Action Army 45000R Infinity Motor Short Type

The Action Army 45000R Infinity Motor Short Type is a motor that can be fitted as an upgrade in an AEG and is particularly suitable for high speed builds.

This motor is a 45K motor which makes it extremely suitable for lighter springs such as m90 to m110 in combination with, for example, 13:1 high speed gears.

TPA: 13

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.
