Miniature fan with electronically commutated drive motor - has spring elements preventing transmission of noise between stator and surrounding support frame. |
摘要 |
The fan has a drive motor for rotating fan blades (16) mounted on the rotor. A stator plate (18) is coupled to a support frame (208), via resilient spring elements (30), preventing the transmission of noise. The frame contains at least two strip-shaped reinforcing plates, electrically insulated from one another. The stator frame contains a number of ferromagnetic conductors, electrically insulated from one another, and at different electrical potentials. The conductors are electrically connected to respective reinforcing plates via the spring elements. USE/ADVANTAGE - For monitoring parameter values of air in vehicle passenger space. Low running noise.
