FlatTracking Sun Solar Slewing Drive With 24V Stepper Motor And
Encoders For Solar Trackers
Tracking Sun Solar Slewing Drive
The sun tracking slewing drive is a core part in turning the
oblique single-axis tracking system which is a cost-effective
product mainly developed and designed for the construction of
large-scale power stations, and is widely used in middle and low
latitudes.
The system only needs the entire array can be automatically tracked
by using a set of slewing drive and controller. The unique linkage
structure and maintenance-free slewing drive can make it reliable
and reliable system stability, low failure rate and low maintenance
costs. Compared with the traditional fixed installation bracket, it
can increase the annual power generation by about 30%, which is a
large-scale power generation system.
Ideal for station construction.
Key Features
1. An unlimited rotating angle and range
2. Provide the most efficient transmission of high power and torque
possible
3. Completely enclosed and sealed housing withstands harsh
environments and increases safety

Applications
Flat oblique single
"Flat oblique single", or "flat uniaxial with inclination" is the
product of the combination of the above two modes. In fact, the
flat inclined single should belong to the category of the flat
single axis, its rotation axis is horizontal, and his entire
tracking system can follow the flat single axis system. The
difference is that each component on its axis of rotation has a
certain inclination to the south.
Inclined single axis:
The inclined uniaxial has a certain inclination to the south, so
this situation is better than the flat uniaxial. But the oblique
uniaxial also has its own limitations. Due to the inclination to
the south, the inclined uniaxial support becomes higher and higher
from the ground on the north side as the rotation axis grows, and
because the rear column cannot be made too high, the rotation axis
of the inclined uniaxial is limited. It cannot be made into a long
shaft as long as a single shaft, but can only be independent one by
one, which increases its cost and, of course, increases the floor
space.
Flat Single Axis
The flat uniaxial tracking bracket can significantly increase the
power generation by tracking the sun's trajectory in the east-west
direction, but the flat uniaxial also has its disadvantages.
Because the flat uniaxial support has no inclination to the south,
its radiation receiving ability is poor when the sun altitude angle
is low, which is especially obvious in high latitudes. There has
been a decrease, especially in winter, and the power generation is
even lower than that of fixed mounts.
