The trailing edges of the rotor blades are very thin and sharp. Exercise
caution when unpacking the blades to avoid injury. Fig. 7.4
Superwind rotor blades are manufactured as sets of three and are balanced by
weight and pitch deflection. The three blades can be fixed to the hub in any order,
however do not mix and match blades from different Superwind blade sets as this
could cause the rotor to become unbalanced. This means that if a single blade is
damaged, the entire set must be replaced.
7.4.1 Mounting of the wind vane
The wind vane is fastened to the rear cover
of the generator. Insert the wind vane and
the mounting plate into the groove. As
viewed from the rear (Fig. No. 7.4.1), the
mounting plate must be on the right side.
Next, insert the M8 x 20 socket cap screws
into the mounting plate and torque to 30nm
(22 ft lb). The screws have TUFLOK (blue
color) thread lock applied to prevent
loosening once installed and during
operation. Due to this coating, some
resistance during installation is normal.
Note: Check the tension of the socket cap screws M8 x 20 holding the mounting plate
and wind vane annually as part of the generator’s routine maintenance schedule.
7.5 Rotor assembly
There are two methods to that can be used to assemble the rotor of your Superwind:
a) The hub is mounted to
the generator shaft and
the rotor blades are
attached to the hub
afterwards.
b) The rotor blades are
attached to the hub first
and the assembled rotor
is then mounted to the
generator.
We recommend method “b” as it is easier in most cases to first assemble the rotor
completely at a convenient place, then mount the rotor to the generator.
