Step motor formula relay

The utility model discloses a step motor formula relay, this step motor formula relay include on -off mechanism, control feedback module, step motor and motion actuating mechanism, control feedback module passes through the sampling line and is connected with on -off mechanism, and control feedback module feeds back to step motor through analysis of resistance sampling information and processing, and step motor judges according to received information that the transmission is for motion actuating mechanism again, control feedback module comprise sampling unit, comparing element, analysis and processing unit, pulse output unit, feedback Unit. The technical scheme of the utility model can realize contact resistance automatically regulated, it is reliable and stable, avoided the relay to cause the defect of trouble because of contact resistance is too big, improved the life of relay. 本实用新型公开了种步进电机式继电器，该步进电机式继电器包括开关机构、控制反馈模块、步进电机和运动执行机构；控制反馈模块通过采样线与开关机构连接，控制反馈模块通过电阻采样信息分析和处理反馈给步进电机，步进电机根据接收到的信息判断，再传递给运动执行机构；控制反馈模
