DEVICE FOR REDUCING FIELD VOLTAGE PEAK OF DC MOTOR |
摘要 |
A circuit arrangement is disclosed for reducing field voltage peaks in direct current motors which are energized by way of an electronic D.C. regulator, and which have an exciter winding connected with the armature and commutating pole windings by means of diodes. The circuit arrangement includes a choke coil connected in series with the exciter winding. In addition, a resistor is connected in parallel with the exciter winding. This arrangement prevents a rapid rise in the field current or the magnetic field flux of the motor. |
