Docking of United States NEMA standards and Chinese motor standards

Background

In the global motor industry, the United States National Electrical Manufacturers Association (NEMA) standard and the Chinese motor standard play an important role in their respective markets. With the acceleration of globalization and the continuous integration of international markets, it is particularly important for motor manufacturers to understand and align with these standards.

As a leading motor manufacturing company, BG Motor is committed to promoting the alignment and internationalization of industry standards, and the following is our latest news on the alignment of NEMA standards with Chinese motor standards.

Introduction to NEMA standards

United States NEMA standards are a series of technical standards for electrical and electrical equipment developed by the National Electrical Manufacturers Association of United States. NEMA standards cover aspects such as motor performance, design, testing, and safety, and are designed to ensure high performance and reliability in a variety of applications. NEMA standards have clear regulations on the size, power, efficiency, noise and protection level of motors, and are an important reference for motor products in the United States market.

China's motor standards are formulated by the Standardization Administration of China (SAC) and related industry associations, mainly including GB (National Standard) and JB (Machinery Industry Standard) series. These standards cover aspects such as technical requirements, test methods, safety specifications, etc. for electric motors.

China's motor standards aim to ensure the quality, safety and environmental adaptability of motors, while promoting technological innovation and industrial upgrading.

The necessity of standard docking

BG Motor actively responds to the international market demand and is committed to promoting the docking of NEMA standards with Chinese motor standards. We achieve effective alignment of standards through the following measures:

1. Technical docking: In the process of product design and manufacturing, we fully consider and integrate the technical requirements of NEMA standards and Chinese motor standards to ensure that products can meet the requirements of different standards in the global market.

2. Certification & Testing: We conduct standardized testing to ensure compliance and high performance of our products in different markets by obtaining relevant international certifications.

3. Market research and adjustment: We pay close attention to the standard changes and technical trends in the international market, adjust product specifications and standards in a timely manner, and keep pace with the global market demand.

4. Cooperation and exchange: We maintain close contact with the International 

Organization for Standardization and industry associations, participate in the standard formulation and revision process, and promote the standardization process of the industry.

Standard docking details

Range of standard mounting sizes for NEMA motors: The standard mounting sizes for NEMA motors range from 15mm ×15mm for NEMA6 to 106mm ×106mm for NEMA42.

12 different types of NEMA motor standard and Chinese standard installation size:

NEMA6：15mm×15mm

NEMA8：20mm×20mm

NEMA10：25mm×25mm

NEMA11：28mm×28mm

NEMA14：35mm×35mm

NEMA16：39mm×39mm

NEMA17：42mm×42mm（Also known as NEMA 17 stepper motors）

NEMA23：57mm×57mm（Also known as NEMA 57 stepper motor）

NEMA24：60mm×60mm

NEMA34：86mm×86mm

NEMA42：106mm×106mm

Application areas of NEMA motor standards:

NEMA motor standards are widely used in a variety of equipment and systems, including but not limited to 3D printers, medical devices, semiconductor processing equipment, valve control, X-Y benches, etc. These motors provide precise control and reliable performance to meet the needs of a wide range of applications.

In summary, BG Motor will continue to be committed to promoting the docking of NEMA standards with Chinese motor standards and promoting the international development of the motor industry. By strictly following international standards and continuous innovation, we strive to provide high-quality motor products to customers around the world and improve the overall level of the industry. We believe that the alignment of international standards will contribute to the development of the industry and the prosperity of the global market.
