DYNETICS

Dynetics, founded in 1994 and with offices in Germany and the Netherlands, assists engineers in selecting the most suitable motor for their mechatronic assignment. Dyneticsrepresents leading manufacturers such as Nidec (Copal, Servo Etc.), KSS, Nippon Pulse Motor (NPM) and Elmo, Mellor, ETC. and offers a wide range of small rotating motors (up to 200 W) and highprecision linear motors (up to 100,000 N) with various technologies (piezo, brush, brushless, coreless), together with peripherals like ultra-high-precision lead screws, miniature ball screws, gearboxes, electronics and so on.Many of the motors supplied by Dynetics can be customised. Examples of such include a double shaft or modified shafts, encoders and different windings. All fans and motors can be fitted with connectors as per customer request.

Many of our fans and blowers can also be customized, e.g. with wire, plug, pulse generator, PWM connection for speed control, IP class protection, etc.

PortfolioThe products in the Dynetics portfolio can be roughlydivided into five groups:1. Rotating solutions in different technologies:

• stepping motors (PM or hybrid);• brush and brushless AC, and PMDC-motors (with or without gear head);• coreless motors;• piezo motors;• options like gearheads and encoders.

2. Linear solutions in different technologies:• linear servo motors (actuators, cylinders and stages);• Steppermotors (PM, Hybrid / Captive etc.)• precision lead screws and miniature ball screws.

3. Motion controllers (ASIC, PCB and box level).4. Fans and blowers.5. Customised solutions.

Logistics and serviceDynetics offers a comprehensive logistic system with a central warehouse in Best, the Netherlands, for optimal supply chain management. While the main focus is on the European market, Dynetics has customers around the world. As it understands that local presence is sometimes required, Dynetics also works with an extensive reseller network that is able to provide customers with the best possible service, as reflected in its motto: “Dynetics is a reliable partner with a long-term commitment focus”.

FANS & BLOWERS

Thank you for your interest in our products.

In this magazine we try to give you an overview of our possibilities.These are overall standard versions of fans, but because every application has its own specific cooling requirements we can help you select a product, ideal for your application and specified to the demands of your application.How you can calculate how to select a blower you can read in the first few pages of this brochure, but of course we are more than happy to select a fan for you.

Please contact us for more information.

Fan and blower selection

.1 Selecting a fan or blower

The required airflow and ventilating resistance of equipment must be determined when selecting a fan or a blower. However, accurate determination of a ventilating resistance is difficult. In general you can select a fan's max. airflow by multiplying the required airflow by 1.3 to 1.5. The following figure [Fig. 6] shows the case of an air channel with an area approximately equal to that of the fan. If an adequate air channel is not available due to a high density of mounted parts, a fan with a max. airflow of more than two times the required airflow is sometimes needed. In this case, a special fan for a high static pressure region or a blower is recommended.Dynetics would like to help you to determine the ventilation resistance of equipment exactly;If 3D data of the device is available, we can work with fan manufacturers to calculate the resistance.

Calculation of the required fan airflow

The airflow (ventilation rate) required for the internal cooling is calculated as follows:

Q ＝Ｗ

ρ×C × Ｔ

＝Ｗ

Q : Required airflow〔m3/s〕

W: Heat generation rate 〔W 〕

ρ: Specific weight of air〔kg / m3〕

C : Specific heat of air 〔J / kg°C〕

Performance degradation of PQ characteristics when options are installed

Options such as a fan guard and filter are sometimes installed for safety.These options, however, increase the ventilation resistance and noise. A fanguard has slight ventilation resistance and degrades the PQ characteristicsonly negligibly. However, when tightly fitted onto a fan, the noise levelincreases by about +1 to +5 dB. In particularly, options should be installedmore than 10 mm away from the fan to minimize the increase in noise.Using a □120 mm×38 mm AC fan (CN55B3) as an example, fluctuationsof the PQ characteristics when options are installed are plotted in Figs. 12and 13.

Super silent multiblade blowers (radial fans) realize cooling to the point More pressure and airflow at axial type of fans

Fans with many options

the unit that request a cooling becomes smaller by the day and request an increase of performance and efficiency .To follow such trend in efficiency at the cooling of such a unit request a high qualified type of fan with either a high static pressure or a compact or a compact and super silent multiblade blower.Dynetics offers for the cooling of electric- or electronic-equipment a new family of axial- and radial fans from market leaders of suppliers.

On customer request we can integrate extra intelligence into the fan.Our DC type of fans and blowers can be expended with for instance an alarm functions that respond in case that a difference in the speed occur. Fans with this alarm function and assembled in a system will help to switch off the equipment in time at the moment that the fan is starting to show problems. This will extend the lifetime of the unit.An integrated speed control, and managed by a PWM input (Pulse With Modulation) enables the equipment to fine tune the speed according the momentary demand; resulting in a reduction of the power consumption and of noise. This speed control option is showing his advantages when for instance the equipment is in a sleeping status.

DC Micro blowers

Our Micro Blowers are innovative ultra-small high-power products which integrate aerodynamic bearings. Furthermore, because of the non-contact state during rotation, astoundingly resulting in less vibration, and long life due to no dependence on temperature. The line-up of Micro Blower is total of 5 types. Of these, three types are able to purchase the Kit with driver.

Micro Blowers with Aero-dynamic bearings

These new Micro Blowers use our patented Aero-dynamic Bearings technology.

This revolutionary technology utilizes the effect of air pressure between the motor shaft and sleeve to provide a contactless rotational motion.

The Aero-dynamic Bearings technology allows us to manufacture high-performance, and compact Micro Blowers. Our product lineup currently has 5 different types. We also provide motor drivers to customers who are looking to do preliminary testing or Proof-of-Concept.
