ZCI Neodymium Motor

TPA stands for Turns Per Armature. A 22 TPA configuration prioritizes high torque over raw speed, meaning you will experience a snappier trigger response and the ability to pull heavier springs more easily compared to a standard motor.

This is a 'Long' type motor, which is the standard size for most M4, M16, and MP5 style AEGs. Please check your current motor type before purchasing, as some platforms, like AKs or G36s, often require a 'Short' type motor.

Yes, this motor is fully compatible with 11.1V LiPo batteries. The high-torque design handles the increased voltage well, providing excellent responsiveness without the excessive heat buildup often seen in high-speed motors.

While this motor is a great standalone upgrade for trigger response, it is designed to handle high-stress builds. If you are pairing it with a very heavy spring or high-speed gear set, ensure your gearbox is properly shimmed and your wiring can handle the increased current draw.

Neodymium magnets are significantly stronger and more efficient than standard ferrite magnets. They allow the motor to reach peak torque faster and maintain consistent performance even under the heavy load of a high-tension spring.
