How expensive is an electric motor?When the motor of your air conditioning unit is having problems and must be replaced, looking for surplus electric motors for sale can be a terrific idea. Buying discounted new motors or used electric motors at competitive prices will help you save money.
Plus, when you compare it to the potential cost of buying a new AC system, replacing the motor is often a better bet for many people’s budget if all the other parts of the system are still operating well.
Additionally, while electric motors are commonly used in HVAC, they have many applications in different industries. They’re often used in manufacturing, automotive, and renewable energy since they can power assembly lines, packaging equipment, compressors, and electric or hybrid cars. So, looking for affordable surplus options can make a big difference in many circumstances.
Different Types of Electric Motors for Air Conditioners
There are several types of electric motors you might see in AC units. The type of motor you need will depend on the type of AC unit you have in your home, so it’s important to be able to distinguish between them to ensure you buy the right one.
- Shaded-pole motors: You’ll find these most often in window ACs. They don’t have as much power, so they can’t run large units and aren’t as energy efficient. That said, they’re simple and cost-effective when you’re on a budget.
- Permanent split capacitor (PSC) motors: These are usually found in full central air conditioning systems designed to power entire homes or large spaces. They’re widely used in air conditioners since they’re known for their reliability and efficiency.
- Electrically commutated motors (ECM): These are usually used in ductless mini-split ACs. One of the benefits of these motors is they can operate at different speeds to adjust airflow and cooling capacity as needed. It also makes them very energy-efficient since you can turn the speed down when you don’t need it.
- Split-phase motors: You’ll find these in packaged AC units. Packaged ACs have all the components in one outdoor unit, so they need a powerful motor to operate the fans and compressors to effectively cool your space. Split-phase motors provide enough starting torque to do so.
- Direct current (DC) motors: You might see these in some AC units, such as ductless split ACs or inverter window ACs. DC motors have a greater range of speeds but are more sensitive to load weight or volume changes. You might also see them used in electric or hybrid cars.
Benefits of Using Surplus Motors
Using surplus motors can be a game-changer for businesses looking to cut costs without compromising on quality. One of the most significant advantages is the cost savings; surplus motors are typically 30% or less expensive than new motors. This makes them an attractive option for businesses aiming to reduce expenses while maintaining operational efficiency in industrial settings.

Another key benefit is the quick availability of surplus motors. Unlike new motors, which may take months to build and deliver, surplus motors can often be customized and obtained within days. This rapid turnaround can significantly reduce downtime and boost productivity in various industrial applications.
Surplus motors also offer a high degree of compatibility. They can be an exact or extremely close match to the motor being replaced, both electrically and mechanically. This compatibility eliminates the need for costly modifications or upgrades, making the replacement process smoother and more efficient. Additionally, many surplus motors come with warranties that match or even exceed those of new builds, providing businesses with peace of mind and assurance of quality.
Are Old Electric Motors Worth Anything?
When your old electric motor stops working or starts to wear down, you might still wonder if it would be worth anything if you were to sell it.
The answer is yes. They can be worth something, especially if they contain valuable materials like aluminum or copper or are still functional and can be resold. Therefore, selling them can be a good idea when looking at electric motors for sale since it can help offset some of the cost of buying your new one.
Factors Affecting the Value of Old Electric Motors
Here are some common factors that affect the value of your old electric motor to help you determine how much it might be worth:
- Material composition: As mentioned, even if your motor isn’t functional, it can still have value if it contains the right materials. Specifically, if it has copper windings or aluminum, both of those have high scrap value. The specific amount of metal content and ease of separating the metals will determine how much you’ll get for it.
- Condition: When your motor still works, it will naturally have more value if you sell it. Used motors are often bought for industrial HVAC systems or other applications. To estimate its value, you should look for noticeable damage and test the motor’s operational capacity under load.
- Size and type: Larger motors with more horsepower will contain more metal and be worth more when scrapped. The type of motor (such as AC vs. DC) can also impact value depending on its value in different markets. For instance, DC motors are more valuable in systems that require precise speed control.
Who Bought GE Electric Motors?
General Electric (GE) has undergone significant changes in the last decade, including selling various divisions. In 2018, GE's small industrial motors division was sold to Wolong Electric, a Chinese electric motor manufacturer, for $160 million.
The sale included the design, development, manufacturing, and sales of low-voltage TEFC (totally enclosed fan-cooled) medium-voltage motors, marking a major shift in GE’s manufacturing operations.
GE's primary reason for making changes like this is the company wants to focus more on its core businesses, which include aviation, healthcare, and energy. GE showcased this shift in focus when it split into three companies: GE Aerospace, GE HealthCare, and GE Vernova.
Are Electric Motors Still Sold Under the GE Name?
After the sale to Wolong Electric, GE-branded small industrial motors continue to be manufactured and sold by Wolong under the GE name. Therefore, while they’re still labeled as GE commercial motors, it’s important to understand it’s a different company making them now.
Is the Quality Still Comparable for These New Motors?
So far, the quality of these motors seems to have remained similar. However, as HVAC systems and home appliances advance, it’ll remain to be seen if Wolong Electric will continue to adapt and thrive in the industry as GE has in the past.
That said, other manufacturers like ABB, Siemens, and Regal Beloit also produce comparable electric motors, so you’ll still have many other options to choose from when looking for surplus electric motors.
How Long Can An Electric Motor Run Continuously?
Many electric motors are designed to run continuously, especially in HVAC systems, which are meant to constantly keep your home or business space at the desired temperature.
To ensure yours is good for continuous use, make sure you purchase electric motors labeled as type S1, meaning they are graded for continuous running duty. Most experts estimate that S1 motors have a lifespan of about 30,000 to 40,000 hours as long as they’re well-maintained.
Other motors labeled S2, S3, S4, or S7 are only meant for short-term or intermittent duty. It’s usually recommended to run these motors for 4 hours or less before giving them a break.
That said, when you’re looking at surplus AC motors or surplus DC motors for HVAC systems, they’re generally all S1 motors, so this isn’t a big worry.
What Is the Life Expectancy of the Electric Car Motor?
When researching surplus electric motors for cars or considering buying electric or hybrid cars with them, it’s common to wonder if it’s a worthwhile investment. Fortunately, you’ll be happy to know that well-maintained electric vehicle motors last quite a long time and generally last longer than internal combustion engines in standard cars.
Electric vehicle motors (such as DC motors) typically last 15 to 20 years. For the average person, that translates to around 300,000 driving miles. On the other hand, cars with internal combustion engines typically only last for around 150,000 to 200,000 miles under optimal conditions. Therefore, electric vehicles have a lot more longevity.
The main reason for this increased lifespan is that electric car motors are much less complex and have fewer moving parts, so they’re easier to maintain and often have fewer issues. Internal combustion engines require regular oil changes, filter replacements, and other routine maintenance that electric motors simply don’t need.
Maintenance Practices to Extend Electric Car Motor Lifespans
While electric car motors need less maintenance, you should still do some things to ensure they last as long as possible, such as:
- Monitoring cooling systems: Monitor your motor’s cooling system to ensure it’s functioning properly and to prevent overheating, which will degrade the motor over time.
- Protect against environmental factors: Keep the motor clean and free of dust or moisture. Avoid keeping it outside in extreme temperatures for extended periods of time. Parking your vehicle in a garage will help with this.
- Regular inspection: Get your vehicle inspected annually. During inspection, mechanics will check things like your cooling system and ensure the motor is clean. Additionally, they can often identify and diagnose signs of wear and tear, vibrations, or unusual noises. Fixing these early will prevent more severe damage that degrades the motor.
