High Speed Continuous Rotation Servo

Parallax's High Speed Continuous Rotation Servo offers easily controlled bi-directional rotation via simple pulse-width modulation.  With about 3 times the RPM of the original Parallax Continuous Rotation Servo, it makes an excellent drive motor for small, zippy robots.
 

Key Features:

• Bidirectional continuous rotation, from 0 up to 180 RPM.
• Linear response to pulse-width modification for easy ramping.
• 6 to 8 VDC input range is compatible with 5-cell AA battery packs.
• Accepts four mounting screws, and fits easily into our small robot chassis.
• Access port for adjusting "idle" pulse width.
   

Application Ideas:

• Small robots with precise motion control.
• Replacement for low RPM DC motors.
• Hyper accurate positioning.
