Product Description

The span cable must be allowed to swivel at the pivot, otherwise it would be wrap itself around the pivot. The device which allows the cable to rotate is called a collector ring.
The collector ring consists of brass rings in a stack that remain stationary and are separated by insulators. Contact brushes revolve around the brass rings providing continuous flow of current without twisting the cable as the machine makes revolutions around the field.
The electrical control calbe is then fed from the collector ring through a pipe which is J-shaped and exist the riser near the top of the riser. The control cable is then routed down the pivot leg along the pivot brace, and into the main control panel.

Mounts on a stainless steel J-Pipe above the upper elbow to
minimize water contact.
Sealed to prevent water and dust contamination inside.
Positioning the collector ring above the upper elbow ensures that
the brushes are always aligned with the slip rings - no side forces.
Small diameter means less brush wear and longer trouble-free life.
Easy to replace / repair, if needed. Electronic positioning resolver is positively attached and protected
from the elements.
Mechanical controls are easy to adjust.
The same collector ring is used on all pivot points from 6 5/8"
through 10".
The collector ring transfers the incoming 480-volt power to the rotating spans. The 480-volt power is supplied to nonrotating copper rings (one for each conductor). Brushes (one for each conductor) rotate with the spans. The brushes transfer the 480-volt power from the copper rings to the span wire.

Features and Advantages
1.The collector ring outer cover of irrigation sprinkler uses engineer plastic,improve the function of impact resistance, weather resistance, UV resistance.
2.The base uses aluminum die cast,guarrantee the hardness ,and more portable . 
3.precious metal inside for collective power,life time for 80,000,000times rotation,stability for signal trasmission.
4.Rotor and stator as integrated style, no need for maintenance
5.Encoder and collector ring are integrated structure,optimize the structure design.
6.more precise and control the moving angle of each span
7.All materials have been treatment by anti corrosion.keep stable operation in harsh climatic conditions.higher protection degree .double protection degree .
to ensure the products perform satisfactorily in rain and snow .

Installion Way
The collector ring install on the center of rotation device ,consist of rotating and stationary. The rotating parts connect on the rotating structure and rotating , called as "rotor".the stationary parts connect on the fixed structure,called as "stator"."rotor"connect on base side thread hole G1 or G1/2 ."stator" connect on the bottom base installation axis G1 .

Maintenance Mode
Not exceed the rated current and voltage.This product rotation of 5-10 minutes with no-load and then plus load .So as not to affect the electrical properties

A series of synchronous motors and asynchronous motors, which are widely used in the industrial sector, and most of which operate under various harsh conditions, are widely used in the industrial sector.
