<p>The Application Case II relates to a subsequent design which is characterized in by that, the shunt or series winding of the motor-generator is further employed as an auxiliary exciting winding to replace the auxiliary winding in the former application case. It is aimed to economize the production cost and reduce the occupation of the winding inside the motor-generator chamber so as to promote its efficiency. With a control interface we may control output voltage or output impedance from the auxiliary generator for controlling output current and further selecting assisted magnetizing or differential magnetizing of aforesaid main motor-generator auxiliary field winding against the main field; the present dynamic current feedback magnetizing type series or compound DC motor-generator control circuit is also applicable to a generator or dynamo motor, which may replace expensive magnetic saturation amplifier or other complicated solid and dynamo switch loop to become an independent dynamo, endurable and reliable control system.</p> |
