Scorpion SII-2215-1810Kv Brushless Motor

Description:

Scorpion SII-2215-1810Kv Brushless Motor

Technical Details:

The new SII-22mm motors have been designed to replace the original S-22mm motors that were introduced in January of 2007.
These new motors include several design improvements that make them more powerful and more efficient than the original S-22mm series.
The design improvements include:

1. New cooling fan design that works equally well in either direction of rotation.

2. New stator design to concentrate the magnetic fields at the pole faces.

3. New stator plate alloy to increase efficiency and reduce heat losses.

4. New flux ring alloy to contain more of the magnetic field within the motor.

5. The higher efficiency of the motor naturally lowers the Kv of the motor, so to get the Kv back up, fewer turns of heavier gauge wire are used.
This lowers the internal resistance (Rm) of the motor and increases the current handling ability.
