Market Size of High-Efficiency Three-Phase Induction Motors
High-efficiency three-phase induction motors are core equipment for industrial energy conservation. China is the world’s largest producer and consumer, and its market continues to expand driven by policy support, energy-efficiency upgrades, and industrial transformation. IE4 and IE5 ratings have become mainstream, with intelligentization and integration emerging as the key trends.

Core driving factors
Policy Mandatory Upgrade
GB 18613-2020: Effective 2021, IE3 is the minimum efficiency level for new installations, with IE4+ given priority for new projects.
Motor Energy Efficiency Improvement Plan: By 2025, the share of newly installed high-efficiency motors shall be no less than 70%, and low-efficiency motors shall be phased out.
Dual Carbon Goals + Industrial Carbon Peak: Motor systems account for over 65% of industrial electricity consumption, creating a strong and rigid demand for energy-saving upgrades.
Local subsidies: For example, Jiangsu provides a subsidy of RMB 30 per kilowatt for IE4+ motors, thereby boosting procurement growth.
Economic-driven
High-efficiency motors consume 5%–20% less electricity than standard motors, with the additional cost recouped in 1–2 years.
With rising electricity prices and long-duration operation (over 3,000 hours per year), the cost-effectiveness of IE4/IE5 motors becomes increasingly prominent.
Mature technology and supply chain
The YE3/YE4/YE5 series is standardized and compatible with the mounting dimensions of the Y series, enabling low-cost direct replacement.
The widespread adoption of high-grade silicon steel, cast-copper rotors, low-resistance fans, and other technologies has led to improved efficiency and reduced costs.
Industrial Automation and Digital Transformation
Smart factories, variable-frequency drives, and IoT-based monitoring are driving the demand for efficient, intelligent integration.
