Car 2 speed fan wiring

I want to know the fundementals behind 2 speed control in the motor. Will it be applicable for slip-ring motors also? It is very helpful thanks. Hi guys. Please explain to me if I must really put a contactor on my 3 phase motor. And can I not just run it straight without a contactor. You need a contactor for controls.

A three phase motor had Star Delta written on the name plate but could not work in 2 speeds star-delta.

It was correctly connected. What could be the problem? How to combine boltages from two DC dynamo wheels and supply them outside. Kindly email me the diagrams for star deltor and direct online for a 3speed 1directon 3ph motor, have two of them in a Bow Cutter.

One contactor burnt for high speed and a replced contactor does not engange, originally the coils re fed with a nutural and the one i replaced is only working with a phase. Thank you. Here use 3 contact Why here low speed during time 2 contact energy k1,k2 and high speed running time k2 Only one And why we use low speed time star winding High speed time with out Star winding Say something about it as soon as possible.

And what is the logic behind the low and high speed.

Dual electric fans could be the solution to your cooling issues. Dual electric cooling fans have several benefits over single fans — Dual fans can pull or push more CFM between the two fans versus a single fan, and dual fan setups allow for more clearance for front of engine accessories. There are several ways that a dual fan can be wired. For example, dual thermostat switches or dual relays could be used to control each fan separately.

Or a single relay could be used to control both fans. Start your wiring project by taking both of the positive wires from the fans and run them to the yellow wires on each relay tab Then connect switched power usually from your ignition switchto the blue wires on both relays tab Next, splice together both black wires from the relays tab 85 and connect them to the thermostat switch.

Finally, run a fused constant power to both of the red wires on the relays tab With dual electric cooling fans wired as shown, you can keep your engine cool, and in most cases, not have to worry about clearance issues between the radiator and grill. Follow Us on Flipboard. DIY Projects.

It used to be that electric radiator fans were low-performance add-ons that maybe pulled a couple of extra degrees of heat out of overheated muscle cars.

But today, they are an integrated part of all but the most heavy-duty vehicles. There are hundreds of electric radiator fans available in the boneyard in a variety of sizes, many of which are dictated by space considerations.

These fans move a serious amount of air, which is why they are so popular with car builders. The hero is obviously the inch, big-dog Lincoln fan, which is still relatively easy to find in the boneyards. Most of these electric radiator fans operate in two speed modes—high or low—depending on coolant temperature.

Some however, are only capable of a single speed. A three-pin connector indicates a two-speed version.

The electric fans with only two wires in the connector are the less desirable single-speed units. Wiring is the area in which some car crafters may need some help. Rather than simply toggling these electric fans on and off in high-speed mode, there is a simple and easy way to wire the fan to operate it in both modes, running the high speed only when necessary.

This is especially important when you consider that the fan's high-speed side demands every bit of the 40 to 42 amps to keep it spinning. This places significant load on the charging system. Low-speed operation pulls a more conservative 28 amps.

Because each vehicle application is different and car crafters are good at mounting the electric fans, we focused our attention on the critical aspect of wiring and establishing an efficient switching mechanism.

While you can just hook up a simple toggle switch, that's troglodyte tech. We can do so much better.

Both Delta Current Control and Spal make excellent pulse-width-modulated PWM fan controllers that can ramp fan speed much like factory computer controllers. These controllers are a great way to emulate new-car cooling technology in your muscle car, and the controllers are fairly reasonable.

The best version of this system is the three-relay kit that comes with two temperature sensors. The low-speed sensor triggers the fan at degrees F, while the second sensor engages the high-speed side of the fan at degrees F. All three relays are ganged together for easy mounting. We can't emphasize enough the importance of a high-output alternator to supply the amperage necessary to spin this fan.

Plan on using a amp output alternator to ensure there's plenty of power for all your muscle car's electrical devices. We covered high-output alternators in the Sept. Close Ad. Jeff Smith writer. Share on Facebook Share on Twitter.We show you how to wire in an electric fan relay kit with a thermostatic switch. If you've got an electric cooling fan on your classic car or hot rod and you want to know how to wire it with a relay, you've come to the right place.

While you could just wire the electric fan to run all the time, hooking it up with an electric fan relay kit that is temperature controlled—or to use the fancy term for it, thermostatically controlled—is a much better idea.

Our example for today's "how to" lesson is MotorTrend tech center technician Christian Arriero's Plymouth Duster. Christian picked up a Painless Performance electric fan relay kit with a thermostatic switch from Speedway Motors to control the electric cooling fan on his Duster. The temperature-controlled switch is designed to turn the fan on when coolant temperatures reach degrees and turn off the fan when temps drop to degrees.

