What is a contactor coil?
a contactor is generally looks like a small box connected to an electric circuit. it is what controls electricity flow to a motor. in the middle is normally a way to push in the contactor to manually check to see if either the motor works or if you have electricity.
How to choose rating of contactor in star delta starter?
As well as motors, contactors also have kW and Ampere ratings. Have a look on the name plate of your motor and you will see its maximum current draw (amps). Select a contactor with a current rating greater than this.
How do you select contactor for motor?
With a contactor we can control the power connection to the motor (power on/off). A typical AC contactor comes with 4 terminals aside (L1,L2,L3,A). 'A' has A1,A2 terminals which are of the magnetizing coil. By magnetizing & demagnetizing A1-A2 coil, power line connections to motor can either be made or broken. This is a simple DOL (Direct On Line) application. Further, reverse/forward circuits and star-delta circuits can be constructed based on the requirement. A contactor's role in whatever application is 'making or breaking' the contact. The coil supply can either be AC or DC.
Which is good demand among ece and mechanical engineering?
let look from the different angle, mechanical engineering and ece has almost equal scope but mechanical have little higher because mechanical has wide variety of subjects and every skilled mechanical engineer has got statisfyed job.... now we look from ece,ece is the easy to learn and has good job outlook,every professsionaly skilled engineerhas good job aspect...

Are bionicles robots?
Although in the movies they look like robots, they are NOT robots, they are bio-mechanical, meaning they are like cyborgs, like 20% mechanical. They most likely look robotic due to their armor.

What does Velcro look like under a microscope?
Under a microscope, Velcro appears as a mechanical fastening system with tiny hooked loops on one side and a corresponding looped surface on the other side. The hooks and loops interlock when pressed together, providing a secure fastening mechanism.
What is the difference between jersey and interlock fabric?
hi in jersy one side look line and another side is purl, mostly we used for t shirt and interlock is both side ribbed, like single jersy line. and in rib one drop needle used

Why does the air conditioning compressor keep operating long after the system is turned off?
The contactor on the outdoor unit is probably stuck. Disconnect the power to the indoor unit, then disconnect the power to the outdoor unit and take a look at the contactor.

A mechanical thing on a track in the middle often designed to look like a rabbit.

What does an interlock monitor switch do in a microwave oven?
In general, the interlock monitor switch in a microwave oven is the switch that shorts the line out (knocking out the internal fuse) in a microwave oven if the door interlock switch stays shut when the door is opened. The interlock monitor switch is the monitor for the door interlock switch. Let's look at things more closely and see what that means.The door interlock switch opens when the door opens, and this prevents the oven from coming on when the door is not shut. That way no one gets zapped. Simple. The door interlock monitor switch will close when the door opens, but this switch closes after the door interlock switch opens. The interlock monitor switch does nothing if everything is working properly.In the case of a door interlock switch that has suffered an arc and the contacts become welded shut, that switch will remain shut when the door is opened. This might allow the oven to run with the door open. But if this happens, the interlock monitor switch, which will shut when the door opens, will short the line if the door interlock switch remains closed when the door opens. This will knock out the line fuse and "kill" the unit. If any microwave oven presents with a blown line fuse, one of the mandatory checks must be the door interlock switch and the door interlock monitor switch.

What is interlock fabric how it is knitted?
Interlock fabric is a variation of rib knit construction. Similar to a Jersey knit except both front and back of the fabric look identical. Double knit construction makes this a thicker knit fabric. Interlock is the tightest weave, gives the smoothest surface and the finest hand. The fabric is extremely soft, firm and absorbent.
