Feedback 360° 高速伺服器 驅動馬達 高速舵機 伺服馬達

Parallax Feedback 360° 高速伺服馬達概述：

Parallax Feedback 360° 高速伺服馬達集標準伺服馬達、連續旋轉伺服馬達、高速伺服馬達和編碼器的功能於一體，非常方便。這是 ActivityBot 360° 機器人上的伺服馬達，也可作為選配升級用於cyber:bot 機器人。與大多數連續旋轉伺服馬達一樣，Feedback 360° 伺服馬達由 50 Hz PWM信號控制。它的與眾不同之處在於內部霍爾感測器系統的回饋訊號線可提供馬達角度位置回饋。利用該回饋信號，您的應用可使伺服馬達轉到並保持任意角度，與標準伺服馬達類似，但運動範圍不受限制或者以可控制、可驗證的速度（最高 120 RPM）連續旋轉伺服馬達，作為機器人驅動馬達。在整個速度控制範圍內，控制信號回應呈良好的線性關係。

● Bidirectional, continuous, feedback-controllable rotation from -120 to 120 RPM

● PWM positional feedback across entire angular range
● Internal Hall effect position sensor, which is not subject to wear or sensor deadband as are potentiometer-style feedback systems
● No need to manually “center” the servo
● 3-pin ground-power-signal cable plugs onto the Activity Board’s 3-pin header
● Separate single wire with female connector supplies feedback to a separate I/O pin
● Fits our Small Robot Wheel and Tire and Servo Wheels
● Supported by the cyberbot library for micro:bit, and Propeller C libraries and BlocklyProp blocks for the ActivityBot 360° robot
