RDrive by Rozum Robotics is an all-in-one high torque servo. RDrive servomotor unites in a single housing all the main elements: an encoder, a controller, a harmonic gear and an AC brushless motor. Since the servo controller is integrated into the robot motor, the RDrive is a DC servomotor with a brushless AC core.
Service life of our servo motors is 35,000 hours. Rozum Robotics also provides a 1-YEAR WARRANTY. Our online support team is eager to help you whenever needed. Detailed video instructions and technical documentation for high torque electric motor are provided. Average servomotor lead-time 2-8 weeks. A network of international dealers and distributors for local support is available.
The first RDrive servo motor was created to drive Rozum Robotics collaborative robot that we designed and built completely in house. We were disappointed with the quality of cheap Asian servos and were unwilling to pay for expensive customization in Europe. The factors motivated us to take it upon ourselves to design and create our own robotic actuator.
Most servomotor manufacturers produce a housed brushless motor coupled with an encoder. They call it a servomotor. Powered by DC current, the BLDC motors are controlled with the help of an external servo controller kit (sometimes called servo drive). In case you need a gear motor kit, you connect a gearhead to the motor. The overall design is whatever but not a compact servo motor in this case.
