additional auxiliary winding, a single-phase induction motor suffers from several limitations compared to a three-phase motor. The phase shift provided by a run capacitor changes with the motor''s speed, which means efficiency is not consistent as the motor changes speed.

The issue there is the reference used. One needs a 3 phase motor/generator about 1.5-2x the expected load (5hp can drive a total of 3hp.) A delta connected 3 phase motor is needed to allow neutral reference (that is, 120 as well as 3 phase 220 from the same system) but a wye motor works fine for just 3 phase only.

Figure 2 illustrates the three-phase AC power applied to the stator windings. The three-phase power produces a peak voltage every 120°. Figure 2. The three-phase waveform. Image used courtesy of Amna Ahmad . Now, notice the three separate phase windings in the stator in Figure 3. The phase windings are arranged sequentially around the …
Unlike three phase motors, which have three sets of windings that are spaced 120 degrees apart, single phase motors only have one set of windings. This means that they rely on the design of the motor and various capacitor components to create a rotating magnetic field. ... To start a single phase motor, a capacitor is used to create a phase ...
Figure 3 is a graph of current draw from the 1⁄2 hp fan motor over a 1-minute period using working, dead, and weak start capacitors. The fan with a working start capacitor uses a short spike in current draw (27.2 amps at 120 volts) to spin the fan up quickly and then drop to an operating current of 6.1 amps.

$begingroup$ For a practical usage you should also be aware of the traditional method of having a larger unloaded 3-phase motor run as a rotary converter (after capacitor start), and more likely the modern method of synthesizing 3 phases with a VFD fed with single phase, de-rated per the manual for the increased load on its rectifiers and capacitors which …
Once three phase motors start, they run on single phase. Capacitors store a high voltage charge while the motor is running for the next startup (hence the reason a …
A typical motor start capacitor. A motor capacitor [1] [2] is an electrical capacitor that alters the current to one or more windings of a single-phase alternating-current induction motor to create a rotating magnetic field. [citation needed] There are two common types of motor capacitors, start capacitor and run capacitor (including a dual run capacitor).[2] ...
There are basically three approaches to running a 3-phase motor from single phase power. None of them is as convenient as buying a single phase motor in the first place. Static phase converter. This involves a …
Start Capacitor Selection Guide. A start capacitor is used to briefly shift phase on a start winding in a single phase electric motor to create an increase in torque. Start capacitors possess a very large capacitance value for their size and voltage rating. As a result, they are only intended for intermittent duty.

When it comes to wiring a capacitor for a three-phase motor, the process is slightly different from single-phase motors. In a three-phase motor, there are typically two types of capacitors used: a start capacitor and a run capacitor.
