Overview
DSpower DS-S001 and DS-S001M are 3.7–4.2 V DC servo motor options for compact motion-control tasks. Select DS-S001 for a 3.7 ± 0.2 g sub-micro servo with PWM communication, plastic gears, and a coreless motor; select DS-S001M for its separate speed, torque, travel, and weight specifications. Supported uses include robotic mechanisms, RC models, and smart-switch actuation.
Features
- DS-S001: 3.7 ± 0.2 g weight, excluding the lead; ABS case; plastic gear set; coreless motor; PWM communication interface; 28T / Φ3.90 mm output shaft; and ≤1° backlash.
- DS-S001: labeled as a sub-micro servo and described as smaller and lighter than a standard servo.
- DS-S001: three-wire lead with a three-pin connector.
- DS-S001M: L&R angle deviation of ≤6°.
