Industrial consumption accounts for a significant portion of China's total electricity consumption, and motors occupy a major position in industrial electricity consumption.
Therefore, the potential for engine energy saving is great, and highly efficient technologies and equipment will play an important role. The prospects for high-efficiency engines are also positive in the repair industry.
According to the document on the minimum permissible values and energy saving assessment of small and medium-sized three-phase asynchronous motors, China has three classes: the first is ultra-efficient motors, the second is high-efficiency motors, and the third is conventional motors. A research report on the industrialization of speed control notes that motors consume 66% of China's total electricity generation, and their operating efficiency is 10 to 20 percentage points below foreign best practices.
The frequency converter adjusts the speed according to actual demand and allows you to operate in the most economical mode, significantly reducing light load consumption and overall energy consumption. Typically, savings are 20–30%, in some cases they exceed 50%, and the payback period is about 2 years.
Compared to conventional motors, the use of quality materials and optimized design reduces the energy consumption of high-efficiency motors by approximately 20% on average; Ultra-efficient motors reduce energy losses by more than 30%. The price of a high-efficiency motor is approximately 15-30% higher than a conventional Y-series motor, but the additional investment typically pays for itself within 2 years and provides life-cycle savings.
There are two main ways to improve efficiency: adjusting the speed with a frequency converter or using highly efficient motors. Therefore, the markets for high-voltage converters and high-efficiency motors are of significant size.
