Can the three-phase generator wiring diagram lead to only one phase
The three-phase generator wiring diagram can only lead to one phase, that is, the three-phase generator is changed to a single phase. There are three specific wiring methods, as follows:
Method one, when the three-phase motor is star-connected
Method two, when the three-phase motor is a delta connection
The main points of forward and reverse rotation: change the wiring of the capacitor end.
1.Calculation method of capacitance
The calculation formula of the starting capacitor and the running capacitor, the formula of the running capacitor: C = 1950I / Ucosφ, C is the running capacitor capacity (uf-micro method) I is the rated current value of the motor (A) U is the rated voltage, since we are here to change Single-phase operation, so the rated voltage is 220 volts. cosφ is the power factor, which is marked on many motors. The starting capacitor is generally 1-4 times the running capacitor.
2.Empirical formula for capacitor capacity
100W power corresponds to a capacity of 7 microfarads, that is, a 1KW motor can use a capacitor of about 70 microfarads. This value is only an approximation and can be adjusted according to your own load situation.
It is only recommended to change the motor below 1.5KW, after which the power will be attenuated, and no heavy load can be carried. If the power is slightly greater than 1.5KW, another starting capacitor needs to be added.
Method three: Such changes are rare, as shown below
