Coin Vacuum Motors

Motors are the heart of your coin vac, providing the significant suction power that customers expect for effective cleaning. If you’re experiencing suction loss or your vacuum isn’t turning on at all, the motors are one of the first spots you should look when troubleshooting. By replacing motors, you’ll save a significant amount of money versus buying new vacuum units. You’ll probably be surprised at the relatively low cost and installation time needed to get your coin vacuums back to full performance.

When shopping replacement motors, a good starting point is to first determine how many motors are used in your unit, as well as the diameter of each one so your new ones will fit properly. Then, figure out the wattage, voltage, and horsepower of them. Other relevant specifications include water lift (sealed suction), airflow rating (cfm), and revolutions per minute (RPM). If your current motors are the original ones, you can defer to the specs listed on the sticker/plate when finding replacements. If you have your vac manual or data sheet, always consult those documents to be completely sure you’re getting the correct new motors.

Not only will weak suction result in customers ending their cleaning session quicker and reducing their spend, there’s a good chance you’ll see poor reviews and customer complaints about poor performance.

How to Choose the Correct Replacement Vacuum Motor:

Below is a list of important specifications to know before you order a new motor for your commercial car wash vacuum. You will want to match these specifications to the original motor to ensure a proper fit and reliable performance.

Important Vac Motor Specifications:

Motor Power: Expressed in Watts, kW, or HP, and depends on the type and number of motors in the vacuum.
Voltage: A measure of electrical energy, denoted in Volts. Most car wash vacuum motors operate at 120 volts and 240 volts. Some motors have uncommon voltage specifications that are vacuum-specific.
Motor Amps: The motor amps specification represents the total electrical current drawn by the vacuum, including the motor and other electrical components.
Water Lift (Sealed Suction): This metric measures the vacuum motor's strength and is derived from determining how many inches a vacuum motor will vertically lift a 1'' column of water. This test simulates the process of lifting dirt and debris from carpets.
Airflow Rating (CFM): Airflow rating, expressed in cubic feet per minute (CFM), is the rate at which air flows through the vacuum. The faster the airflow, the more effective the vacuum is at picking up dirt and debris.
RPM (Revolutions Per Minute): This specification tells you the maximum number of times the rotor can spin per minute. Speed plays a significant role in a vacuum cleaner's cleaning efficiency, particularly on carpets and other surfaces that require agitation. The speed of the motor varies drastically depending on the vacuum.
Diameter/Footprint: This is a measurement of a motor’s footprint using its diameter. Choose a motor with the same diameter as the original to prevent air from leaking. Air leaks negatively impact the vacuum's suction and the customer experience.

Frequently Asked Questions:

What is a VAC motor?

Vacuum motors are the heart of any vacuum cleaner. They’re the driving force behind the suction that captures dirt, dust, and debris during vacuum operation. Without a functioning VAC motor, a vacuum cleaner would be ineffective in performing its primary task. We carry motors designed to handle rigorous cleaning jobs in commercial and industrial environments, such as car washes and auto body shops. Given their role, they must be highly reliable and durable. These industrial vacuum motors are built using components that can withstand regular, heavy use, ensuring that cleaning operations are seamless and efficient. Understanding the specifications of a motor, including its power, voltage, and other key specs, is crucial for maintaining optimal performance and minimizing downtime in commercial settings.

How do I know if my vacuum motor is bad?

If you suspect your vacuum motor is malfunctioning, there are a few telltale signs. First, listen for unusual noises such as grinding or excessive humming, which may indicate wear or internal damage. A noticeable drop in suction power often signals that the motor is not operating at peak efficiency. You might also notice the vacuum overheating or emitting a burning smell, both problems suggest serious motor issues that need immediate attention. If you're experiencing frequent motor shut-offs, it could mean the motor is struggling to cope with its power demands. Regularly checking for these signs will help you identify motor problems early, ensuring your vacuum remains efficient and reliable for all cleaning tasks.

What causes a vacuum motor to burn out?

Vacuum motors can burn out for several reasons, impacting the efficiency and longevity of your cleaning equipment. One common cause is overheating, which occurs when the motor works harder than usual, often due to blockages in the system. These blockages can restrict airflow, forcing the motor to operate at higher than normal temperatures. Additionally, running the vacuum for extended periods without breaks can contribute to overheating, as the motor does not have time to cool down. A damaged or faulty bearing can also lead to a burned-out motor, as it causes increased friction and stress on the motor parts. This additional mechanical stress can wear down the motor components, leading to failure. Moreover, electrical issues such as power surges or poor wiring can cause an unexpected spike in the electrical current, which stresses the motor's internal components. Regular maintenance and monitoring can help prevent these issues, extending the motor's lifespan and ensuring uninterrupted cleaning operations.
