3-speed clutch
Function
When both electromagnet couplings are de-energized,
the fan rotates at up to 100 RPM. When clutch 1 is switched-in, a contact-
and wear-free eddy current system is actuated, causing the fan to rotate
at up to 1.200 RPM. When clutch 2 is switched-in, the fan rotates synchronously
with the drive pulley. |
