结构特点  Structural characteristics
　　该系列电机采用箱式钢板结构，拆下冷却器或防护罩即可观察和触及电机内部，便于电机的安装维护；转子为绕线式转子，带滑环结构；定子采用F级绝缘真空压力浸渍无溶剂工艺处理(VPI)，使电机具有可靠的绝缘性能和防潮、抗冲击能力；定子和轴承均装有PT100测温元件，电机轴承均有不停机注油和排油装置，提高了电机自身的保护能力和运行效率。当电机功率超过2000kW时，可按用户要求，多配一副出线盒，用于引出三相绕组中的中性点。
This series motors with box type steel structure, can be observed its interior after removing the cooler or protective cover, and esay to be installed and maintained; Wound rotor is installed with slip ring structure; Insulation class F stator made by VPI process, ensure the reliability of insulation, moisture-proof and shock resistance; Temperature senor for stator and bearing, non-stop oil filling and exit pipe, improve the protection ability and operation efficiency of the motors. When the power is more than 2000kW, according to the requirement of customer, another terminal box can be installed to pick up the neutral point of winding.
该系列产品适用于：1、较大的启动转矩；2、输电线路容量不足以启动鼠笼型电动机；3、启动时间长和启动较频繁；4、需要小范围调速。
This series motor can be applied to the requirements as follows: 1. The lager starting torque; 2. Power capacity is not enough to start a squirrel cage motor; 3. Long start time or start more frequently; 4. Adjust speed in a small range.
