Review on AXI Motor (Gold Line 2217/9D )

I shared some information of axi motor before.

Today, i want to discuss
AXI Gold Line 2217/9D Outrunner Brushless Motor .

I brought
this motor on rcecho.com last weekend.




The high quality and performance of AXI 22xx GOLD LINE motors meant that they were a perfect base for development of the new AXI 2217/xx GOLD LINE. New small and powerfull motor AXI 2217/9D GOLD LINE with rotating case is suitable for aerobatic models up to 800g and for microhelicopters up to 700g. Hardened steel Shaft have 3,17mm diameter and is supported by two large ball bearings wich ensure very good mechanical stability. Thanks to using newest materials this motors achieve in their weight category extremely high efficiency and high load possibility. The optional Radial Mount Sets can be use also with AXI 2217/xx series motors.

Motor Nomenclature
Electric motors manufactured by Modelmotors are marked with name and numbers with slash. Name means type of motor (eg.: AXI - brushless 14-pole outrunner, MiniAC - brushless two-pole inrunner). First two numbers mean diameter of stator and next two numbers lenght of stator in mm. Simplified the bigger diameter and lenght the bigger power of motor. The number behind the slash is winding number. The lower winding number the higher RPM and current capacity.
