The DS-30-DIA 3-ph - Highest performance and efficiency for the 69mm
class
The DS-30-DIA 3-ph is the answer to the fast development of batteries and motors in the past
few years. The DS-30-DIA 3-ph is designed for the highest power input and can handle rotational speeds up to 50.000
rpm.
The development of the DS-30-DIA 3-ph is a result of all research and experience we have made with carbon
fibre EDF's since 1994.
The concept is based on the DS-51-DIA 3ph. The main features like the diagonal rotor
design and the fluid mechanical calculation are equivalent to its big brother.
All parts of this fan are made
of carbon fibre in CNC machined molds. The production of all parts is made in our own workshop in Germany which guarantees
the highest quality level.
The DS-30-DIA 3-ph reaches its high efficiency due to the optimum combination of
number of blades, blade depth, airfoil and thickness distribution. The rotor is exactly matched with the
stator.
Most 69mm fans suffer from heavy vibrations and resonances at higher rpm's. This is caused by a
resonance which occurs because of the thin 1/8" shafts in combination with too long and too heavy rotors. The DS-30-DIA 3-ph
has a very lightweight and short rotor which is fine balanced, you will be amazed about the smooth operation even at 45.000
rpm.
All parts can be used directly from the box, the rotor is fine balanced and assembled. Stator,
motorformer and shroud are one complete unit, there is no extra work than installing the motor.
