What Is Commutation? |
|
Answer» The currents in the coils connected to a brush are EITHER all towards the brush (positive brush) or all directed away from the brush (negative brush). Therefore, current in a coil will REVERSE as the coil passes a brush. The REVERSAL of current in a coil as the coil passes the brush axis is called COMMUTATION. The currents in the coils connected to a brush are either all towards the brush (positive brush) or all directed away from the brush (negative brush). Therefore, current in a coil will reverse as the coil passes a brush. The reversal of current in a coil as the coil passes the brush axis is called commutation. |
