  • Relationship between Motor Torque and Motor Volume

    It can be stated boldly – and accurately – that the overall volume of a motor is determined by the torque it must produce: the larger the volume, the greater the torque. Of course, there may be exceptions to this rule, but as a general guideline for motor selection, it is very useful.

  • What conditions need to be met for exporting motors to Taiwan?

    Low-voltage motors are subject to mandatory BSMI inspection and control, while high-voltage motors are not subject to this restriction. Currently, high-voltage motors have no mandatory energy efficiency regulations and do not require registration in any official system; they only need to comply with relevant specifications for high-voltage electrical equipment.

  • Overview of Mexico's NOM and FIDE Certifications

    For Chinese companies planning to export products to Mexico, understanding the local compliance certification system is the first critical step to successfully entering the market. Among the various certifications in Mexico, NOM and FIDE are the two most relevant for electronic and electrical products. The former is a mandatory market access standard, while the latter is a voluntary energy efficiency label. This article provides a systematic overview of the key aspects of both certifications, offering practical compliance guidance for exporters.

  • What is the difference between the routine test and the type test for high-voltage three-phase asynchronous motors?

    The core difference between the routine test (factory test) and the type test for high-voltage three-phase asynchronous motors is:
    The routine test is a "factory pass certificate" performed on every motor to verify the manufacturing quality of each unit. The type test is a "design validation report" performed on a sample from the same specification to verify the design and performance compliance of the entire series.

  • Three Types of Energy Efficiency Labeling for Imported Electric Motors in China

    The current mandatory Energy Efficiency Label catalog in China covers 38 product categories. Key motor-related products included are:
    • Permanent Magnet Synchronous Motors
    • High-Voltage Three-Phase Squirrel-Cage Induction Motors
    The implementation rules for these products are specified in the 2025 catalog. For Permanent Magnet Synchronous Motors, the new rules took effect on January 1, 2026. For High-Voltage Three-Phase Induction Motors, the rules will take effect on April 1, 2026.
