Guarder Infinite Torque-Up Short Type Motor

The Guarder Infinite Torque-Up Short Type Motor is a motor that gives the standard 18,000 rpm but is strong enough to allow heavier springs to tighten.

This motor can be perfectly used to replace the original motor should it break down. The Infinite Torque-up motor is strong enough to tighten springs like the sp120/MS120 and above. The pinion gear on the motor has had thermal treatment which makes it even stronger and will therefore last longer provided the motor height and gears are correctly shimmed.

TPA: 18

TPA means revolutions per armature. The Armature is the central shaft in the airsoft motor on which the wire is wound. How many times the wire is wound means TPA. So 22 TPA means 22 stacks of wire wound on each side. The more wire, more magnetic field, more torque, but also more weight and less speed. Also, the higher the TPA, the less trouble from overheating.
The higher the TPA, the more Torque, the lower the TPA, the more high speed.
