Sub-Micro Servo 3.7g (Generic) This generic sub-micro servo is one of the lightest servos we carry, weighing just 3.7 g (0.13 oz) without the lead. It is intended for use between 4.8 and 6 V (i.e. with 4- or 5-cell NiMH or NiCD battery packs). Servo horns and associated hardware are included.
Types of servo motors. Servos come in many sizes and in three basic types: positional rotation, continuous rotation, and linear. Positional rotation servo: This is the most common type of servo motor. The output shaft rotates in about half of a circle, or 180 degrees. It has physical stops placed in the gear mechanism to prevent turning beyond these limits to protect the rotational sensor.
