Ideal for making a PMA (permanent magnet alternator) with a Delco 10si or 12si alternator.
Designed for wind turbines and hydroelectric applications with our fan and pulley (sold separately). This rotor has a high amount of "cogging" but translates into a high amount of power. For wind turbine use, we recommend our Falcon five blade set (see recommended items below) for high torque and start-up power. For pulley driven applications, we recommend our 80mm size pulley.
