By propelling the air with its rotor blades, also known as banes, the motor creates the power that is transmitted through the rotor. This rotor works in conjunction with the planetary gear system to convert the rpm’s from the tool and while creating torque and power reduces the RPMs to the chuck. The planetary gear is essentially the speed reduction and power multiplier mechanism. A pneumatic drill, much as most air tools require of an air motor with parts such as rotor, rotor blades, cylinder, upper and lower plates as well as bearings. These assembled parts work together to bring life to the tool.
