网址:www.hzhldj.com 国家二级企业 通过ISO9001:2000质量认证 ZZJ-800系列电动机是一种冶金起重用直流电动机,适用于轧钢机、起重机、升降机和电铲等. 本系列电动机转动惯量低,过载能力大,速度反应快.因而能经受快速而频繁的启动、制动与反转.并具有可靠 性好、调速性能优良、适应可控硅供电下工作等特点. 电机采用圆形整体机座,结构坚固,能承受震动和冲击.全部绕组使用F级绝缘,真空浸渍,与叠片铁心形成整 体,确保绝缘高度稳定和良好散热.此外,电枢绕组与换向器升高片之间用钨极惰性气体保护焊连接,从而增进电 气和机械可靠性. 电动机的基本机构形式为卧式有脚,双轴伸,轴伸端锥度为1:10.出线盒位置从主传动端视之,在电机的右侧. 电动机的定额,性能及外形安装尺寸全部按照国际电工委员会标准IEC34-13《冶金起重用辅机电动机技术规 范》(1980版)和国家标准GB5227《轧机辅传动直流电动机》 电动机的防护和冷却方式有6种: 1. 全封闭、自冷.IP

44、IC410 2. 防滴、强迫通风带骑式鼓风机.IP23S、IC06 3. 防滴、单管道通风.IP23S、IC17 4. 全封闭、双管道通风.IP

44、IC37 5. 防滴、自通风.IP23S、IC01 6. 全封闭、强迫通风带空/水冷却器.IP

44、ICW37A86(仅对ZZJ804-818而言).也可根据用户要求制成 其他形式. 特点和用途 Feature And Uses ZZJ-800 motors are a kind of DC motors used for metallurgy &

hoisting, available for steel rolling machine, crane, elevator and electric excavator etc. The motors have lower moment of inertia(GD),higher overload capacity,and quicker speed response so that it is possible to undergo frequent starting, braking, and repeated change of direction of rotation. Moreover, the motors are reliable, perform well in speed regulating, and can be operated suitably on thyristor continue rolled supplies. The sturdy unitary round frame structure is highly resistant to shock impact.All the windings are vacuum pressure impregnated with class F insulation, to form an integral construction with the laminated cores,ensuring high dielectric stability and excellent heat dissipation.Besides,the connection between armature winding and segment risers is employed by TIG welding (inert gas tungsten are welding), thereby improving the electromechanical reliability. Basic type of construction is horizontal foot-mounted and

2 shaft-end'

s which are 1:10 tapered. Terminal box is located at the right side of motor viewed from motor viewed from the main drive end. Rating,performance and outline mounting dimension all conform to the standard of IEC publication 34-13 (edition 1980) pecification for mill auxiliary motor , and national standard GB5227 Specification for mill auxiliary D.C motor Modes of protection and cooling have

6 kinds: 1.Totally enclosed,self-cooling.IP

44、IC410 2.Drip-proof,force ventilated with built-on blower.IP23S、IC06 3.Drip-proof,single pipe ventilated.IP23S、IC17 4.Totally enclosed,double pipes ventilated.IP
