Rozum Robotics vs. Other Servo Motor Manufacturers
As the servo market continues to expand, more servo motor manufacturers are putting their products out for sale. Traditional leading industry manufacturers belong to producers from North America, Asia, and Europe. The USA, China, and Germany account for over a third of global supplies. Their offers of servo motors vary widely by type, voltage ranges, construction materials, communication protocols, intended use,and various other specifications.
Some of the most widely known servo motor manufacturers include Harmonic Drive Systems, RoboDrive, Kollmorgen, Maxon Motor, Wittenstein, Robotis, and Faulhaber Group.
RDrive servo motors - Power in a compact size
Rozum Robotics has entered the market of servo motor manufacturers with its RDrive series servos. These skillfully designed and superior quality servos feature an integrated controller and a gear head. Designed with proprietary solutions, this compact and lightweight servo produces the same output power and torque that you would find in other larger and heavier servo motor manufacturers products. Even our closest competitor RoboDrive can't beat it!
To produce such a specific and niche product we have contracted with reputable and vetted vendors who share the same high manufacturing standards that we do. Quality materials such as rare earth metals for rotor magnets and electrotechnical steel for stator plates go into making Rozum Robotics RDrive servo motors. In the core of every RDrive servo, these high quality materials go into creating and designing a frameless AC motor and controller designed solely by Rozum Robotics.
Manufacturers comparison chart
In the table below, you can find the specifications of the RD85 servo motors by Rozum Robotics. Check out how we compare to the servos from two other manufacturers—RoboDrive and Harmonic Drive Systems.
Rozum Robotics RDrive 85
Integrated magnetic encoders
|Rated torque, N•m||120||67||108|
|Peak torque, N•m||160||176||157|
|Rotation speed, RPM||40||18||56|
|Gearhead backlash, arcmin||0,3||<1||<1|
|Supply voltage, V||48||48||220 … 430|
|RMS current, A||14.5||11.0||2.2|
|Number of poles||10||10||12|
|Operating temperature, °C||-10 … +45||0 … +40||0 … +40|
As you can see from the table above, the RDrive 85 is still lighter compared to the models manufactured by RoboDrive and HarmonicDrive. At the same time RD85 features highest torque value.
RD50 - the smallest in a series of 4 models - showing great eprformance
A strain-wave gear head with a gearhead ratio of 1:100 allows for high performance and energy efficiency, whereas the backlash of 0.3 arcmin accounts for excellent precision of positioning.
The magnetic technology applied in encoders ensures high-precision motion feedback even in dusty environments and fluctuating work conditions (e.g., vibration, humidity). The operating temperature range is wider than that in the specifications of the other two competitors, enabling its usage below 0°C and above 40°C.
It is obvious to see that the RDrive servo is the best option for those seeking both compact size and high power.
