Slip Ring

A vital component wherever there are rotating parts, slip rings use a brush contact assembly to pass current between static and moving parts, between stator and rotator. Slip rings are used in a wide variety of installations where rotating parts have a range of movement that prevents the use of a cabled connection – everything from vehicle turrets to wind turbines.

MK Test systems are used to test Dynamic Resistance of the contacts throughout rotation, resistance Noise throughout rotation, and high voltage isolation between rings. Test results are delivered automatically and include scope traces of dynamic resistance and noise.

Our oscilloscope module is integrated onto our system measurement bus, meaning you have access to the scope via every test point. A 512 test point system, effectively has 512 scope channels. MK systems are available with up to 524 thousand test points.

A vital component wherever there are rotating parts, slip rings use a brush assembly to pass current between static and moving items. Slip rings are used in a wide variety of installations where rotating parts have a range of movement that prevents the use of a cabled connection – everything from vehicle turrets to wind turbines.

MK Test equipment can test slip ring performance before final assembly into the destination vehicle or manufactured item, and will test connectivity through a range of movement, giving a readout from the test programme that ensures components can be passed as exceeding the design specification.
