Motor of AEG guns is basically the main driving force of every automatic weapons. Thanks to him, AEG guns do not have anywhere push and shot. You can simply pull the trigger in choosen mode SEMI or FULL AUTO.
These DC motors are used most frequently for driving NiCd and NiMH rechargeable batteries on the most common voltage 7.2V - 12V and then modern Li-Pol options of 7.4V - 11.1V. This allows torque to be transferred from the pinion to gears in the gearbox. Axle of motors is divided by round cross section "O" where the the pinion is pressed and semicircular "D" where the pinion is secured by worm of the small hex. Motors are divided into three types according to the length axle and of course according to their parameters for basic, high-speed, high-torque etc.
