4. 4 EC MOTORS Domel has been independently developing EC
motors since 1986. Over the years we have gained the knowledge and
expertise of key motor technologies (stamping and molding) and
enriched core R&D competences in electromagnetics,
aerodynamics, acous- tics, rotodynamics, power electronics, rapid
prototyping and testing. With all the in-house knowhow Domel is now
present in various markets where EC technology is becoming more and
more no- ticeable. Some of the applications where you can find
Domels EC motors are HVAC systems, gardening appliances, power
tools, au- tomotive components, white goods, vacuum cleaners,
fume/smoke extraction devices, boilers, handling devices, medical
and labora- tory equipment, and much more Increased awareness about
energy savings lead Domel to develop EC motors and controllers for
HVAC industry, which is one of the top leading users of electricity
consumption. In 2009 serial produc- tion of EC motors, named AZ
motors, was industrialized. When developing highly efficient AZ
motors, we placed consider- able emphasis on the optimum use of
materials, state-of-the-art technology and long-life operation. The
excellence of these mo- tors is further enhanced by their high
capacity and strongly wear- resistant housing, optimal coordination
between the motor and controller, and the monitoring of the rotor
position without Hall sen- sors. They require no maintenance since,
with the exception of the bearing system, they do not contain any
mechanical parts which are susceptible to wear and tear. The motors
are highly efficient (up to a level of approx. 95%) and have an
excellent power capability. It is worth adding that AZ motors are
extremely compact with very short bed length.
5. 5 ENVIRONMENTAL CARE In an era of rising energy prices,
concerns about reliance on gas, cli- mate changes and environmental
taxes, the awareness of the impor- tance of the environment and
energy saving has never been higher. Naturally, this trend is not
only driven by increased awareness about energy saving, but also as
a result of international political activities, which are becoming
increasingly stringent. Heating, ventilation and air conditioning
are among the five leading users of electricity consumption. Domel
followed the trend in con- tributing to energy savings and, in
2009, commenced with the serial production of EC motors
specifically designed for HVAC applications, named AZ motors. These
motors adhere to the regulations and direc- tives for motor
efficiency requirements and guarantee enormous en- ergy savings and
hence improved Return on Investment. The products exceed the IE4
Super Premium efficiency class and, in ac- cordance with the newly
proposed standard, also fulfill the criteria for the IE5 Ultra
Premium efficiency class (according to IEC 60034-30). When
purchasing a motor driven system, lifetime costs are of con-
siderable importance. To only compare purchase prices is a false
economy which overlooks the considerable financial benefits of the
lower operating costs that may be achieved with a more efficient
and quality system. Our motors reduce operating costs by working at
very high level of efficiency within a wide speed and power range.
Ad- vanced technology and state-of-the-art equipment assures
highest quality and long lifetime of the product with maintenance-
free operation. In comparison to standard AC motors in the IE2 High
efficiency class, annual production of Domels AZ motors
additionally saves more than 100 GWh of electricity each year,
which is comparable to the annual supply of a medium-sized hydro
power plant. In other words, Domel annually saves about 60.000 t
CO2 , which is equivalent to the average generated exhaust of a
vehicle traveling 300 million kilometers (source Europes Energy
Portal (www.energy.eu)). Source: standard IEC/EN 60034-30 Source:

Applications Motors can be used in: -- axial fans -- plug fans --
centrifugal fans (backward or forward curved blades) -- mixed flow
fans -- pumps -- compressors AZ MOTORS OVERVIEW EC motors type AZ
are electronically commutated, brushless DC, per- manent magnet
synchronous motors. They are available in four frame sizes: AZ 84,
AZ 108, AZ 150 and AZ 220. Motors come in two options with or
without additional cooling. Motors without additional cooling can
only be used in applications where the motor is mounted into the
airstream. For all other applications motor needs to be temperature
tested or additional cooling is needed. EC motors require a motor
controller and cannot be run directly off the mains AC power
supply. Torque 2 - 45 Nm / 1.5 - 33.2 Ft-Lb Efficiency up to 95 % -
