Product information
The 3-speed fan clutch of the LINNIG brand can realize three possible fan speeds, which are each influenced through the input speed.
Speed stage 1: In inactivated condition, the approx. fan speed is 150 RPM.
Speed stage 2: Through activation of the stage 2 electromagnet and with employment of the permanent magnets, a contact-free and wear-free speed of 30 % - 75 % of the input speed can be realized. The respective speed is adapted to customer specifications.
Speed stage 3: The stage 3 electromagnet is activated in order to achieve the maximum rated fan speed. The fan now runs synchronous to the input speed, with no loss of speed.
The signals for the electromagnets either come directly from temperature sensors in the cooling circuit or via the engine-control system. The result is demand-meeting fan engagement.
A mechanical interface, as an example, is the front of the engine. In this section, the clutch also contains the assembly plate as well as the pulley. Further possible interfaces, depending on application, can be the water pump or the crankshaft. When the fan is positioned offset of the engine, the pulley forms the mechanical interface.
Fan sizes for applications range between 300 mm and 1,200 mm.
Among other applications, the 3-speed electromagnetic fan clutches are also used in cooler regions, as the speed stage 1 prevents over-cooling of the engine at minimal fan speed.
