The EV3 Medium Servo Motor is great for lower-load, higher speed applications and when faster response times and a smaller profile are needed in the robot′s design. The motor uses tacho feedback for precise control within one degree of accuracy and has a built-in rotation sensor. - Tacho feedback to one degree of accuracy - 240-250 RPM - Running torque of 8 N/cm (approximately 11 oz/in) - Stall torque of 12 N/cm (approximately 17 oz/in) - Auto-ID is built into the EV3 software
