產(chǎn)品簡(jiǎn)介(General introductions)

    YBBP系列隔爆型變頻調(diào)速三相異步電動(dòng)機(jī)(以下簡(jiǎn)稱為:電動(dòng)機(jī))，是我公司根據(jù)市場(chǎng)需求而開發(fā)的新產(chǎn)品，與變頻器配合使用，可以實(shí)現(xiàn)較寬范圍內(nèi)平滑無級(jí)調(diào)速，調(diào)速范圍、動(dòng)態(tài)響應(yīng)、調(diào)速精度、低頻轉(zhuǎn)矩、轉(zhuǎn)差補(bǔ)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(chǎng)所需要調(diào)速及其節(jié)能需要的理想驅(qū)動(dòng)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 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.

電動(dòng)機(jī)按GB 3836.2和MT 451（僅對(duì)ExdI）的規(guī)定制成隔爆型，其防爆標(biāo)志為ExdI、ExdIIBT4、ExdIICT4。ExdI、ExdIIBT4產(chǎn)品范圍機(jī)座號(hào)H80～500，ExdIICT4產(chǎn)品范圍機(jī)座號(hào)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.

電動(dòng)機(jī)的冷卻方式為IC411自扇冷系列，IC416強(qiáng)迫通風(fēng)系列

IC411自扇冷系列機(jī)座號(hào)范圍為H280及以下電動(dòng)機(jī)。

IC416強(qiáng)迫通風(fēng)系列機(jī)座號(hào)范圍為H160及以上電動(dòng)機(jī)。

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.

主體外殼防護(hù)等級(jí)為IP55。

The protection class of the enclosure is IP55.

電動(dòng)機(jī)絕緣等級(jí):機(jī)座號(hào)H355及以下為F級(jí)，機(jī)座號(hào)H400及以上為H級(jí)。電磁線采用變頻專用電磁線，絕緣體系進(jìn)行特殊工藝處理，具有良好的電氣、機(jī)械、防潮及熱穩(wěn)定性，以適應(yīng)變頻電源的要求。

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.

電動(dòng)機(jī)轉(zhuǎn)子采用鑄鋁結(jié)構(gòu)，采用高精度的動(dòng)平衡設(shè)備，低不平衡質(zhì)量確保電動(dòng)機(jī)運(yùn)轉(zhuǎn)平穩(wěn)、振動(dòng)小、噪聲低。

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.
