Determining rotary position of commutated DC motor, carries out current ripple spectrum analysis to determine speed and drive shaft position. |
| 摘要 |
The armature current is first analyzed into its spectral components. Rotary speed is then determined from spectral analysis of the updated current ripple frequency in the armature current signal, arising during operation of the DC motor. From the rotary speed, the current position of the motor drive shaft is determined.
