There are 4 Smart Drive magnetic rotor options, 2 options for each of the stator options (36 or 42 pole).
For 36 pole stators you need either the type 3 (0.75 W/rpm) or the type 4 (1.0 W/rpm).
This listing is for the High Power Type 4 (1.0 W/rpm)
This type 4 option is our premium rotor.
All our rotors have been balanced to reduce vibration.
This rotor is suitable for DIY wind turbines with 36 finger pole stators.
This listing is not suitable for 42 pole stators.
