The Influencing Factor of Safe and Stable Opreation of Slip Ring and Electrical Brush

1.The Ventilation and Cooling of Electrical Slip Ring and Brush

The main reason why electrical brush and slip ring operate heating energy.Acute friction makes brush cause vibrate in a operating process,makes noise,generates heating energy and result in unstable contact,even makes brush broken.the more number there is brush,the bigger ratio is friction,and the greater damage is friction.Therefore,its especially important of ventilation and cooling matter of generator slip ring,brush.

2. Selection of electrical brush

The quality of brush generator mainly lies on its material.The good or bad material impact on life of brush directly.Different models,different manufactors products,different material and abrasive resistence.Good material impact on dynamic and static contact surface of slip ring and brush,and increse friction pressure of slip ring.Soft material makes brush damage easily,and change frequently,the powder generated by friction attach to surface of slip ring,it has a impact on electrical conduction performance.Therefore,should choose mature electrical brush.

3. The adjustment of Electrical Brush Spring pressure

The operation of comtact pressure of carbon brush and slip ring provided by constant pressure,every constant pressure spring whether uniform or not has a impact on distribution of every brush current density.

4. Regularly Maintenance and clean

When generator units are operating,slip ring and carbon needs to be cleaning regularly to avoid to generate the carbon powder attach to slip ring due to friction of brush and slip ring,result in a unhealth phenomena between slip ring and carbon brush.

LPS-12B- Stator

Separate Slip Ring


This unit can be used in any electromechanical system that requires unrestrained, continuous rotation while transferring power or data from a stationary to a rotating structure.

It is also called a rotary electrical interface, commutator, collector, swivel or an electrical rotary joint. It can improve electromechanically capability, simplify system design, eliminate possible damage while rotation. It’s the key apparatus of various precision rotary worktable, electric test instrument, manufacture and process control instrument.

The LPS-12 separate slip ring is a standard, off-the-shelf unit that uses gold contacts at the rotary interface. Color-coded lead wires are used on both the stator and rotor for simplifying electrical connections.

Using a 90° V-groove ring design for each ring, the LPS-12 provides smoother running, lower torque and lower electrical noise than competitive slip rings.
