产品简介(General introductions)

    YBBP系列隔爆型变频调速三相异步电动机(以下简称为:电动机)，是我公司根据市场需求而开发的新产品，与变频器配合使用，可以实现较宽范围内平滑无级调速，调速范围、动态响应、调速精度、低频转矩、转差补偿、功率因数、效率等方面均有很大的优越性，是满足煤炭石油化工等存在性气体环境的场所需要调速及其节能需要的理想驱动产品。

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 performance, 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.

电动机按GB 3836.2和MT 451（仅对ExdI）的规定制成隔爆型，其防爆标志为ExdI、ExdIIBT4、ExdIICT4。ExdI、ExdIIBT4产品范围机座号H80～500，ExdIICT4产品范围机座号H80～450。

The motors are manufactured into flameproof type and the flameproof property conforms to GB 3836.2 and MT451 (only for ExdI), and their flameproof marks include ExdI, ExdIIBT4, and ExdIICT4. The frame size range of products with ExdI and ExdIIBT4 is H80-500, and the range of the products with ExdIICT4 is H80-450.

IC411自扇冷系列机座号范围为H280及以下电动机。

IC416强迫通风系列机座号范围为H160及以上电动机。

The motors have two cooling methods: IC411 (fan-ventilated series) and IC416 (forced ventilation series)

The frame size range of the fan-ventilated series (IC411) is H280 and below.

The frame size range of the forced ventilation series (IC416) is H160 and above.

主体外壳防护等级为IP55。

The protection class of the enclosure is IP55.

电动机绝缘等级:机座号H355及以下为F级，机座号H400及以上为H级。电磁线采用变频专用电磁线，绝缘体系进行特殊工艺处理，具有良好的电气、机械、防潮及热稳定性，以适应变频电源的要求。

The motors’ insulation grade: grade-F for H355 and below, grade-H for H400 and above. Special electromagnetic wire for frequency conversion is used. The insulation system, which is treated by special process, has good electrical and mechanical properties, moisture resistance, and heat stability, and meets the requirements of variable-frequency power sources.

电动机转子采用铸铝结构，采用高精度的动平衡设备，低不平衡质量确保电动机运转平稳、振动小、噪声低。

Cast-aluminum rotors are used in the motors. High-precision dynamic balance equipment and low unbalance mass guarantee the rotor’s smooth running and low vibration and noise.
