	Slip Rings
		Slip rings need continual maintenance to avoid degradation of the rotating electrical connection caused by normal wear and debris.
		Second, resistance through the rotating contact is less than one milliohm, which is much lower than the resistance of a slip ring.
		Fourth, slip rings require maintenance and Mercotac connectors are maintenance free.

	Slip Rings - Sibley
		Slip rings are supplied in a variety of sizes, number of tracks and current ratings and are custom made to meet the specific requirements of each application.
		The slip rings are the disk or "pancake" type typically ranging from two to 15 tracks and from one to 12 inches in diameter.
		Disk type slip rings are compact and usually are less than half an inch thick from the top of the brush block assembly to the bottom side of the slip ring.

	Slip Rings
		A slip ring is an electromechanical device that allows the transmission of power and electrical signals from a stationary to a rotating structure.
		Our large bore slip rings represent the union of new manu-facturing processes and technologies that enable us to offer large, mass-producible slip rings with advanced features, that are also cost effective.
		Slip rings are typically used in de-icing and blade-folding systems and main and tail rotors.

	Industrial Application: Slip Ring Testing
		Slip rings are basically circular, electrical “switches” and provide continuous signals and power to the rotating or revolving module, motor, or subassembly.
		Slip rings that generated voltage spikes exceeding the maximum allowable amplitude were returned for rework.
		Moreover, the procedure did not sufficiently characterize the true operation of slip rings nor guarantee their future performance because a waveform signature was impossible to obtain and store for subsequent evaluation.

	JQR 320.1 and 360.2 MG Sets and Slip Rings/Commutator Page 1
		Slip ring patterning is caused by cantilever vibration of the brush in the brush holder and can result from the following conditions: brush tension too low or too high, worn bearings, or rotor out of balance.
		Resurfacing is also required when slip rings contain deviations caused by excessive brush wear due to incorrect brush tension, worn bearings, or failure to change polarity of the brushes.
		Slip rings that do not resurface true, or that have imperfections too great to be removed inplace, will be delivered to the appropriate shop for lathe turning or slip ring replacement.

	Slip Ring Motors
		The slip ring or wound rotor motor is an induction machine where the rotor comprises a set of coils that are terminated in sliprings to which external impedances can be connected.
		The slip ring motor is used primarily to start a high inertia load or a load that requires a very high starting torque across the full speed range.
		Shorting the rings out on a slip ring motor with a high inertia load is not an option as the load energy must be dissipated in the rotor winding during start.

	Slip Rings
		The slip ring assembly comprises a spool, which rotates with the main body and fits snugly over the 3/8" IPT threaded pipe that serves as the "spine" for the payload, and a brush block mounted to a bearing housing which also supports the camera and compass platform.
		Each ring has a slot 0.025" wide and 0.05" deep cut into its inner surface to which are soldered #26 AWG bus wire stubs for connection to a #28-6 ribbon cable routed along the inner surface of the hollow ring-washer stack.
		After the ribbon cable conductors are soldered to their stubs, the rings and washers are pressed onto an acetyl tube 0.60" OD and 0.38" ID, having an axial groove 0.05" deep 0.30 wide on its outer surface to accommodate the thickness of the ribbon cable.

		Obviously the quality of the slip ring is a key determinant in the quality of the overall system.
		For continuous rotation of 360 ° slip rings or rotary joints are required.
		Besides contacting slip rings for the transfer of low data rates more and more non-contacting rotary joints are used, especially for the transmission of digital data at high bit rates.

	Variable Slip Generators for Wind Turbines
		As we learned on the previous page, the motor (or generator) slip in an asynchronous (induction) machine is usually very small for reasons of efficiency, so the rotational speed will vary with around 1 per cent between idle and full load.
		The slip, however is a function of the (DC) resistance (measured in ohms) in the rotor windings of the generator.
		If you have a variable slip generator, however, you may start increasing its slip once you are close to the rated power of the turbine.

		In this way, brushes and slip rings provide a connection between the armature coil and an external load which uses the power supplied by the generator.
		The slip rings and brushes are better suited to low power due to the special nature of the materials used.
		The field coil is wound on a soft iron core and, with a steady dc voltage applied to the slip rings, a steady electromagnetic field is produced.
