WIRTSCHAFTLICHES GESCHWINDIGKEITSREGELSYSTEM MIT GROSSEM WIRKUNGSBEREICH |
摘要 |
A speed control system is disclosed wherein a brushless DC motor and a magneto resistive encoder are able to rotate a motor at arbitrarily low speeds. The motor is able to rotate at low speeds by having a filtered signal generated by an encoder applied to its inputs. The encoder is coupled to a series of filters which remove DC level and harmonic distortions from the resulting encoder signal. These filtered signals are then applied to the motor to control motor rotation speed. |
