The drive motor of the machine is usually found at the rear of the basket, and is either a belt driven or direct drive. As the manufacturers wish to suspend the basket from only two springs, they need to balance the weight of the motor at the rear of the basket. This is achieved by placing large cement weights at certain locations on the basket such that the weight of the motor on the rear is balanced about the two mounting points for the springs. In some cases, the total amount of weight can exceed 60 lbs., and accounts for a good percentage of the total weight of the machine. In addition to balancing the weight of the motor, the additional weight lowers the natural frequency of the machine and increases the vibration performance as the machine spins at very high speeds.

These components allow the machine to operate at any of its desired speeds, while minimizing vibration across the entire speed range.

The answer to this question is relatively straightforward in that there are certain features that we look for in a new washing machine. Vibration control architecture for washing machines has improved dramatically over the last several years, with several new technologies introduced. Prior to 2007, the internal design of washing machines had converged across several manufacturers to a more or less consistent design where four dampers and two springs are used to suspend the basket inside of the machine (often called a “six point suspension”). This design was found consistently in most major brands of washing machines and at the time was the most effective configuration. Most of these manufacturers advertised their machines as having advanced vibration reduction inside the machine, but these were little more than tweaks to the computer programs that controlled the machine and were, in our experience, only mildly effective.

Around 2007, one major manufacturer introduced the inertial ball balance ring vibration control, which consists of two concentric tracks at the front and rear of the basket that contain a viscous fluid and several ball bearings. By spinning the basket at the appropriate speed for a short period of time, the ball bearings would arrange themselves in the track opposite the imbalance in the basket, thus reducing the overall vibration experienced by the user. This means of isolating the vibration reduced the overall vibration generated by the machine by roughly 30% over earlier models in our estimation, and, in our opinion, represents the best commercially available means of internal washing machine vibration control. Using the same technology found in its ØVIB Washer Stand, Seicon Limited has created prototype washing machines that will outperform these machines by at least 50%. These machines, however, are not yet available on the market.

Additionally, some manufacturers are placing accelerometers (or ‘inertia sensors’) inside of the machine to measure the amount of vibration that the machine is producing at any given time. If the machine senses that it is producing too much vibration, it will stop itself and attempt to rebalance its load using a slow speed cycle to redistribute the mass of the load about the basket. These systems work well in most instances, unless the load that is being washed is one that cannot be evenly be distributed (i.e. rugs or an overloaded machine).

Thus, we recommend that the best washing machine to purchase are those with inertial ball balance rings (also ‘balancing rings’), which are available from at least three of the major manufacturers under a variety of trade names and brand names. This design feature, combined with the use of accelerometers, provides, in our opinion, the machine that will give the best vibration reduction performance.

“We are bringing the best and most advanced technology in vibration and shock control to life in products we use every day,” says Fred Miller, President of Seicon Limited.

The ØVIB Washer Stand eliminates vibration in front loaders up to 92%. This is particularly helpful in homes where the laundry room is on the first or second floor. No more scheduling laundry around family and entertainment time. Because the washer stand elevates the machine three inches, a companion dryer stand also is available.

A new website, www.0vib.com, features product information, photos, customer testimonials and a review by Consumer Reports. You can purchase the washer stand and dryer stand online individually or as a combo.

The post Washer Vibration and Noise Problem Solved with ØVIB appeared first on Washing Machine Vibration.

“We are excited to offer a true solution to a difficult problem that many consumers face by developing a platform that incorporates the best vibration-reduction technology available,” said Fred Miller, President and CEO of Seicon Limited. “The ØVIB Washer Stand works with all major brands of front-loading washing machines and can eliminate the need for expensive home renovations in first and second floor laundry rooms.”

Seicon Limited develops and licenses proprietary technology for isolating and controlling vibration and shock. Seicon developed the ØVIB Washer Stand at the request of Neil Drobny, the owner of a front-loading washing machine that vibrated so forcibly during the spin cycle that it rattled dishes in his china cabinet. Seicon then learned that front-loading washing machines often generate vibration problems ranging from keeping babies awake at night to making it impossible to watch television in adjoining rooms.

“Our patented technology virtually eliminates vibration-related problems, and the ØVIB Washer Stand will last at least as long as the washing machine,” said Miller. “In testing, the ØVIB Washer Stand continued to perform perfectly even after 5,000 hours of wash time.”

Drobny says the ØVIB Washer Stand solved his problem. “As a result of Seicon’s innovative platform design, we were able to retain our environmentally friendly front-loading washer, which we otherwise would have had to sell in order to protect our house from the excessive vibration caused by the ultra-high spin cycle,” he said.

Front-loading washing machines clean better, are more energy efficient and use less water than conventional top-loading machines. Because they also spin faster and revolve perpendicular to the floor, many machines create noisy vibrations that can even cause structural damage to a home. In homes with first or second floor laundry rooms, some manufacturers recommend reinforcing laundry-room floors to combat the problem. Some retailers avoid selling these types of machines to customers with laundry facilities on main living floors.

Existing solutions consist primarily of rubber feet or mats that eliminate only a fraction of the vibration and can undergo excessive wear. Washing machines also have been known to fall off rubber feet, causing damage to the washing machine and the floor.

At 2 3/4″ high and 27″ square, the ØVIB Washer Stand is much slimmer than the aesthetic pedestals that manufactures sell to raise washers and dryers off the floor.
