State the terms associated with contactor starter used for starting and stopping induction motor some term and definition about contactors?
voltage, current, resistance, horsepower, contacts, overloads, coil, terminations, NEMA, IEC, NFPA 70 NEC, motor controls, NFPA70E . . . A contactor is a double make/break per phase switch that opens and closes the circuit to the motor by energizing a coil (electro-magnet) using a motor control circuit (usually, but not always a lower voltage than the motor circuit). The motor control circuit goes through a normally closed set of contacts that will open if the overloads that are in series with the motor circuit sense too much current going to the motor.
Describe a double pole single throw relay with a 24 V coil And how does it work?
Double pole single throw relay de-energized, with two separate sets of contacts open. Apply 24 volts to coil terminals, coil steel core magnetizes and pulls hinged armature towards it. The two contacts attached to hinged armature make contact with the two stationary contacts. The double pole relay has now two separate sets of closed contacts.
Which direction does a motor spin?
All motors have the ability to rotate in either direction. The motor has to be connected to additional equipment to make this happen. In a three phase motor a reversing magnetic contactor is used and in single phase motor usually a drum switch is used.
What is the purpose of a coil spring?
A coil spring works by compressing and then expanding when a vehicle is going over pumps. Coil springs help make the ride a little smoother for most vehicles. The coils spring is attached to the undercarriage.
What features make Maglev trains economical?
to make it go faster the wheel support path will help it and the propulsuion coil will help it
What causes an electrical contactor to make a buzzing noise when activated and what should be done about it?
Contactor chatter can be caused by a broken shading ring winding on the pole face of the contactor. Low voltage to the coil can be another reason for contactor chatter. A constant hum on a contactor will be caused by misalignment to the two pole faces. Check for rust building up on the two surfaces.
Split unit air conditioner outside unit not running. Inside comes on - air blows not cold - outside unit buzzes?
the buzzing is probably your contactor. there are two 18 gauge wires going to your contactor coil the two wires will follow your line set out of your house and into AC to the contactor coil. usually red and white. or blue and yellow. make sure you have 24 volts with your volt meter (T-stat must be calling for cool). make sure you have 240 volts going into line side of contactor(L1 L2). there should be a run capacitor or two. usually a silver duel capacitor it will be round. is it mushroomed at the top? do you have voltage on both sides of contactor and 24 volts to contactor coil when thermostat is calling for cool?. and no voltage at capacitor or it looks mushroomed, you have a bad capacitor. the best way to test one is with a mircrofared tester. less then10 bucks to replace it will have a number ie. 35/5 uf if it is a duel. make sure you get the same one. if you don't have 24 volts to contactor coil or if contactor isn't pulled in. your problem is in the t-stat or funace. if you don't have 240 volts going into line side of contactor you have a tripped breaker or blowen fuse somewhere, or high pressure cutout needs to be reset due to dirty condenser.(usually only on Rheems) if you have 240 at line side L1 L2 and 24 to the contact coil but no 240 on T1 T2 of contactor you have a bad contactor which i would replace anyways since it sounds like it's buzzing. they are about 10 bucks too. let me know if this helped I'm pretty sure it's your capacitor. the capacitor if it's a duel will have three different terminal circles. C, fan, and Herm. C is for common it goes to the common wire on the contactor either a red or yellow wire. fan uses the wire coming from the fan and herm uses the wire coming from the compressor.
How many 1 square centimeters make 1 square meter?
10000 square centimeters make up a single square meter.
Can you cut a square in a single straight line and make a pentagon?
Yes by cutting a corner the square will then have 5 sides
When do you replace a contactor?
With the power off! Once you replace it make sure all your connections are tight!
How do you wire a contactor 20 amp?
A contactor is nothing more than a switch but it is electrically operated instead of mechanically operated as you would find with snap switches in your home. As with any switch, you need to make sure it is rated for the voltage and amps you intend to feed through it. You will have a pair if terminals for each hot wire. In addition you have terminals for the coil that operates the contactor. Very often this is a smaller voltage but not always. These control wires may be connected to any piece of control equipment, which may be a snap switch, but may also be a thermostat, light or motion sensor, or various types of hydraulic sensors such as pressure, flow, or float. In today's technology the coil may be activated by computer signal which may be reading many different conditions.
How do you make the word coil into a noun?
The word coil already is a noun, as in "a coil of rope."
How many channels do you need to power my subwoofer?
mono or two channel are the best for subs but it depends on if your sub is dual voice coil or single voice coil, what ohm load the amp can handle, and if it is single voice coil and are using one sub you need to make sure you can bridge a 2-channel amp if that's the kind you chose... Next question you ask it may help to add a bit more detail. If I knew the sub brand and model, ohms, and if it's dual or single voice coil i could help answer that much better.
Can a silver coil make a magnetic field?
It is the flow of ELECTRICITY that makes the field in a coil. Therefore a coil of any conductor will make a field. Silver is a conductor.
How do you change a ignition coil on a Chevy Caprice?
It depends on what year it is. 74 and older have a bottle style coil mounted to the intake to the driver's side of the distributor. 75-86 have the coil mounted in top of the distributor cap (make sure you replace the coil with the correct coil. If it has a white wire, it must be replaced with a white wire coil. If it is a yellow wire, it must be replaced with a yellow wire coil). 87-95 uses a square coil mounted to the intake and has two wire conntectors and the coil wire. LT-1 motors use a crank trigger ignition system that has a different coil system altogether. I don't have information on this system.
What is the most electricity you can make with a magnet coil?
A coil doesn't make electricity it can however alter voltage and amperage output.
