Product Description

Product Description

What is a conductive ring?

VS-RD series of conductive ring consists of conductive fiber, metal body and other components, applied to frequency conversion motor and its coupling equipment galvanic corrosion protection.VS-RD series of conductive ring can reduce the induced potential between the bearing and the grounded casing, effectively reduce the hazards of galvanic corrosion due to the axial current, to protect the motor bearings in order to protect the motor for long-lasting and stable operation.

Why use conductive rings?
Conductive rings are used for galvanic corrosion protection of inverter motors and their coupling equipment.VS-RD series of conductive rings can reduce the induced potential between the bearing and the grounded casing, effectively reduce the hazards of galvanic corrosion due to shaft currents, and protect the motor bearings to ensure the long and stable operation of the motor.

Features

With the rapid development of new energy vehicles, the electrical corrosion of bearings is becoming more and more serious under the conditions of high voltage, high frequency, high speed and high power of motors, which has become an urgent problem to be solved in all automotive industries.
VS-RD series conductive rings solve the problem of motor shaft electrical corrosion by bypass grounding.
It is composed of conductive fibers, metal bodies, etc., and is used for electrical corrosion protection of variable frequency motors and their coupling equipment. VS-RD series conductive rings can reduce the induced potential between the bearing and the grounded housing, effectively reduce the hazards such as electrical corrosion caused by shaft current, and protect the motor bearings to ensure long-term and stable operation of the motor.
