YBBP series flameproof variable frequency speed regulating three-phase asynchronous motor is a new product jointly developed by the German technical team and the Chinese technical team. It fully absorbs the excellent genes of European explosion-proof motor design, and has a brand-new appearance design to improve the safety performance of the motor. When used with a frequency converter, it can achieve stepless speed regulation in a wide frequency range. It has the characteristics of wide speed regulation range, fast dynamic response, and high speed regulation accuracy. The power level and installation dimensions of this series of motors comply with the standards of the National Electrical Engineering Commission (IEC), and their corresponding relationship is the same as the German DIN42673 standard, which is conducive to the matching of export equipment and spare parts of imported equipment. This product is a brand-new upgraded product launched for the world.
