*PARMANET MAGNET MOVING       COIL RELAY*


~The design of this type of relay is similar to that of PMMC type induction.

 ~ The torque generated is proportional to the product of the current passing through the flux and the coil.  

~Ta The pole piece of the permanent magnet is held together with the core. 

~ In between the iron is kept cylindrical so that the reflection of the magnetic field decreases as well as the magnetic field becomes radial.  

~The coil is wrapped on an aluminum formwork and the formwork is placed in the air gap. 

~The spindle is supported on a well bearing by placing it on the spindle. 

~ There are two spiral-shaped control springs attached to the spiral.  

~One is placed at the top of the fire and the other at the bottom.  

~The string acts as a controlling talk and carries current through the coil.  

~There is a moving contact on the spindle.  

~Torque is generated by the interaction of a magnetic field and current when current is passed through a coil.  

~Controlling torque is obtained by spring.  The coil deflates and the contact closes. 

~ This type of relay d.c.  Runs on and is kind of directional.  

~Using a rectifier, it is connected to the A.C.  Can be run on  Characteristic can be changed by adjusting the control spring. 

~The time setting can be changed by changing the position of the contact on the spindle.  

~The time-current factorial  movement of the coil in another type of moving coil relay is real cop like the coil of a windpicker.


~The coil is wrapped around the bobbin. 

~ Axial movement on the bobbin core is kept in contact.  

~When the current from the coil is applied in the right direction the force on the coil moves to the right hence the contact close.  

~This type of relay is more sensitive and delic than a deflecting coil type relay.
