How to Calculate “Black Box System”
Mechanical to Electrical Conversion Generator Efficiency

How to Calculate “Black Box” Generator Efficiency
Mechanical to Electrical Conversion Efficiencies
Introduction:
An electric generator is a machine that converts mechanical drive shaft input power to
electrical output power.
At any operational No-Load, Steady State Speed or Rotational Equilibrium condition the drive
shaft’s Mechanical Input Power (Pin) to the generator is always 0.00 Watts because;
Mechanical Drive Shaft Input Power (P) = Net Torque(T) x System Rotational Speed(ω):
Pin = T x ω
Because T(net) = 0.00 at Rotational Equilibrium.
Mechanical Drive Shaft Input Power (Pin) on No-Load always equals 0.00 Watts.
When the generator is placed on load the drive shaft’s mechanical input power is provided by
the prime mover, which must always be increased (due to Generator Armature Reaction) in
order to deliver power to the load or the system will stall.
For example;
If the generator delivered 9 Watts to the load and the prime mover input increased by 10
Watts the “Black Box” System Efficiency would be:
Generator Conversion Efficiency = Output/Input x 100
9/10 x 100 = 90% Black Box Conversion Efficiency
If the generator delivered 5 Watts to the load and the prime mover input increased by 10
Watts the Black Box System Efficiency would be:
5/10 x 100 = 50% Conversion Efficiency
If the generator delivered 10 Watts to the load and the prime mover input increased by 10
Watts the Black Box System Efficiency would be:
10/10 x 100 = 100% Conversion Efficiency
If the generator delivered 10 Watts to the load and the prime mover input increased by 5
Watts the Black Box System Efficiency would be:
10/5 x 100 = 200% Conversion Efficiency

If the generator delivered 10 Watts to the load and the prime mover input increased by 2.5
Watts the Black Box System Efficiency would be:
10/2.5 x 100 = 400% Conversion Efficiency
If the generator delivered 10 Watts to the load and the prime mover input increased by 0
Watts (in other words did not increase at all or was reduced to below the no-load idle input
condition of 0 Watts), the Black Box System Efficiency would be:
10/0 x 100 = Infinite% Conversion Efficiency
ReGenX Generator Operating at Infinite Efficiency: https://youtu.be/pyO8FUTDX68
Demonstration Video:
The ReGenX Generator in the video demonstration is operating at infinite efficiency because
the prime mover power consumption does not increase when the ReGenX Generator is
placed on load from the no load rotational equilibrium level where the mechanical power in
the drive shaft is 0.00 Watts. (In fact the mechanical power in the drive shaft is reduced to a
level which is less than 0.00 Watts when placed on load).
If the prime mover's power consumption does not increase (or decreases) when the generator
is placed on load the mechanical power in the drive shaft on load remains at 0.00 Watts or is
reduced to less than 0.00 Watts.

Actual Generator Conversion Efficiency
The Actual Generator Conversion Efficiency would be the Prime Mover Input Increase (Watts)
x Prime Mover (induction motor) Electrical to Mechanical Conversion Efficiency (%) which
would be about 80% for the induction motor prime movers used and the speed of operation.
All of the tests in this document are operated at identical, torques and speeds and from an
initial operating no-load, Rotational Equilibrium condition where the mechanical input power is
always 0.00 Watts
What is Rotational Equilibrium?
The concept of rotational equilibrium is an equivalent to Newton’s 1ˢᵗ law for a rotational
system. An object which is not rotating remains not rotating unless acted on by an external
torque. Similarly, an object rotating at constant angular velocity remains rotating unless acted
on by an external torque. In this case it is the net torque which is important. If the net torque
on a rotatable object is zero then it will be in rotational equilibrium and not able to acquire
angular acceleration.

