Servomotors RDrive

Featuring integrated controller, encoder, and harmonic gear drive

RDrive by Rozum Robotics is a hollow shaft compact servomotor. A frameless motor, 2 absolute position magnetic encoder,  a strain-wave gear and a motor controller are all placed in a single housing. Though RDrive is a small servomotor (53-115 mm diameter), it can boast high torque density (up to 333 Nm), high power (up to 680 W), and high precision (0.01 mm).

AC or DC 

Most servomotor manufacturers produce a housed brushless motor coupled with an encoder. They call it a servomotor. Powered by DC current, the motor is 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. 

RDrive servo by Rozum Robotics is an all-in-one solution. 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 controller is integrated into the motor, the RDrive is a DC servomotor with a brushless AC core.
