Drive - electromagnetic clutch, has followed the traditional cooling fan installation location, the electromagnetic clutch connect directly with Pulley, then a simple mechanical structure (no gear box, without lubricants, without intermediate drive shaft), which by virtue of the unique function of the electromagnetic clutch, in addition to solving the rigid than the fixed-driven, but also better to a certain extent solved the starting torque, preheat a long time, cooling unreasonable, and so on.
