The top energy efficiency class is available to everyone: what "Sovelmash" offers to the world
Our entire civilization relies on electric motors; they are the main consumers of energy. Humanity is faced with a global challenge: to reduce electricity consumption in order to preserve the planet's ecology. This can be achieved by improving the energy efficiency of motors.
Interest in energy-saving motors escalated in the late 1970s during the oil energy crisis. It turned out that it was much cheaper to save one ton of fuel equivalent than to produce it. Since then, investments in energy-saving technologies around the world have increased manifold.
What are the energy efficiency classes of motors?
The International Electrotechnical Commission (IEC) has developed standards for classifying the energy efficiency of equipment. On these grounds, the European Union has established four energy efficiency classes (IE - International Energy Efficiency). The classification is designed for single-speed three-phase squirrel-cage induction electric motors with a low voltage supply for 50/60 Hz, with a power range from 0.75 kW to 375 kW:
• IE1 — standard class;
• IE2 — high class;
• IE3 — premium class;
• IE4/IE5 — maximum energy efficiency classes today.
The energy efficiency class is determined based on the results of tests, which are conducted in accordance with the international standard, taking into account the power and efficiency performance.
Advantages and drawbacks of energy efficient motors compared to conventional motors
+ Motor efficiency is increased. The higher the efficiency, the less heat loss, which means the motor heats up less and runs longer.
- Higher costs.
- Weight and size are bigger.
- The inrush current is higher.
The world's leading motor and equipment manufacturers are constantly looking for ways to minimize the disadvantages of energy-efficient motors.
Now only "Sovelmash" has the technology that makes it possible to upgrade the energy efficiency class of the motor from IE1 to IE3-IE4 without increasing its weight and dimensions. At the same time, material consumption for the production of motors and inrush currents in their operation are reduced. Such miracle effects are achieved thanks to the "Slavyanka" combined winding technology. You can learn more about the technology by following this link.
The construction of the "Sovelmash" design and engineering technology department, which is to be completed in the 3rd quarter of 2023, will allow the company to develop innovative customized electric motors. The large-scale launch of "Slavyanka" based electric motors on the global market could make the top energy efficiency classes available to the entire world.
