Introduction to AMarkWIND
2
The AMarkVAWT group has been established in 2016, and now, based on
our business model and targets, we are going to continue our business in
Denmark starting 2021. The AMarkWIND is a new brand for wind turbines
with an optimized design from electrical, mechanical, and economical point
of view. In AMarkWIND, different geometries of wind turbines have been
studied and the advantages and disadvantages to each of them have been
used to design the innovative AMark rotor. Besides, high performance and
compatible PM Generator and Electronic Controller and Monitoring System
have been designed for AMarkWIND products. AMarkWIND would produce
renewable electricity with more reliability, efficiency and safety. Currently our
small-scale products suitable for householders and small business are ready
to get necessary certifications and enter the market.

Vertical Wind turbines Horizontal Wind turbines
Pros:
› Optimized and industrialized design
› High aerodynamic efficiency
› Variable blade pitch, which gives the turbine blades the optimum angle of attack
Cons:
› Essential need to have a Yaw mechanism
› High weight to swept area ratio due to larger stress on blades
› Creating noise due to high rotor rotational speed
› Rain-drop erosion due to high blade-tip speed
› Technical issues in construction of rotor larger than 10 megawatts
› More bird death because of perpendicularity of their path to the direction of
rotating blades
Horizontal vs. Vertical design
Pros:
› Omni-directional
› Low weight to swept area ratio and possibility to reduce the production cost
› The possibility of constructing a rotor larger than 10 megawatts
› Stability of tower due to rotation of rotor about tower axis
› Lower noise and rain-drop erosion* due to low rotational speed
› Lower Floater cost for off-shore applications*
Cons:
› Aerodynamic efficiency lose due to struts
› Lower rotor rotational speed results using low-speed generator
› Variety of geometries and not industrialized design
› Vibration due to oscillation of torque produced by each blade

Introduction to AMarkWIND
In the AMarkWIND the blades have been twisted mechanically (or
aerodynamically) in order to optimize the Angle-of-Attack along the
blades regarding its V-shaped design.
Blade Design*
In the AMarkWIND the Swept Area of rotor have optimized by
choosing the best inclination angle of blades for different strut
and blade lengths. The rotor is a V-Shaped VAWT.
6
Strut Design*
In VAWTs, a considerable amount of power is being wasted
because of the struts. In the AMarkWIND project, a prevailing
and innovative configuration have been designed for the
structure and airfoil of Struts.
Blade Support
In AMarkWIND rotor design the Blade Supports have been added in
order to reduce the stresses on blades. As a result, the weight of the
blades was reduced to one third, meanwhile, the CFRP material has
been replaced with GFRP.
The design of Pitch Control Mechanism for AMarkWIND is
simple, efficient and reliable. Universal joint, gearbox and
servomotor are the main components of this innovative
mechanism for a V-shaped utility scale VAWTs.
Electronic Control Design
In AMarkWIND project, an advanced Electronic Control System have
been designed. This unit has a Modular, Distributed and Scalable
architecture, and it is going to control and optimize the performance
of turbine using Artificial Intelligence (AI) and Machine Learning.

Patent Certifications
Introduction to AMarkWIND
AMarkWIND products have lower price in comparison to other
products thanks to its integrated, innovative and revolutionary
design, specially in large scale products.

Birds-Friendly
Since the AMarkWIND products are Vertical Axis Wind Turbines,
Birds could notice the rotor more easier. In HAWTs birds could
not foresee the blades coming from above because of
perpendicularity of their path to the direction of rotating blades.
Affordable and Economic
High Performance
The Blades, Struts, Pitch Controller, Generator and Electronic Control
Unit have been designed in particular for AMarkWIND; All the main
components are compatible with each other.
Durable and Safe
Thanks to supports, the Active Pitch Control Mechanism in Large-scale
products, and Intelligent Electronic Control Unit, our products would
withstand severe hurricanes. Also these products would produce power
in larger wind speed range.
Smart and Intelligent
We have employed efficient Machine Learning algorithms to optimize
the performance of our products in different conditions continuously.
Advantages of AMarkWIND Products
Harmonious and Silence
Rotating vertically, is delightful. AMarkWIND is a VAWT with
V-Shaped rotor design, and it has lower noise in comparison
to the conventional HAWTs.

Roadblocks on the way of installing more Small Wind Turbines
• Small wind turbines are Not Economic for householders considering their Price
• Most of turbines in the market are Not Looking Fancy and Harmonic
• Some brands make Noise
• Some people do not Trust on the performance and power output of the turbine
• Maintenance Costs are High in lots of brands

Competitive price
AMarkWIND is designed to reduce the costs of wind energy.
We used our talents and knowledge to design a complete
product with competitive price, since it is the master key in
this business.
Sustainable Growth
Our business model would lead to a sustainable growth rate
using high-performance management strategies. For instance
we will invest our income to add large-scale products.
Risk Free Sales Method
We are going to sale our small-scale products using pre-ordering and
leasing methods to reduce risk of investments. Using Bank supports as
partners is our solution for selling our products using leasing method.
Win-win Agreement
We will make our costumers to feel Wining by buying AMarkWIND
products. The AMarkWIND-5KW is an ideal choice for householders to
generate clean electricity for their home and also their EVs. The
costumers would pay the turbine’s price in six or seven years, and their
annual payments would approximately be equal to their previous
energy bills. After that, costumers would enjoy almost free energy.
We have designed the Rotor, Generator, Power Controller,
Grid-tied Inverter and Tower based on the aerodynamic
performance of our Rotor. This strategy leads to compatibility
of AMarkWIND products.
Direct and Indirect Jobs
Jobs related to the Production, Installation and After Sale Services
would provide several direct and indirect careers.

Wind Potential in Denmark
Ref: https://globalwindatlas.info/
Based on the GlobalWindAtlas.info
almost all regions except Copenhagen
in Denmark has average wind speed
over 7 m/s in 50 meters height from
the surface, and this shows the
significant wind energy availability.
