ITALTECH WIND is part of Italtech Group, the group that has been a world leader

in the construction of injection molding machines for the automotive sector since

1984 and which currently has over 300 employees with a network of support

centers located throughout the world.

Thanks to 25 years of experience in one of the more technologically advanced

sectors, such as the automotive, and by taking advantage of the synergy arising

from the construction of large-tonnage injection molding machines in this field, the

Italtech Group has been able to invest more than 3 million euro into Research and

Development in the wind-power industry in the last 3 years.



INNOVATIVE PATENTED MULTISTAGE PERMANENT

MAGNET GENERATOR

The generator is the result of the cooperation between ITALTECH WIND

and the Polytechnic of Milan - Electrical department.

ITALTECH WIND has the sole right to use the patent of the Polytechnic ofMilan:

«SYNCHRONOUS ELECTRICAL CONCENTRATED COIL MACHINE»

International Publication Number WO 03/103114 A1

MAGNET GENERATOR

www.italtechwind.it

FROM THE ELECTROMAGNETIC PRINCIPLE, ITALTECH WIND

DEVELOPED AN INNOVATIVE GENERTOR INTRODUCING NEW

CONCEPTS FOR:

INSULATION

COOLING

MANUFACTURING AND ASSEMBLING

ESPECIALLY FOR WIND ENERGY APPLICATION




MAGNET GENERATOR

www.italtechwind.it

THE NEW ELECTRICAL MACHINE IS SUITABLE FOR VARIOUS FIELD:

WIND ENERGY HYDROELECTRIC MARINE

AND OTHER FIELDS FOR THE VERSATILITY OF THE ELECTRICAL

MACHINE



GENERATOR MANUFACTURING CHARACTERISTIC

STATOR

Compact and concentrated coils structure,

winded around stator teeth

ROTOR

Multiple discs structure filled by permanent

magnets.

Bearings stack system, in order to facilitate

the generator assembling.

www.italtechwind.it



GENERATOR PERFORMANCE

Higher efficiency thanks to the absence of the field excitation

Higher winding factor and good electromotive force waveform

Absence of torque ripple

Absence of teeth harmonics

Absence of magnetic noise

Axial magnetic flux

Low operating temperatures

absence of forced ventilation

www.italtechwind.it



ITALTECH WIND presents the new IW200-35 direct drive

wind turbine provided by an innovative multistage

permanent magnet synchronous generator capable of 200

kW power.

www.italtechwind.it



ITALTECH WIND WIND TURBINE INNOVATION

The ITALTECH WIND wind turbines, unlikeconventional turbine generators, do not have a

gearbox: the turbine shaft is the same as that of

the generator .

This means that the production of electric energy

occurs at the same speed of the turbine.

www.italtechwind.it



DIRECT DRIVE

Benefits:

• mechanical friction reduction;

• noise reduction;

• number of machine components reduction.

www.italtechwind.it



HIGH PERFORMANCE AND ENERGY EFFICIENCY

Direct drive: low friction and the reduction of rotating parts

The absence of the excitation current

Extremely high performance generators even at partial

load

Blade designed “together” with the

generator and specially for the application

An advanced control system able to

handle the variable speeds and the

variation of the blade pitch

REDUCED MAINTENANCE AND RELIABILITY

ITALTECH WIND wind turbines are characterized by a reduced number

of extremely efficient components and are extremely reliable with

reduced maintenance and service needs

www.italtechwind.it



Thanks to these features, together with reduced maintenance

requirements, ITALTECH WIND wind turbines are able to offer

excellent energy efficiency, particularly in sites with low-intensity winds.
