How to Choose a Stator

The primary component of stall speed is the angle of the stator.

The smaller the degree of angle the higher the stall speed, the larger the degree of angle the lower the stall. A 35 degree is lower stall than a 32 degree. There is approximately 200 RPM difference with 2 degrees of Angle Change.

The secondary component is the number of vanes.

The more vanes, the more overlap, the more overlap the slower the converter will come out of stall mode. This could be described as how “quick” the converter grabs the motor and starts to load it. For example, if you have a 13 Vane / 30 Degree stator and a 17 Vane / 30 Degree stator, they will both flash stall close to the same, but the 13 Vane / 30 Degree stator will become efficient (load the engine) at a faster rate.
