Pneumatic motor success with pneumatic motors in the locomotive industry. In 1911 he designed a pneumatic locomotive and sold the patent to the H.K. Porter Company in Pittsburgh for use in coal mines. Because pneumatic motors do not use combustion they were a much safer option in the coal industry. Many companies claim to be developing Compressed air cars, but none are actually available for purchase or even independent testing. Impact wrenches, pulse tools, nutrunners, screwdrivers, drills, grinders, die grinders, sanders, dental drills and other pneumatic tools use a variety of air motors. These include vane type motors, turbines and piston motors.
Mabuchi Motor is the number of rotations per minute of the motor shaft when voltage is applied between the terminals with no load to the motor. No-load current is the current discharged when voltage is applied between the terminals with no load to the motor. Stall torque is when the motor rotation stalls upon increasing the load to the rotating motor, while stall current is when the motor rotation stalls upon increasing the load to the rotating motor. The physics formula E = M (electrical energy input equals mechanical energy output) demonstrates the conservation of energy principle at work in a Mabuchi