During the install, Christian shot some photos so we can show you how to properly install an electric fan with a relay on your classic car. Install the temperature-controlled sending unit in one of the cooling passage ports on your intake manifold, making sure to use a high-temperature thread sealant to prevent leaks. The sending unit has two male spade connectors, one of which will go to the black wire on the relay, and the other needs to go to a ground.

It's wise to use a star washer to ensure a good ground. This is especially true if, like our application, your grounding location has a protective coating over the metal. The positive wire coming from the electric fan will connect to one of two red wires on your relay while the negative wire needs to go to ground. If you are unsure which wire is which coming out of the electric fan, find the fan manufacturer's supplied wiring diagram.

If you're still not sure, once you've completed all the wiring, let the car warm up to temperature, and once the fan kicks on you will be able to feel if it is pulling air from the front of the car.

If it's not, turn the car off, swap the two wires, and you should be good to go. Where to mount the relay is up to you, and Painless Performance supplies a self-tapping screw with which to secure it. It is best to find an area that will be largely free of significant moisture within the engine bay or—if you want to hide the wiring—within the inner fender well. While you might be tempted to just run the positive wire from your relay directly to the positive terminal on the battery, that is a big no-no.

You either need the constant volt power to be run through a circuit breaker or a fuse. In the Painless Performance electric fan relay kit we got from Speedway Motors, a circuit breaker is supplied if you wanted to safely get power directly from the battery.As many of you know, clearance between the front of your engine and radiator can be very tight.

Dual electric fans could be the solution to your cooling issues. Dual electric fans have several benefits, like being able to pull more cfm between the two fans versus having just one fan, also allowing more clearance for front engine accessories. There are several ways that a dual fan can be wired. For example, dual thermostat switches or dual relays could be used to control each fan separately.

Or a single relay could be used to control both fans. Other methods that I have used to wire up dual fans are using single relays to control both fans. I have found this to be inefficient as most dual fans pull enough load in amps at start up to blow the fuse for the relay. This should be around a 30 amp fuse in order to protect the wiring and relay.

I have also used dual thermostatic switches that control each fan individually. This method also requires more wiring and dual relays. It can also be beneficial in certain circumstances but usually is unnecessary, as most of the time you only want your fans on to cool the car down then to have them shut off.

For this set up we also used two of the Speedway Universal Electric Radiator Cooling Fanpart numberwhich comes in a 10, 12, 14, or 16 inch diameter. The color coded diagram below will correspond with the wires on the relay kit to help simplify the wiring process.

Start with taking both of the positive wires from the fans and run it to the yellow wires on each relay. You will then need switched power usually from your ignition switch, wired to the blue wires on the relays. Next, both of the black wires from the relay can be spliced together and ran to your thermostat switch. Lastly, run a fused constant power to both of the red wires on the relays.

With these dual fans wired up you can keep your car cool and not have to worry about clearance issues! Help is just a click away! Products to Compare max of 3 X. Videos All Videos. More Info. Related Articles.

It shows the components of the circuit as simplified shapes, and the capacity and signal associates amid the devices. A wiring diagram usually gives information nearly the relative slant and understanding of devices and terminals upon the devices, to incite in building or servicing the device.

A pictorial diagram would appear in more detail of the creature appearance, whereas a wiring diagram uses a more figurative notation to highlight interconnections greater than being appearance. A wiring diagram is often used to troubleshoot problems and to create sure that every the associates have been made and that anything is present. Architectural wiring diagrams act out the approximate locations and interconnections of receptacles, lighting, and remaining electrical facilities in a building.

Interconnecting wire routes may be shown approximately, where particular receptacles or fixtures must be on a common circuit.

Wiring diagrams use adequate symbols for wiring devices, usually vary from those used on schematic diagrams. The electrical symbols not abandoned deed where something is to be installed, but moreover what type of device is mammal installed.

For example, a surface ceiling lighthearted is shown by one symbol, a recessed ceiling lighthearted has a alternative symbol, and a surface fluorescent open has another symbol. Each type of switch has a alternative fable and in view of that do the various outlets.

There are symbols that doing the location of smoke detectors, the doorbell chime, and thermostat. A set of wiring diagrams may be required by the electrical inspection authority to assume link of the quarters to the public electrical supply system. Wiring diagrams will then count up panel schedules for circuit breaker panelboards, and riser diagrams for special services such as flame alarm or closed circuit television or supplementary special services.
