制動三相異步電動機
制動三相異步電動機系列電動機是Y系列三相異步電動機的派生產(chǎn)品,具有結(jié)構(gòu)緊湊、制動可靠、定位準確、制動力矩調(diào)節(jié)范圍大等優(yōu)點,適用于各種升降機械,傳送機械,冶金化工設備及輕、重工業(yè)系統(tǒng)中要求快速停車,準確定位場所。
YEJ系列電機由Y系列異步電動機附加交流制動器組合而成,其安裝尺寸與Y系列三相異步電動機相同,功率等級和轉(zhuǎn)速的對應關(guān)系與Y系列電機相同,符合IEC標準,與國外同類產(chǎn)品間有良好的互換性。
YDEJ系列電機由YD系列變極三相異步電動機附加交流制動器組合而成,其安裝尺寸與Y系列三相異步電動機相同,功率等級和轉(zhuǎn)速的對應關(guān)系與YD系列電機相同,符合IEC標準,與國外同類產(chǎn)品間有良好的互換性。
YEJ系列和YDEJ系列電動機的交流制動器由三相380V電源直接供電。交流制動器不僅制動速度快(比直流平面制動器快100倍),而且由于無二極管整流,因此大幅度提高電機可靠性和使用壽命。
本系列變頻電機可制成直聯(lián)式結(jié)構(gòu),安裝型式和尺寸參見直聯(lián)式安裝表。
本系列變頻電機可以按用戶提供的圖紙設計并制造。
YEJ Series 3-Phase Frequency Conversion and Variable Speed Asynchronous Motor with Brake, and YDEJ Series 3-Phase Frequency Conversion and Variable Speed Asynchronous Motor with Brake are the variation products of the Y series 3-phase asynchronous motor with the advantages of compact in size, reliable AC brake, accurate position and wide range of adjustable braking torque. It is suitable for rapidly stopping applications used in the various purposes, such as hoisting machines, conveying machines, metallurgical equipments, and chemical industrial equipments.
The YEJ series and YDEJ series motors are respectively composed of Y series and YD series motors combined with AC brakes. The mounting dimension, power rating and rotating speed of them are as same as those of corresponding Y series and YD series motors. They meet IEC standard and have the remarkable crossing-over and uniform features with same kind of products manufactured both in China as well as from overseas.
The AC brake is powered directly from a three phase power supply without rectified diodes. The AC brakes are not only quick response braking (100 times quicker than a DC single phase brake) but also have improved reliability and long service life. The advantages of AC brakes also include precise positioning, such as no axial movements, and the capability of a wide adjustable range of braking torque, such as from zero (0) to any desired values. The AC brake is an approved patent from the National Patent Bureau. The approval patent number is: 97206492.3
The motor has been awarded an approved patent from the National Patent Bureau with number of ZL 200820057339.5.
Above series motors are available for used in the direct connection between the motor and the gearbox. Please refer to tables below for details.
These series motors can be customized designed and produced to meet your request.
