Permanent Magnet Alternator
Fan and Pulley For Permanent Magnet Alternator
Add to Cart:
60MM OD #PFK60B
80MM OD #PFK80B
A LARGE extra heavy duty cooling fan must be used for all engine, hydro and or belt driven systems including vertical axis wind turbine applications. Wind turbines usually have enough air circulation not to require a fan BUT you must determine this fact by testing and observation. Specify your cooling fan kit option at the time of your PMA order. Our PMA's are not fail safe!!! If you over load them they can burn out!!! You as the designer must watch carefully for signs of over heating. We will not warranty any fried PMA's!!!!!!
Notched v-belts run cooler and do not slip as much. A slipping belt can cause bearing stress and heat buildup in the PMA. Read the "heat warnings" below.
The fan and pulley come in two sizes:
2 3/8" (2.36"), 60MM OD pulley for wide 1/2" belts and
3 1/8" (3.14"), 80MM OD pulley for wide 1/2" belts
HEAT WARNINGS: Proper v-belt installation is very important when it comes to getting maximum life and efficiency from your v-belts. Take time to insure that your v-belt pulleys are properly lined up with a strait edge and that they are not worn and cutting into the v-belts. Proper v-belt tension should be set with a v-belt tension tool and reset again after the first week or so of operation to allow for v-belts that stretch, and all v-belts will stretch. Most of the stretching takes place in first hours of operation so it is very important to re check belt tension after the belt has had some run time.
IF you are pulling over 500 Watts (in a non wind turbine installation) without a cooling fan your PMA may over heat! Fan kits are very important to have on ALL high amp applications!!!! Keeping your PMA's cooled, fused and under reasonable loads is the operator's full responsibility. Monitor your PMA for excessive heating in all experimental machinery! Maximum PMA's operating temperature is 350 F. for 100% duty cycle. No warranties on ANY burned out PMA's! They are sold in good working condition, you have to keep them cool and never overloaded regarding amperage draw.
