摘要
本文介绍的多功能手电钻控制器,采用电压负反馈、电流正反馈,并有电流截止负反馈的保护装置。经测试,机械特性硬,手电钻配上此控制器后,能作电动攻丝、板手、螺丝刀等作业,实现一机多用。
A multifunction hand electric drill control using voltage negative feedb- ack and current positive feedback,with protecting devices of current cut-off negative feedback,is proposed.The control proves to be mechanically strong and rigid by testing,and a hand electric drill equipped with it can be used as motordriven tap,wrench,screwdriver,etc.
