Introduction:
The SAGEAYCOS mechanism is the Alternative
System of Electrical Generation by Self-Induction and Simultaneous
Cogeneration.
The work is undertaken to design a basic system
for application to the aeronautical, automotive, and naval industries with the
goal that each country can apply it to any means of transport it desires, thus
facilitating the life and development of our people, as well as preventing
further deterioration of our ecosystems, maintaining a circular economy with
sustainability capabilities.
We will begin our description with data taken
from AI information regarding calculations for the respective capabilities of
each vehicle and the availability to apply them to each means of transport,
whatever its function.
In the first case, we will take as a pattern a
freight or passenger transport train and the steps that will have to be taken
to apply this mechanism (Sageaycos) to this modality.
A modern freight train requires a power of 3000
to 6000 horsepower (HP), and in this case our objective is to apply the
Sageaycos system as a fully self-sufficient operating mechanism independent of
any other.
Main engine:
An electric motor drives a high-power electric
generator, which in turn drives a high-power motor—in this case, a
3000-horsepower (HP) industrial motor. This requires a high-power industrial
motor with a minimum capacity of 2500 kW to 3000 kW, or 3100 kW to 3750 kW, to
account for starting current peaks.
Calculation and key
factors:
A power conversion of 3000 HP is approximately
equivalent to 2,238 KW of pure mechanical power at the motor shaft.
Engine efficiency:
No motor converts electricity into motion with
100% efficiency. Considering the standard efficiency of 93-95%, the actual
demand exceeds 2,350 kW to 2,400 kW continuously.
Starting current:
If the engine starts directly, the demand can
increase to 3 to 6 times the nominal power, requiring a generator with a much
larger reserve or a soft start system (variing frequency) to mitigate the
impact.
Generator type:
A low-speed generator is required: 1500
revolutions per minute (rpm) of 50 Hz or one of 1800 revolutions per minute of
60 Hz , it is clarified that the calculation is for a 3000 horsepower (HP)
train.
To power a 6000 horsepower (HP) generator, that
is, to power 6000 horsepower (HP) electric motors, a large-scale industrial
generator is required, specifically a medium-voltage generator of at least
5000KW to 6000KW, equivalent to between 6,250 KVA and 7500 KVA.
Key sizing factors:
A base power rating of 6000 horsepower (HP) is
approximately equivalent to 4,476 kW of pure mechanical power. Considering the
typical efficiency of a large industrial engine (90% to 945%), the continuous
power demand is above 4,700 kW.
Starting current:
Depending on the motor starting method (direct
start, star-delta or soft frequency inverter), the initial current peak may
require a much higher capacity in kilowatts (KVA) to avoid a critical voltage
drop.
System type:
At this power level, the equipment must operate
at medium voltage (for example: 4.16 KW; 13.8KW) and requires industrial
generators.
The trains will have an electric traction motor
for each axle that moves the pair of wheels on its axle.
Sageaycos devices to
start any type of vehicle.
A 24-volt direct current battery, of any type:
dry, electrolytic, gel, etc.
A pure sine wave power inverter, depending on
the frequency used in each country, will operate at 50 Hz or 60 Hz, with a
24-volt DC input and a 220-volt AC output. This power inverter can have a
capacity between 10,000 and 15,000 Watts.
A 1 or 2 horsepower (HP) electric motor with
1500 or 1600 rpm, depending on the type of alternator we are going to use,
which must be within that number of revolutions per minute, will be coupled within
the system, since this motor will be the one that will give the necessary
revolutions to feed the alternator whose function will keep the 24 volt direct
current (DC) battery charged, said battery will be fed back by this system
which connects directly to the 10-15 KW 220 volt alternating current (AC) power
inverter, the 1 or 2 horsepower motor is connected to the inverter. Here we
calculate the difference in motor consumption, which will be between 750 and
1500 Watts. Taking into account the startup peaks (approximately 20%), we will
have values giving it an advantage between 900 and 1800 W. This leaves us with
a consumption difference of approximately 9000 W for the 10000 W inverter and
13200 W for the 15000 W inverter. This is to calculate the consumption of the
motor that we will also connect to one of the inverter's outputs. If it is a 5
horsepower (HP) motor, it will give us a consumption of 3750 Watts. Adding the
20% startup peak, we will have a consumption there of 4500 Watts, sufficient
capacity for the chosen inverter. This 4,500-watt load, which includes peak
loads, is added to the load of the 1 or 2 horsepower motor that drives the
alternator to charge the battery. Recall that we assigned a nominal value of
between 700 and 1,500 watts for a peak load delegated to the approximately
6,000-watt inverter, leaving a margin for any additional devices. However, we
still need to connect the 5-horsepower motor to the industrial generator to
power the 3,000 or 6,000-horsepower electric motor that will drive each axle of
the freight or passenger train, or alternatively, the propeller of a river,
sea, or submarine vessel. This can also be applied to electric vehicles of all
kinds.
Aeronautical industry:
One device must be installed per turbine. For
aircraft with 2 MW (Megawatt) turbines, high-power electric generators, also
rated at 2 MW, must be installed to operate these turbines. The generators will
operate at either 50 or 60 Hz, depending on the country's requirements, between
1500 and 1800 rpm. These generators will be started by the same mechanism
described previously. It is important to use a system with all the necessary
devices for each electric turbine. This will provide 100% electrical autonomy
to the aeronautical industry, and above all, flight autonomy, as stopovers will
be unnecessary, allowing for long journeys or even days-long stays in the
airspace of any location on the planet, enabling uninterrupted travel from one
end of the world to the other.
One advantage is that the aeronautical industry
is freed from the high cost of loading an aircraft with tons of fuel, and these
components, including two main and two emerging ones, most likely do not exceed
10 or 15 tons in weight, which suggests that aircraft will increase their
payload capacity to improve market competitiveness and customer satisfaction.
