① 阀门电机转矩符合阀门的启闭转矩特性。一般阀门开启和关闭到位短时间内所需的转矩值高, 而在中间
运行状态时所需转矩值仅为开启或关闭最大扭矩值的1/ 3 , 故阀门专用电机的特点是启动力矩高, 过载
能力强。阀门专用电机的最大转矩与额定转矩值之比大于3 倍, 启动力矩与额定力矩值之比也大3 倍。
② 阀门专用电机设计时转子形状细长。因而高速转动的电机在阀门关闭时给阀门密封附加的惯性载荷
小, 既可保证阀门密封面可靠, 又不会使阀门密封面损坏。
③ 由于阀门的操作是断续性的短时工作制, 因而阀门专用电机的工作时间按国家标准规定为 10min , 有的
国外产品时间为15min。
④ 阀门专用电机端面出线, 无接线盒, 无风扇, 自冷却式, 防护性能高。一般制式IP55 , IP65 , 最高级别达
IP68 为潜水型电机。
