Electric Motor Cooling Fan
I have a 2.4kW electric motor in a garden shredder. It has a broken radial
cooling fan that is a push fit onto the rear arbor. I don't think that it is available separately as a spare - only the whole motor. Does anyone know a possible source of replacements? It is about 150mm in diameter, radial because it can be used in both directions and plastic. Fits on a 12mm arbor. Andrew |

It is also a very small shaft for such a relatively powerful motor which might make robbing one from a defunct motor difficult. I managed to get one replaced on a brand new motor that was delivered with a fin missing. If you happen to have a local back street rewind workshop they might have something in the scrap bin from a motor taken to them that was beyond economic repair. Failing that, repair or make a replacement. Bob |

Miles Tools are good on spares, although you haven't said what make. http://www.mtmc.co.uk/Spare-Parts__c-p-0-0-240.aspx You need a fan and maybe a lathe. Any old rubbish will fit in there and probably work OK, but it will need to be securely fastened and well balanced. In extremis, throw the fan away and mount a new fan externally (PC cooling fan etc.). You don't need a specific fan, just to achieve airflow. |

Yes, but beware with pc fans, they run far slower than a lot of mains motors, so similar size wuold produce nowhere near enough cooling. NT |

Andrew Bearing Services,now called Brammer sell fans on there own,so do most of the proper power transmission places. |
