Factors to Consider When Purchasing an Air Compressor Electric Motor

Just like when purchasing any other tool for your workshop, you must consider some specific factors before purchasing an air compressor electric motor. If anything, not every seller in the market today has your best interests at heart as their customer. Some are in the business with a goal of making money at whatever cost. Also, a product might be of high quality but may still not suit your type of work or air compressor. To minimize the chances of suffering from any type of disappointment, consider the factors below before signing up for anything:


The power of the electric motor is something that you should not compromise on. In fact, if you fail in picking a motor with enough powering for your tasks, you will not handle any of them successfully. Today, it is possible that you can find 3 HP and 5 HP air compressor electric motors. The latest invention has seen to it that 7.5 HP air compressor electric motors are also available. picking a 5 HP motor that supports anything between 208 and 230 volts will see to it that you handle most of your tasks with utmost ease. These motors have enough powering to glide through any task.


The rule of the thumb here is simple; the bigger the size of your motor, the better the quality of the services you will receive. However, it is always important to by the motor size that is stipulated by the manufacturer of your air compressor. in the same spirit, compatibility is another factor that you need to put to consideration. Also, it is important to note that motors of smaller sizes are lighter and easier to install as compared to the bigger ones.

The Speed of Operation

The maximum speed under which your electric motor can operate is also another factor to consider. In most cases, the speed of operation of a motor is measured in RPM. A higher RPM indicates that the motor can operate at a top speed thereby improving its efficiency. On the other hand, a lower RPM indicates that the motor is slower. It also goes without saying that motors with higher RPMs are more expensive as compared with those that have lower ratings.

 In that case, if you are not keen on handling huge tasks with your air compressor, settles for an electric motor of an average RPM. We suggest that you settle for one with 1750 RPM if you are going to deal with lighter duties. However, if you are going to use your air compressor to handle heavy duties occasionally, opt for a motor of 3430 RPM. If you have no idea as to which one is the right one for you, consult your dealer or look for information online.


The brand of the motor also plays a part when determining the right air compressor electric motor for you. Today, different brands are available with all fighting to gain as many customers as possible. However, not all of these brands sell quality products. If anything, some of the products sold have the best specifications and are sold at affordable prices.

However, most of the motors break down as soon as they are installed thereby putting you through extra costs. When out to purchase a motor, consider a reputable brand, one that has been there for a considerable amount of time. Also, make sure that the brand of motor that you are about to buy is similar/compatible with the air compressor that you own.


While it is true that a motor is a very useful part in an air compressor, it is also true that you do not have to spend a fortune to acquire one. Most dealers are available today. Take your time to identify a cheaper and reliable one. If you have no clue where to look, simply look for information online by keying in the right keywords. From here, you will get reviews of the best dealers with the best prices. Settle for one that has the product that you are looking for and offers genuine services.


There is absolutely no point in purchasing a motor that will break down after a month. In that case, it is worth the trouble to take your time in picking one with the best construction and strength. Motors with steel frame constructions are the best. Also, look out for additional features such as the presence of ball bearings, copper windings and quality fans all of which play a huge role in boosting the durability of the motor.

Final Word

Finding the best air compressor electric motor is not as hard a task as many people purport. If anything, all you have to do is figure out which motor is compatible/suitable for your air compressor and you are good to go.
