How Intelligent Motion Controls Use Automated Processes to Make HVAC Processes Greener and More Efficient

Posted by Sam Pelonis | May 10, 2019 2:13:52 PM | 0 Comments

Brushless DC fans and blowers need optimal motion control. When complex or demanding applications need precise levels of output, intelligent motion control systems can keep parts safe while still ensuring high-quality production cycles. These intelligent motion controls (IMCs) have in-board circuits that use programmable, information-gathering features to develop air movement “intelligence” and learn how the parts need to operate in different environments.

IMCs are ideal for:

  • Green applications in which facility managers want to improve reliability, the equipment’s life expectancy, and energy efficiency.
  • Systems that need consistent monitoring and cooling—IMCs have multi-alarm connections to prevent complete system failures, reduce voltage fluctuations, and have more reliable control.

When businesses install IMCs, they will make their facilities greener and more efficient. Read on to learn about all the different benefits IMCs can bring.

Top Solutions

There are several different types of IMCs that can add control to the operation and maintenance of brushless DC fans and blowers. The top four IMC solutions are:

Rotation Detectors

A smart rotation detector can monitor fan operations in parallel circuits to detect ongoing circulation as well as potential failures or stopped fans. These systems give a “high” output signal to the monitoring interface while the fan rotates. That same signal turns to “low” or “off” based on the fan’s status. This allows operators and maintenance teams to investigate potential problem areas more quickly because the system automatically notifies them when a fan stops working rather than requiring them to monitor changes in temperature.

Rotation detectors use the same hardware as the frequency generator (tachometer), which we also describe below. Once the detector is added to an array of fans, it operates as part of the facility’s multi-alarm connection.

Rotation Detectors

Inrush Current Protection

When motors, heating elements, transformers, and power supplies turn on, the current surges. This short-lived inrush current can damage electronic parts if it isn’t properly controlled.

Facility managers use inrush current protection to slow the flood of current to the equipment. This technology allows fan blades to speed up at a more gradual rate through incremental increases of current. The process takes approximately ten seconds during startup, and it protects both the circuits and the moving parts from damage.

Inrush Current Protection

Auto Start

Sometimes, fan blades get blocked by temporary obstructions. Auto starts control the current output in these circumstances. First, the current can be reduced to zero when an obstruction is detected so the fan blades don’t damage themselves. This feature is called locked rotor protection. Then, the auto-start control uses a second feature, restart with current limit, to guarantee the restart of the rotor once it is released.

Auto Start

Frequency Generator (Tachometer)

This IMC solution is an open collective output type that produces an analog voltage based on the fan’s motor speed. These parts provide feedback and can be used to measure the speed of motors, rotors, and engines.

Frequency generators use the same hardware as rotation detectors, and they’re powered by the power supply voltage. A tachometer will send a square wave signal to the reading device if the collector connects with a pullup resistor. This part can handle a maximum collector voltage of 72 V DC and current of 10 mA.

The Top Six Benefits of Working With High-Performance Blowers

Posted by Sam Pelonis | Feb 25, 2019 10:10:46 AM | 0 Comments

High-performance blowers are a critical aspect of keeping a plant or factory running; smaller and more compact options are also useful in the average family home. These types of blowers ensure that air can move continuously while maintaining an energy-efficient level of operation.

High-performance blowers provide increased airflow, which reduces the amount of cold spots in the home and improves the performance of humidifiers and air purifiers. They also feature nearly silent motors, so you may not even hear the system running.

Applications and Uses of High-Performance Blowers

Blowers are common in plants and factories because they help combat pressure rising in pipes that feature components such as filters, grates, valves, heaters, and condensers. They are often deployed with fairly narrow pipes to promote a higher and stronger flow; this can be especially beneficial in scenarios where fumes need to be removed from an area.

Air velocity is also an asset in:R1232-28_Titan_Series_DC_Blower.jpg

Water Resistant DC Fans for Harsh Environments

Posted by Sam Pelonis | May 19, 2017 4:05:13 PM | 0 Comments

Operating in harsh conditions can present serious challenges for companies across various industries, but deadlines must be met no matter how extreme the environment. Severe weather, in particular, can affect all types of industrial processes and equipment.

Severe Environments Cover.jpg

Power supply equipment, for instance, is especially susceptible to extreme weather conditions, as is heating, ventilation, and air conditioning (HVAC) equipment. Without the proper equipment and guidelines in place, industrial facilities run the risk of increased downtime, added costs, and worker injuries. To ensure efficiency and minimize downtime and unnecessary expenditures, precautions must be taken to protect equipment and keep workers safe in hazardous areas.

Hazardous-Area Classification

The National Electrical Manufacturers Association (NEMA), Underwriters Laboratories(UL), the National Fire Protection Association (NFPA), and a number of other industry organizations publish standards classifying areas that are considered hazardous.

A “hazardous area” refers to any area, indoors or outdoors, with — or with the potential for — harsh conditions, such as gases in chemical and petrochemical plants, dangerous fumes in food processing facilities, or the intermingling of fluids with electrical components.

