巴慕达音箱不工作机电传

　　1、Development of electromechanical transmission

　　①

　　Group drag：One motor drags a sky axis，Drag multiple production machines by the air 巴慕达电风扇常见问题 through the transmission

　　②Single motor drag：Drag a production machine with a motor。

　　③Multi-motor drag：Each moving part of a production machine has a special motor drag.（Flexible control）

　　2、Control system development：

　　①Simple contactor-Relay control（Slow speed，Poor accuracy）

　　②Motor amplifier control（Control system has intermittent control to development to continuous control）

　　③High-power controllable rectifier element cryogenate control（Handable silicon）；Easy to achieve rectification（cross—straight）；Reverse（straight——cross）

　　④Computer CNC：（computer technology，Microelectronic Technology，Binding of thyristor technology）
