Human effort has made many things possible with its intelligence and nature to do something. Every advancement happened in the history of mankind is to make the life of people easy. In the past, most of the industrial tasks were mechanical but then technology happened and the electrical machine took over almost everything. When we talk about the advancements, we’ve witnessed many innovations in the industrial field. The slip ring (Pancake slip ring) is one of those inventions that have made human’s life easy.
What is Pancake Slip Ring?
The Pancake Slip Ring is an electromechanical device used for the transmission of electric voltages from the static part of the machinery to the rotatory part. Didn’t get the definition? Don’t worry, we’re about to tell you complete detail about this amazing device.
There are some devices, in which we have to perform a specific task and that task can only be performed by the rotation of an object. So, we simply allow transmission of electric signals through a rotating assembly. That’s where we need the Pancake Slip Ring.
How does Pancake Slip Ring work?
A Pancake Slip Ring assembly is the same as a high voltage general slip ring having two basic parts, one is a stationary part that could be graphite or metallic brush and the other one is a rotating ring. The only difference is that pancake slip ring is platter and flat in dimension. The height of this type of slip ring is much lesser than the general slip ring.
The structure of pancake slip ring is not much complicated; the conduction material is attached on the surface of the flat plate and the metallic rings on the shaft. However, the weight and volume vary through different slip rings depending on the application and use. Mostly, precious metals are used to make contacts.
During the rotation, the stationary part (Metallic brush) transmits the electrical signals to that metallic ring. Hence, transmission of electric power occurs from stationary to the rotating part of the assembly.
Uses of the Pancake Slip Ring
Pancake Slip Ring is used in various electromechanical devices. This type of slip ring is applicable where height space is less, and the pancake slip ring has a minimum height. Some of its applications are:
Automobile Showrooms – This type of slip ring is used in the auto showrooms, where heavy mass is exhibited in a rotatory motion. Usually, vehicles are moved in a circular manner to show it to the customers. The pancake slip ring is behind that rotation.
Motors – This type of pcb slip ring is used in motors that are used in different type of motors. These heavy motors are being used in the cement industries.
Microwave Oven – One of its significant uses is in microwave ovens. The rotatory disc in ovens has pancake slip ring which rotates it.
Offshore Cranes – Mostly, these cranes have a combination of different types of slip rings in them. But the Pancake Slip Ring is also used in these types of cranes.
Necessary Precautions For Choosing a Pancake Slip Ring:
There are plenty of factors that you should keep in mind while purchasing a slip ring. Some of them are the following:
- If you’re planning to operate your Pancake Slip Ring in outdoor, make sure to go for a waterproof slip ring. It’s unfortunate that most engineers ignore this situation. Always specify your weather conditions to your company vendor so that he may give you the best slip ring according to your requirements.
- The slip rings used in mining or any operation where there are chances of the explosion of the device. Then, you must tell your vendor about the nature of your work. Always take necessary safety precautions while using Pancake Slip Ring in your devices.
- If you’re about to operate your device on heights, it’s a good practice to specify this to the company. It’s not that much crucial point, but still safety above all, always and forever.
- If your device requires more RPM, then go for the slip ring which suits your requirement. This will enhance the efficiency of your device. Most of the devices require less RPM, but on installing a slip ring of higher RPM, we’ve noticed the increase in efficiency.
Best Models Of Pancake Slip Rings
We’ve compiled a list of companies which manufacture high-quality slip rings. Their best models with their important features are given below:
Senring SNK Series – Their slip rings are best for limited height systems. SNK series pancake slip rings provide low-friction and low-resistance.
JINPAT LPK Series – These slip rings have a minimum thickness of 6mm, low noise, and high rotation speed. The best part is that you don’t have to worry about the connection drop. Their new technology eliminates connection drop scenario.
Moflon MP220 Series – These pancake slip rings have a thickness ranges from 18mm to 22mm, the structure is made up of aluminum alloy. The specialty of their slip rings is that the variation of resistance will be very low.
RotarX Pancake Slip Rings – The rotating speed of these slip rings up to 300rpm. Housing is made up of aluminum alloy and temperature ranges from -30°C to +80°C.
Asiantool Slip Rings – Their slip rings have very low noise and contact resistance. These slip rings are economical.
Always analyze the nature of your work. Be a good engineer, do some homework first then go out for your product selection so that you may not get in trouble during the operational work. We’ve seen people who do not pay attention to what they actually need and they end up having casualties.
