Fantom Facts Machine 3S Brushless Stator Resistance & Inductance Meter

This is the Fantom Facts Machine 3S Stator Resistance and Inductance Meter for Brushless Motors. Did you know that knowing the inductance of your motor is just as important as knowing the resistance, yet most racers don't pay much attention to this. Most racers are only concerned with getting the lowest resistance stator they can find, however, this is only half the equation in finding the best stator possible. Inductance also plays a very important role in your motor's performance. The general rule of thumb is the combination of the lowest resistance and highest inductance produces the highest performance for R/C motors, and the difference between these two numbers we call the "spread". Typically, the bigger the spread, the better the motor will perform. For example, using common 17.5 turn numbers of 18.0 milliohms as the resistance number and 30.0 milliHenries as the inductance number, this is a spread of 12. If you could find another 17.5, for example, with a spread of 12.5, this motor will run better o...