How Pelonis Helps Ensure Mobile Satellite Communications

Posted by Sam Pelonis | Nov 11, 2015 11:00:00 AM | 0 Comments

While most of us understand the basics of satellite communications such as a TV signal sent from space, it can be hard to envision the satellite itself as a piece of working machinery. For one, most of the general public has never actually seen a large mobile satellite hub. Second, space can be a difficult working area to comprehend.

How Pelonis Helps Ensure Mobile Satellite CommunicationsSatellite equipment features an intricate layout of electrical components that function just as they would in a manufacturing environment, computer server room, or similar set up. This means that satellite technologies heat up just like other equipment, and so the need for cooling measures is critical for a few reasons:

• Satellites that malfunction or shut down could cripple networks that are essential for communication and safety.
• There is little to no capabilities to send support technicians to work on inoperable satellites.
• The environment that mobile satellite communications operate in is rugged and unpredictable.

Since the reliability of these mobile satellite communications is so essential, companies that operate in this industry must use innovative and dependable ways to keep their equipment functional. Pelonis was recently faced with this issue when a customer needed a blower that could cool a number of on-board system components.

This was no “stock” product, however, as the blower was to be featured on a mobile satellite vehicle and needed to be absolutely resistant to moisture and dust. In addition, the blower needed to protect the system's circuit board, cable connectors, and inlets.

Pelonis was able to find the solution with a high speed 24 volt DC blower that fit within an aluminum closure and was finished with a moisture and dust resistant coating. We also added a protective, customized inlet guard where needed and did so with an optimum turnaround time. The design was tested and approved and now operates to keep mobile satellite equipment cool and running efficiently, so that communication like calls, texts, and social media posts during a favorite TV show are delivered uninterrupted.

Fans & Blowers Experience Industrial Market Growth

Posted by Sam Pelonis | Jan 21, 2014 9:00:00 AM | 1 Comment

As in the U.S., the European manufacturing industry suffered deep consequences as a result of the recession of 2008.

Construction projects slowed or came to a complete halt, which hurt all sectors of the industry, including the market for fans, blowers, and heating elements.

According to some reports, however, the fan and blower industry seems poised for a comeback, which is welcome news for workers, manufacturers and customers in Europe and beyond.

Projected European Market Growth

Fotosearch_k15003822In 2011, Companies and Markets, a leading global aggregator of business information, released a report that analyzed 27 European Union countries to determine the health of the European market for ventilation equipment. They examined shipments of equipment such as axial fans, centrifugal fans, and cross flow fans, among others.

As a result of their research, Companies and Markets predicted that the European market would reach a value of about $6.75 billion by 2015. In other words, they expect that the market will grow by at least 8% more per year than in 2006, before the recession hit. In 2006, the European industry for fans was valued at $3.37 billion.

According to another report from Research and Markets on the UK market in particular, the ventilation industry—which includes both domestic and non-domestic ventilation products—has, in recent years, been revived “by positive levels of exports and after-market sales.”

The report attributes better sales to the government’s renewed focus on health, safety and energy efficiency. The data suggests that new building and environmental legislation set by the government has “stimulated product innovation and development.”

A Bright Future for the European Market

Hopeful forecasts from leading market researchers suggest that the European market for fans and blowers is likely to continue improving in the near future. As the world slowly recovers from the global financial crisis of 2007 and 2008, members of the industry can look forward to a reprieve from what was once a stagnant market.

Automation & Smart Technology for DC Brushless Fans & Blowers

Posted by Sam Pelonis | Jan 6, 2014 9:00:00 AM | 0 Comments

Automation is now a buzz word and hot technology trend in both the consumer and manufacturing worlds, so it is interesting to consider how various motion controls would work in a fully integrated and automated society. 

To what degree could every aspect of a home’s HVAC and appliances be operated via intelligent controls, and to what extent could a manufacturing environment be controlled by smart automation?

blogThe use of Intelligent Motion Controls in DC brushless fans and blowers has already arrived.  With Intelligent Motion Controls, the movement of air is now smarter. 

The inclusion of full-wave-in-board circuit design and multiple features leaves no doubt that intelligence has enhanced air movement.

A few Intelligent Motion Control features for DC brushless fans and blowers include:

  • Inrush Current Protection – Allows the power to be turned on to supply current to the fan.  The current begins at zero and gradually increases until the fan reaches its maximum speed and rated current.
  • Auto Start – An intelligent motion control ensures that if a fan’s blade is blocked and released, the fan will automatically restart.
  • DC Voltage Signal Control – The DC Voltage Signal Control (VPWM) controls the speed by applying an external DC voltage signal.
  • Automatic Temperature Control – When the Automatic Temperature Control is applied, the upper and lower temperatures may be selected, as well as the choice of maintaining a minimum RPM below the minimum temperature chosen.

These are only a small sampling of the features that Intelligent Motion Controls provide to fans and blowers.  You can learn more about Intelligent Motion Controls in DC brushless fans and blowers by downloading our free eBook.
