RDS51150-12V 150kg 3-Pole High-Torque Digital Servo – Double Bearing – 180 Degree – Red
At 10V, the servo provides a no-load speed of 0.24 sec/60° with 125 kg-cm stall torque; at 12V it reaches 0.21 sec/60° with 142 kg-cm stall torque; and at 12.6V it reaches 0.19 sec/60° with 150 kg-cm stall torque. Position control uses a PWM interface with a 500-2500 µsec pulse-width range, 1500 µsec neutral position, 3 µsec dead-band width, and 50-330 Hz operating-frequency range.

Description
RDS51150-12V 150kg Robot Digital Servo - 180 Degree
The RDS51150-12V is a high-torque 12V robot digital servo designed for demanding robotic positioning and mechanical motion-control applications. It operates from 10V to 12.6V and delivers up to 150 kg-cm stall torque at 12.6V. Its 357 gear ratio, double-bearing construction, and 3-pole motor provide a robust drive arrangement for applications requiring very high output torque.At 10V, the servo provides a no-load speed of 0.24 sec/60° with 125 kg-cm stall torque; at 12V it reaches 0.21 sec/60° with 142 kg-cm stall torque; and at 12.6V it reaches 0.19 sec/60° with 150 kg-cm stall torque. Position control uses a PWM interface with a 500-2500 µsec pulse-width range, 1500 µsec neutral position, 3 µsec dead-band width, and 50-330 Hz operating-frequency range.
