Transforming industrial growth through energy efficient technologies and motor independence

Sustainability at the forefront of innovation

In the current era of technological progress, sustainability has emerged as an important component in order to reduce the monetary and environmental costs that individuals and industries are incurring across industries which has pressed organisations to re-think their levels of energy efficiency.

Across industries, the energy-efficiency discussion has forced the development of new motor technologies and the reinvention of existing, older technologies – with a section that is genuinely interested in having a positive effect on the environment, or others who are simply following the ever-intensifying standards and regulations.

In the past, the induction motor (IM) was the only type of electrical motor used in industrial applications. It is still today one of the most commonly used motors in most applications.Thanks to the advent of AC drives, the high-efficiency synchronous reluctance motor (SynRM) can now be optimized for energy efficiency. There are also internal and surface-mounted permanent magnet motors.

However, each motor type has its advantages and drawbacks; and the key is finding the one that best fits your application.

For optimal energy efficiency, it is important to focus on the motor controller – the AC drive. While it is known that AC drives reduce the electricity consumption of motors under variable torque loading (Example: fans and pumps), they can also be configured to run in regenerative mode where braking energy is fed back into the power supply instead of being lost as heat.

However, the big question that remains across sectors is – Are there any constraints on what AC drives we can use with what motors?

Four reasons why motor independence matters:

  • Flexibility: In this sense, flexibility means the ability to accommodate changing customer specifications and new technological trends over the entire lifetime of an application. If the drive is compatible with all state-of-the-art motor technologies, it’s just a case of including new motor algorithms into software updates of the drive when needed.
  • Fast replacement/retrofitting: There may be occasions when there are bottlenecks in delivery by a particular motor supplier. Similarly, it may be difficult to find an identical replacement motor in a remote site or location. In these instances, your only option might be to choose a different motor technology. Having a drive that’s compatible with all motor technologies gives you the freedom to choose another, more available, motor technology to avoid costly downtime.
  • One drive fits all: In the case of multiple installations like in large plants, having the same motor-independent drives installed throughout the entire plant mean there’s a lower spare parts stock inventory, simplified staff training and more straightforward maintenance.
  • A future-proof solution: Using automatic motor adaptation, motor-independent drives can deliver optimal performance of any motor both now and throughout the lifetime of the application. Motor-independent drive suppliers continually test new motor technologies in order to develop new algorithms for compatibility. Independently optimized components adapt completely to a variety of applications. For example: OEMscan therefore design the highest-performance drive/motor system for a specific niche application.


Product efficiency at its best: Danfoss EC+ solutions

The launch of the Danfoss EC+ solutions is set to create a new benchmark in the Motor Independence Technology with the promise of Highest Fan Efficiency (Fan + Motor + Variable Frequency Drive) of up to 85 percent.

In comparison to the traditional EC fans that are available in the market, the new solution is upto 25 percent more efficient.

It can be used to efficiently control Induction Motors (IM), Permanent Magnet Motors (PM) and Multiple PM/IM Motors and is the host of HVAC intelligence that includes Fire Mode, Filter Monitoring, Temperature Optimizer and Seamless BMS integration with no requirement of special gateways or external controllers.

The in-built fan has an air flow of up to 400,000 CMH and can withstand pressure of upto 3000 Pascal with lower noise levels. They can be easily retrofit owing to their compact size and helps in significantly reducing the size of the AHU.

Energy Savings at its core: Next Gen High Power Automation Drive with size E            

The newly launched Danfoss VLT drive has been reduced in size by 73%, which in turn reduces space constraints in the cabinet or control room which reduces capex on floor space and air-conditioning cost. The high-power density of the product is achieved by the maximum use of silicon capacity, using cutting edge technology in thermal management. Its efficient designing allows for greater power sizes to be integrated in a single drive. With its built-in options such as fuses, mains shield, brake chopper, RFI Filter, USB through door and heat sink access panel, the drive eliminates the need for an external cabinet when only the basic options are needed, thereby saving space and equipment cost.

The back-channel cooling facility and the overall reduced size of the new VLT Drive helps in reducing the scale of air-conditioning that is required for the room, leading to major savings in the up-front cost as well as operational expenses. 90% of the heat losses are exhausted directly outside the enclosure which dramatically reduces the temperature rise and reduces the contamination of the electronic components.

“In the current scenario where India is facing acute shortage of energy, Danfoss’ next-generation variable frequency drive can easily save between 18-20% of the energy input. This can help in reducing the carbon footprint of the industries which proves to be beneficial to both the customer as well as the planet”, said Mr.Palaniswamy PL, Director, Sales, Marketing & Services, Danfoss Drives.

The drives can be utilized across industries such as Cement, Mining and minerals industry, Cranes & Hoists, Sugar, Paper, Chemical, Waste and wastewater management, HVAC (Heating, Ventilation and Air Conditioning), Marine and offshore, refrigeration, food and beverages industry, lifts and escalators management, etc. which highlights the versatility of the product.
