换向器

The direction of electric machinery is the two inverting contactor that outside passing, receives, in control unit control falls, direction of switch of 0 electric current, won't produce alternate with circumfluent.

电机的方向是通过外接的两个换向接触器，在控制单元的控制下，零电流切换方向，不会产生相间环流。

The directional changeover of electric machinery is the two inverting contactor that outside passing, receives, in control unit control falls, switch way leaves in 0 electric current, won't produce alternate with circumfluent.

电机的方向转换是通过外接的两个换向接触器，在控制单元的控制下，在零电流下切换方向，不会产生相间环流。

The automatic valve is equipped with DKJ electric actuator, which receives and adjusts the control sign of DCS, PLC epistasy meter or manual control sign of operating and outputs angle displacement to drive transmission shaft, then drive separating plate rotating with rocker and valve axle.

In my opinion,either the surface of the commutator has become rough and worn,or the coil has been short-circuited.

我看不是换向器表面变粗糙和磨损了，就是线圈短路了。

In my opinion, either the surface of the commutator has become rough and worn, or the coil has been short-circuited.

我看不是换向器表面变粗糙和磨损，就是线圈短路了。

Depending on design, the brushes are connected to external resistances during starting or short-circuited.
