[Reprinted] Application of High-Efficiency Water-Cooled Permanent Magnet Synchronous Motors in the Modified Plastics Compounding Industry

2025-08-06 15:31

With the gradual implementation of China's "dual carbon" policy, manufacturers in the modified plastics industry are facing dual pressures: on one hand, they need to reduce energy consumption to control costs; on the other hand, they must cut carbon emissions to meet environmental requirements. Simultaneously, customer demands for green product certifications are also continuously rising.


Suzhou LEOG Motors Technology Co., Ltd. (hereinafter referred to as "LEOG Motors") has innovatively leveraged its advanced technological expertise accumulated in the new energy vehicle motor sector to develop a low-voltage, high-power, high-efficiency water-cooled permanent magnet motor solution specifically designed for the extruder industry. This technological breakthrough has brought revolutionary changes to the modified plastics compounding sector. 


LEOG Motors employs a uniquely designed integrated die-cast water-cooled frame, incorporating internal cooling channels within the wall of the frame. This innovation fundamentally resolves the "thermal island" issue inside the motor. The advanced cooling mechanism ensures stable operation even in the harsh, dusty environments typical of extruders, effectively addressing the problem of motor overheating-induced downtime. As a result, it extends equipment lifespan and reduces production costs. 


In traditional production lines, asynchronous motors drive the operation of twin-screw extruders. These "electricity-guzzling beasts" are not only bulky and occupy valuable factory space but also consume substantial amounts of electricity during continuous operation. Industry data shows that motor energy consumption accounts for over 60% of the total energy consumption in the entire extrusion production process.


Facing industry "pain points," LEOG Motors' water-cooled permanent magnet motors offer significant application advantages, effortlessly addressing traditional energy consumption challenges and better achieving cost reduction and efficiency improvement.


1.50% reduction in size and approximately 65% reduction in weight: Significantly saves equipment installation space and lowers overall procurement costs.


2.Energy efficiency ≥ IE5, aligning with internationally leading standards.


3.A wide high-efficiency range enables optimal performance under varying load conditions.


4.Average noise level below 75 dB: Notably improves the working environment in the workshop. 


At the same time, LEOG Motors has developed a comprehensive intelligent energy-saving solution based on its motors and drives. This solution, integrated with its self-developed intelligent gateways and smart energy management platform, offers clients a complete suite of strategies for energy conservation and cost reduction.


Advantages of LEOG Motors' Integrated Intelligent Control and Energy-Saving Solution:


1.Independently developed inverter;


2.The inverter features an integrated high-speed real-time network Profinet protocol stack and algorithm;


3.AI-powered energy management platform with adaptive energy-saving modes and system optimization algorithms.


The application value of water-cooled permanent magnet motors has surpassed the scope of single-unit energy savings, aiming to become a key driver in promoting the green transformation of the entire modified plastic blending industry. Currently, while launching standardized series platforms, LEOG Motors also offers customized motor services tailored to industry-specific power matching needs. The company has developed numerous customized products for applications such as screw extruders, plastic machinery, and granulators, effectively enhancing equipment power matching capabilities and advancing the industry's development.


As environmental regulations tighten worldwide and the concept of sustainable development takes root, technological innovation is becoming the core driver of industrial transformation. LEOG Motors will continue to expand its investment in research and development, continuously enhancing the technological advantages of its high-efficiency water-cooled permanent magnet synchronous motors. By enabling more enterprises to upgrade and retrofit their systems, LEOG Motors aims to genuinely achieve cost reduction, efficiency improvement, and green transformation, while providing high-efficiency power solutions for a broader range of industries.
