INRICHTING VOOR HET BESTUREN VAN EEN INDUCTIEMOTOR. |
| 摘要 |
A power factor control system for use with AC induction motors which samples line voltage and current through the motor and decreases power input to the motor proportional to the detected phase displacement between current and voltage to thereby provide less power to the motor, as it is less loaded. |
