INDUSTRIAL ROBOT SPARE PARTS: The worm drive has a simple, compact, small size and light weight. Simple structure, easy installation and disassembly..
WORM GEAR: If you need more torque or slower output speed, it can be used to replace the 4:1 worm gear that comes standard with the worm gear box. Again, this unit reduces backdrive to almost zero..
NOTE: The worm gear is mounted on a 4.7mm D-shaft diameter. The worm is mounted on a 6mm or 4.7mm diameter D-shaft..
HIGH QUALITY MATERIAL: The worm is made of metal, and the worm wheel is made of bronze, which has impact resistance, high temperature resistance, corrosion resistance and long service life..
PARAMETERS: The gear ratio is 20:1, which is suitable for building industrial robots with various functional shapes..

The EV3 Large Servo Motor is a powerful motor that uses tacho feedback for precise control to within one degree of accuracy. By using the built-in rotation sensor, the intelligent motor can be made to align with other motors on the robot so that it can drive in a straight line at the same speed. It can also be used to give an accurate reading for experiments. The motor case design also makes it easy to assemble gear trains..
