Any single-phase a.c. generator producing more than 2.5 HP or 2 kW - at the required voltage.
how reversing an ac single phase induction motor to wark as induction generator
If the elevator has a single-phase motor, the diesel generator can also be single phase provided the voltage and VA ratings are compatible.
Terminology gets misapplied but a 3-phase converter produces a 3 phase supply from a single phase supply. The only proviso is that generator, converter and motor are all suitably rated and compatible.
The winding design of the motor will not economically allow this to work. You would have to drive a 3 phase generator to supply it.
To answer this question the voltage of the motor is needed.
We can convert a 3 phase ac motor into generator by changing phase sequence of the ac input cable of that motor
single phase fully control converter
A simple Rotary phase converter is just a motor generator set. An electric motor running on the input voltage/current/phase/frequency. it drives a generator that supplies a different voltage/current/phase/frequency. So an electric motor and an electric generator connected together mechanically, either on the same shaft, or via gears, constitutes a Rotary phase converter. the above is incorrect, the motor/generator is the same motor, just one 3 phase motor is needed, it will run on T1 and T2, and put out L1, L2, and L3. You just need to know how to wire it up and what to do to get it to spin over on simple single phase 220, it will create three phase 220.
Single phase motor winding is often checked just by listening to the noise that the motor is making. An experienced person can tell if the motor is working at single phase or double phase.
There is no such thing as a two phase load any more. Any two legs from a three phase system are classed as single phase. If this single phase load is connected across the generator it will induce an imbalance in the output voltages of the generator. This is one reason that single phase loads on a three phase generator should be shifted around to find the best possible balance.
It's an electrical generator converting mechanical power into electrical power. The electrical power comes out in the form of single-phase alternating current.
The type of backup generator should match the type of utility service you receive. If your utility power is single-phase (almost all residences in the US are), then yes, your generator should be single-phase as well.
