YBBP Series Flameproof Variable-Frequency Speed-Regulating Three-Phase Asynchronous Motor

1. Product Overview:

The YBBP series flameproof variable-frequency speed-regulating three-phase asynchronous motor is a new product developed by our company in response to market demands. When used in conjunction with a frequency converter, it can achieve stepless speed regulation within a wide frequency range, featuring a wide speed regulation range, fast dynamic response, and high speed regulation accuracy. The power grades and installation dimensions of this series of motors comply with the International Electrotechnical Commission standards (IECC standards, whose corresponding relationship is the same as the German DIN42673 standard), which is conducive to the matching of export equipment and the spare parts of imported equipment.

Applications: It is suitable for places with explosive gas mixtures in industries such as petroleum, chemical industry, mining, metallurgy, and electric power. Its flameproof grades are DI, DIBT4, and DIICT4, which can meet the requirements of variable-frequency speed regulation with frequencies of 3-50-100Hz, making it an ideal power equipment.
