Nah doesnt exist
capacitive start motors start by themselves however a normal single phase induction motor requires a starter motor to 'kick-start' the motor into action.
For a 240-volt single-phase induction motor, a two-pole motor starter is typically required, as it connects to the two live conductors of the single-phase supply. For a 440-volt three-phase induction motor, a three-pole motor starter is needed, as it connects to the three phases of the three-phase supply.
This depends on the voltage, and whether it is a three phase or single phase transformer.
You never need a starter for a three-phase motor.
By having a transformer with 3 phase input and single phase out put
A Scott transformer converts 3-phase to 2-phase and vice versa, so if you get a Scott transformer it can convert a 2-phase supply into 3-phase for the motor. Caution: the 2-phase supply has to be a genuine 2-phase as defined, with 90 degrees phase between the two phases, and these are extremely uncommon. A Scott transformer CANNOT be used with the split-phase supply found in many US homes which have a 240 v single-phase transformer with the centre earthed and connected to a neutral wire to produce two 120 v circuits.
Harmonics are really not needed in single phase transformers.
Your question is rather vague. If you are asking what do you call a group of single-phase transformers, connected to supply three phase, then the answer is a 'three-phase transformer bank'.
A single-phase transformer works with a single-phase supply, while a 3-phase transformer is used with a 3-phase supply. A single-phase transformer has 2 wires on the primary and secondary (ignoring taps) while a 3-phase tansformer has 3 or 4 wires on the primary and secondary.
Consult with the owner manual for the correct steps in sequence.
it have a water container. the water pressure in the container varies the self starter works.
By design are you going to wind the transformer yourself? In your design you need a 5:1 ratio. On the output side of the transformer any two legs of a three phase transformer is considered single phase voltage. Good luck on your project.
