There is a question that everybody focus on it that how the motor works. Have you ever realize what that component is present in the motor that allows it to rotate? Then you can take a step back and recall the functioning of a motor. The motor is a perfect blend of individual components which are correctly assembled over and allow proper functioning of it.
Well, everyone knows that each of the elements has its role. So, here we are assigning to offer high-end output where some of the essential things to be offered a required level of resistance.
A slip ring is considered to be a part of this arrangement whose primary function is to allow 360 degrees incessant rotation to motor. This slip usually rings some energy in order to allow constant rotation of the respective assembly. When it comes to engine, this energy is mainly called as electrical energy. In order to gather essential details, then you can even follow here.
Essential parts of electromechanical devices
Slip rings are a very important part of electromechanical devices such as DC generator, AC generator, etc. The size as well as design of the motor usually depends upon the engine in whichit is going to use. The most of the common slip rings are used in the automobiles are through pneumatic slip ring, pancake slip ring, wireless slip ring, bore slip rings, wire slip ring and much more. Slip rings are used for transferring the data as well as power from stationary sources in order towards the rotating one.
We are here going to describe to you about the Slip Ring Motor in detail so that you can get aware of the various aspects related to it.
Why are slip rings being used in the motor?
An electric slip ring is mainly said to be electromechanical device that allows the motor for transmitting the electrical as well as power signals from the stationary device towards therotating one. Well, it is considered to be the main component of electromechanical engine that permits the system in order to rotate continuously without limitations.
The essential design of the slip ring depends upon the application where it is going to be used. For information, slip rings are found in different names when it comes to the market; electrical swivels, rotary electrical joints and then collector rings which all are said to be the shared names that mainly utilizing for electrical slip ring.
If we are handling over the usage of slip ring intended for data transmission, we need to have slip ring by means of higher bandwidth and improved electromagnetic interferences but if we are going to use it for power transmission, the aspects changes slightly. Whatever is the application you are going to use slip rings in, whatever be the size of the motor where it is going to be used,the essential components, i.e., rotating ring and stationary brushes remains the same. If we talk about the complete slip ring assembly it includes bearings, rings and end caps.
Usage of Slip Ring in AC Motors
AC Motor can be assumed to be the most beautiful examples of slip ring usage. We all know that slip rings are being used in the motor to allow rotations, but if we talk about AC Motors, the concept here is entirely different. Slip rings are mainly used here for inserting resistance to the rotor windings. Now, what’s that rotor windings?
AC induction motor is considered to be wound rotor motor and hence the winding being included here are rotor windings. If we discuss related to construction of an AC Motor, it includes three slip rings. All the slip rings being included here are made up of copper or copper allow to wear higher temperatures and to conduct electricity successfully. All the three slip rings in the AC Motor are usually mounted over the motor shaft.
Every slip ring includes with the composition here are being connected to the three different phases of the rotor windings. Slip ring brushes are commonly made up of graphite and linked to a resistive device for offering controlled performance.
How does the Slip Rings in AC motor works?
The slip rings are wounded over the AC motor. Whenever we switched on the power button, the engine starts running. It takes some time for the motor to reach the operating speed, and once it achieves, the brushes involved in the composition are being lifted above with the help of slip rings. The slip rings get now out of the circuit to allow the seamless working of motor.
Slip rings put in resistance to the rotor windings that helps in taking up the rotor and stator current more aligned. Higher torque is then produced along with the low current. Slip rings in the AC generator are used in the startup phase of the AC motor working. Once it attains operating speed, these get short-circuited and the brushes start to lose control over the engine.
Difference between the slip ring and commutator
Due to the functioning of the slip ring in AC motor, it is somewhere assumed to be much similar to the commutator. There are a lot of similarities between a slip ring and a commutator, but still, there are a lot of differences in both as well.
A slip ring is a continuous ring that offers ongoing transmission of signal, power and datathrough it. But if we start to discuss mainly about the commutator, it is usually segmented and is being used in the DC motors more commonly to reverse the polarity of the current.
Conclusion
Slip rings are always said to be the main crucial components of every electromagnetic motor that presents continuous rotation to it. The slip ring usually attached to a rotating end on one side whereas to the stationary end to the other side in order to provide reliable performing. If we talk about the applications, they are just numerous from amusement parks to automated welders, from wind turbines to medical imaging machines there are a lot of applications that the slip ring are being used.
Slip rings are usually used for transmitting data, signals, and electricity to the stationary portion to the rotating one. The design and the size of the slip ring often vary in applications in which is going to be used in. Rather than the traditional functioning, slip rings inside the AC Motors that creates resistance rather than offering rotation.
