YBBP系列隔爆型變頻調速三相異步電動機(以下簡稱為:電動機)，是我公司根據(jù)市場需求而開發(fā)的新產(chǎn)品，與變頻器配合使用，可以實現(xiàn)較寬范圍內平滑無級調速，調速范圍、動態(tài)響應、調速精度、低頻轉矩、轉差補償、功率因數(shù)、效率等方面均有很大的優(yōu)越性，是滿足煤炭石油化工等存在性氣體環(huán)境的場所需要調速及其節(jié)能需要的理想驅動產(chǎn)品。

YBBP series flame-proof frequency-control three-phase asynchronous motors (hereinafter referred to as “the motors”) are a series of new products developed by our company to meet the market demand. In conjunction with a frequency inverter, the motor can realize smooth step less speed variation over a wide range. This series has great advantages in speed regulation range, dynamic response perbance, speed regulating precision, low-frequency torque, slip compensation, power factor, efficiency, etc., and serves as the ideal driving equipment to meet the requirements of speed regulation and energy saving for devices used in coal mines, petrochemical industry and other environments with explosive gases.
