5 Brushed Planetary Motors for Robotics applications



A robot is an actuated mechanism programmable in two or more axes with a degree of autonomy, moving within its environment, to perform intended tasks.

Autonomy means the ability to perform intended tasks based on current state and sensing, without human intervention.

Humanoid robots were the only thing which was in concern whenever the term ‘Robot’ was discussed. With the increase in areas of robotic applications, people are now able to differentiate between humanoid and Robots.


‘ Any machine with a mobility system, a programmed instruction and an ability to ease human needs is a Robot .’

The planetary geared motors are always well known for its low backlash and higher efficiency characteristic to meet the higher expectation. The article discusses 5 Brushed Motors using planetary gearboxes which can be used in the robotic application areas requiring high torque and small size motors.

Orange Planetary Motors

Orange planetary motors provide optimum torque and rpm in the geared motors category. The gearbox ranges from providing a continuous torque of 5.5 N-cm to 240N-cm according to the rpm requirement of the application. The rpm of the motor ranges from 10 rpm to 1100 rpm. The geared motors come with an operating voltage of 12 Volts and support base motors like RS-395, RS-555, RS-550 and RS-775. Motor encoders can be added with these motors for application which require precise revolutions.
