Driving motors with frequency converters has become an irreversible trend. In practice, however, improper matching between the converter and the motor often leads to various issues.

A frequency converter (also called a variable frequency drive, VFD) is a power control device that converts a fixed‑frequency AC supply into an AC output with adjustable frequency and voltage. Most converters in use today adopt the AC‑DC‑AC conversion method (VVVF or vector control).

In industrial power distribution and equipment selection, calculating the rated current of a high‑voltage motor is a fundamental yet crucial task. Many engineers new to high‑voltage systems may think it is complicated, but in fact its core principle is the same as that for low‑voltage motors – it all comes down to power, voltage, and power factor.

In short, CE marking is the “passport” for products to enter the EU market; ATEX is one of the specific regulations that explosive‑atmosphere equipment must satisfy to obtain that CE marking; and IECEx is an “international passport” designed for global mutual recognition.

Since a reducer is a transmission device, many faults often occur during its operation due to external working conditions (e.g., bearing heavy loads) and internal factors.

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.

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.

KC Certification (Korea Certification) is a mandatory certification implemented by the Korean government to ensure the safety of electronic products and consumer goods. The Korean market has strict requirements for product safety and quality, and obtaining KC Certification is crucial for products to enter the Korean market.
