1. Century SVB2054 Flat Shaft Evaporative Cooler Motor

Century Evaporative Cooler Motor

View on Amazon

The very first swamp cooler motor we would like to give you information on is the Century SVB2054 flat shaft evaporative cooler motor.

It is one of the most powerful and popular swamp cooler motors because of its highly efficient performance and cooling mechanism.

For someone who wants to run their swamp coolers for hours without damaging the integrity of their motor is really going to be thrilled with this choice.

Century is one of the top names that come to our minds whenever we think about investing in a high-end motor for a cooler.

The brand takes pride in manufacturing high-quality products that come backed with incredible warranties.

The overall performance of this bad boy is epic. With premium construction quality and a solid cooling system, the motor can last for up to 10-years or more.

Century is so confident about their products that they have even backed it up by a 10-year warranty.

During this time period, if anytime you feel the motor is malfunctioning, you can always have it replaced without paying any extra money.

High Efficiency

When it comes to swamp coolers, what we need most is high efficiency from the motors when they run.

If your motor isn’t performing well, doesn’t have a good RPM and the torque isn’t sufficient, then your cooler will collapse sooner than you expect.

This is where the Century SVB2054 evaporative motor comes into play. It has 1725/1140RPM and runs at 1.6HP.

The torque is enough for swamp coolers whereas the RPM is ideal for small coolers. We won’t expect this motor to work well with heavy-duty motors though. You will have to look for better torque in that case.

Construction Quality

The next thing in line is obviously the construction quality. No cooler motor can ever be reviewed thoroughly if we don’t talk about the manufacturing aspect.

It’s imperative that you go over the construction quality of the motor you’re probably going to buy over and over again. If you find even the slightest glitch, don’t buy that motor at all.

The Century SVB2054 is built out of the highest quality alloy and can easily resist high temperatures. The brand has also given a 10-year warranty where the construction quality is concerned.

If any time you fear the motor might be malfunctioning, get in touch with the manufacturer ASAP.

Incredible Cooling System

This is an air compressor motor that comes with multiple heat dissipation holes. It allows the motor to quickly release heat even when it’s running so the motor never heats up.

We really appreciate this feature of the Century SVB2054 motor because it enhances the overall lifespan of the unit.

Final Verdict:

The Century SVB2054 cooler motor is a commendable choice for its enigmatic build quality and great performance efficiency. If you’re in search of a high-end motor, go for this one. You won’t find anything better.

Pros
  • Runs smooth and quiet
  • Great performance efficiency
  • Commendable cooling system
  • Easy to install
Cons
  • Shorter dimensions

This is why even our previous recommendation can have a cooling mechanism and so does this one.

The Dial has integrated this motor with thermal overload which provides optimal protection against overheating.

Anytime, the motor crosses its determined threshold for heat, the thermal overload will kick in and cool it down. This way, your motor will continue to work and you won’t have to switch it off to give it a rest.

Solid Construction

The next thing to consider is obviously the construction quality. We all know the durability of a product makes or breaks the purchase.

The Dial has infused the stainless steel motor with corrosion-resistant capabilities to enhance its overall lifespan. Even after years of use, it is guaranteed the motor will not get rusty even to the slightest.

It can clearly resist moisture without getting damaged and the lifespan will remain intact.

The guide will give you all the information you need to integrate the motor without spending any extra bucks.

Construction Quality

Best Swamp Cooler Motor Buyer’s Guide:

Now that you have taken a look at all the product recommendations above, we have some more information for you to make a more informed decision.

Finding the best ½ hp swamp cooler motor takes a lot of time and effort. You need to keep a number of things in mind if you want to end up with the right model for your swamp cooler.

So, taking the entire conversation forward, we are going to discuss a number of factors that you must keep in perspective when shopping for an evaporative cooler motor.

Things to Consider When Buying a Swamp Cooler Motor:

Voltage

The very first thing you will have to consider is the voltage. Do you have an electric outlet through which you will get all the power you need?

Or you are going to go for a wireless motor that runs on batteries.

When it comes to finding a motor for coolers, we recommend going for a 115volts motor because it offers a sufficient amount of energy that will be able to power up your motor efficiently.

It gives all the energy you need and you will not have to rely on batteries as a power source.

Frequency

Next, you need to consider the frequency of the motor. Most of the motors in the United States run at 60Hz. However, if you’re buying a motor outside of the US then you will probably need a frequency below 60Hz.

It’s completely up to what kind of cooler you will have the motor installed. You can always check the owner’s manual to get all the information you need.

Speed

Ask yourself, if there is a speed or a certain set of speeds that you need to run your motor on? if there is then try and search for the speed set you need.

We are sure you’re going to find a number of motors that will provide you what you’re looking for.

Also, when it comes to swamp cooler motors, there are also models available that offer dual-speed settings. These motors are extremely functional and give you a lot of options to customize your entire experience.

Power

Don’t think that the amount of power your motor offers is equal to the amount of power your appliance consumes. Both of these things are different.

Sometimes, people end up buying motors that offer more power than their appliances actually need.

Those kinds of motors are actually more expensive and you pay for the power that you’re probably never going to use.

This is where you need to do all your research and then go ahead and make a purchase.

Cooling Mechanism

Is your appliance going to be running continuously or will it have small intervals in which the motor will get time to cool off?

If you’re planning to run your cooler for consistent hours, then you must go for a motor that has integrated the unit with a cooling mechanism.

This way, it won’t need small intervals to cool off and won’t heat up at the same time.

But, if you’re planning to use the cooler in small intervals then go for a motor that comes at an affordable price. It may not have a cooling mechanism but it will do all the things you need.

Life Cycle

How long do you need your motor to last? Appliances that are run intermittently can mostly get by even with motors that don’t have a longer lifespan.

But, if you’re appliance has to run consistently on high power as a swamp cooler does then you need a motor with a longer lifespan.

There are several models, even among the ones we have recommended above that you can choose from. These motors last long and offer a great level of performance efficiency.

Construction Quality

Of course, we cannot deny how absolutely necessary it is to consider the construction quality. When it comes to motor manufacturing standards, never compromise.

The lifespan of your motor is going to be determined by how solidly built the unit really is. Make sure it is corrosion and rust-resistant.

Swamp cooler motors are exposed to moisture consistently so they are more prone to rust. Having a water resistant-motor is going to be your best call here.