Analysis of ReGenX Generator Coil Load Current Delay

1) The conventional generator coil's Load Current Sine Wave is shown in green and the
ReGenX Generator Coil is shown in purple.
2) The conventional generator coil sine wave establishes the generator rotor magnet's
Physical Position with respect to the coil's core.
The conventional generator coil is employed to deliver electric power to the load and the
ReGenX Generator Coil is employed to allow the system to operate at infinite efficiency.
3) The ReGenX Generator Coil and conventional generator coil are wound on the same core,
they are influenced by the same changing rotor magnetic field in the same time domain and
they are connected to the same purely resistive loads (PF =1).
Voltage and Current are in phase with each other in both cases.
4) From position 1-2 we have a North Pole rotor magnet which is approaching the coils' core
and the conventional coil is inducing a North Pole electromagnetic field into the air gap
between the coils' core while the conventional coil delivers power to the load.
The conventional generator coil's induced (created) Magnetic Field Energy produces a
Counter Electromagnetic Torque on the rotor magnet which performs work resisting the rotor
magnet's approach and lowering the kinetic energy of the system.
According to the Work Energy Principle – the conventional generator coil's induced
electromagnetic field is a form of energy which is created because it performs work on the
rotor magnet when it reduces its kinetic energy.
Energy is the currency which is required to perform work in any direction.
The prime mover responds by consuming additional electric power and additional mechanical
power is delivered to the generator's drive shaft by the prime mover shaft until equilibrium is
reestablished.
5) From position 2-3 (after TDC) we have a North Pole rotor magnet which is moving away
the coils' core, the induced current in the coil has changed direction and the conventional coil
is now inducing South Pole electromagnetic field energy into the air gap between the coil's
core and the rotor magnet which produces a Counter Electromagnetic Torque on the rotor
magnet which performs work resisting the rotor magnet's departure away from the coil's core
and reducing the kinetic energy of the system.
According to the Work Energy Principle – the conventional generator coil's induced
electromagnetic field is a form of energy which is created because it performs work on the
rotor magnet when it reduces its kinetic energy.
The prime mover responds by consuming additional electric power and additional mechanical
energy is delivered to the generator's drive shaft until equilibrium is reestablished.
6) From position 7-5 we have a North Pole rotor magnet which is moving away from the coils'
core from TDC BUT the ReGenX Generator Coil's delayed Load Current is STILL inducing

North Pole electromagnetic field energy which produces a Complementary Electromagnetic
Torque on the North Pole rotor magnet as it is moving away from the coils' core at TDC and it
performs work assisting the rotor magnet's departure away from the coils' core (at TDC),
increasing the kinetic energy of the system.
According to the Work Energy Principle – the ReGenX Generator Coil's induced
electromagnetic field is a form of energy which is created because it performs work on the
rotor magnet when it increases its kinetic energy.
The electrical output power of the conventional generator coil delivered to the load coil is
increased due to Flux Harvesting, i.e. capturing of the created Electromagnetic Field Energy
from the ReGenX Generator Coil which is delivered to the conventional generator coil's core
in addition with the rotor's changing magnetic field.
Because the ReGenX Generator Coil's delayed induced electromagnetic field energy is
performing work accelerating the system, the prime mover responds by consuming reduced
electric power and a reduction of mechanical energy is delivered to the generator's drive shaft
until equilibrium is reestablished.
7) Also from position 7-5 we have a South Pole rotor magnet which is now approaching the
coils' core while the ReGenX Generator Coil's Load Current Delay is producing a North Pole
electromagnetically induced magnetic field energy which produces a Complementary
Electromagnetic Torque on the approaching South Pole rotor magnet and the ReGenX
Generator Coil's delayed induced magnetic field performs work assisting the South Pole rotor
magnet's approach to the coils' core.
According to the Work Energy Principle – the ReGenX Generator Coil's induced
electromagnetic field is a form of energy which is created because it performs work on the
rotor magnet when it increases its kinetic energy.
Because the ReGenX Generator Coil's delayed induced electromagnetic field energy is
performing work accelerating the system, the prime mover responds by consuming reduced
electric power and a reduction of mechanical energy is delivered to the generator's drive shaft
until equilibrium is reestablished.
8) Because the conventional generator coil's Counter Electromagnetically induced Torque
magnitude is LESS than the ReGenX Generator Coil's Complementary Electromagnetically
induced Torque, the NET TORQUE delivered by the two generator coils on the drive shaft is
POSITIVE which contributes to acceleration of the system.
The increase in the system's Kinetic Energy, with an increase in electrical output power
delivered by the conventional and ReGenX generator coils coupled with a reduction in the
power consumption of the prime mover and a reduction in the drive shaft torque and a
reduction in the drive shaft power delivered to the generator coils to a level which is below the
no load, Rotational Equilibrium level of 0.00 Nm and 0.00 Watts respectively ensures that the
system is operating at infinite efficiency.
