Double Pulley for 1/2 Inch Belts

  • For permanent magnet alternators with 17mm shaft
  • Pulley fits 1/2" belts

If you have a problem with your PMA overheating it may be a slipping belt causing the problem. On high amp output, the PMA or alternator is under a large load and starts to overheat when the belt begins to slip. That's why high amp PMAs or alternators use dual 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.
