Do not use a engine power belt to drive your accessories directly off the pilot shaft. Use a industrial wide cog belt that is driven off a independent drive shaft mounted on industrial face mount bearing plates. Then the drive shaft is taper lock couple to the main motor pilot shaft.
This installation prevents the belt force in one direction off the pilot shaft, which will increase the motor bearing wear. No problem using this design for 33 years! I use Dodge Power Transmission engineering design manual that what items to use per what horsepower and torque is needed in drive transmission. What is most important is the belt angles, the size of pulleys and the tangent area of the belt surface to the pulley surface. I also use a soft start torque drive that reduces the starting torque of the main motor which is normally use in large industrial vehicles. This also reduces the start up ampere of the motor.

It started with a tail shaft belt drive for the OEM compressor. The belt drive as initially configured failed to transmit enough torque to drive the compressor reliably. A reconfiguration of the belt geometry had some problem also, I don't remember what. I was unhappy with the belt drive anyway; it made the no clutch configuration difficult to shift. On to a MasterFlux. an electric solution. The MasterFlux had insufficient cooling capacity and failed in short order. I gave up on it and ordered <namebrandforgotten>. Money up front and extremely slow delivery, like a year. These people were seeking OEM business and did not really want to fool with one offs. It ran a few hours, then failed. I have somewhere north of $10k in air conditioning and had a total of less than 5 hours of cooling in about 8 years. My advice on air conditioning: buy an imiev, buy a Tesla, even buy a Leaf. My imiev cost very little more than I expended on the Hyundai air conditioner. And I have good reliable air conditioning on the imiev from day one. _______________________________________________ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub<http://www.evdl.org/help/index.html#usub> http://lists.evdl.org/listinfo.cgi/ev-evdl.org<http://lists.evdl.org/listinfo.cgi/ev-evdl.org> For EV drag racing discussion, please use NEDRA (http://groups.yahoo.com/group/NEDRA<http://groups.yahoo.com/group/NEDRA>) -------------- next part -------------- An HTML attachment was scrubbed...
