Double Pulley for 1/2 Inch Belts
- For permanent magnet alternators with 17mm shaft
- Pulley fits 1/2" belts

This pulley is used on our PMAs along with a cooling fan when using a gas motor or hydro, a must for keeping your PMA cool! Allowing your PMA to overheat will burn out the stator. A fan and pulley are not necessary when the PMA is being used for a wind turbine.
