Air-Conditioning Fans Ebm Papst Zx254n-24d3-02 New Energy
1． Brushless DC external rotor motor belongs to non-mechanical
brush(commutator)DC motor which enforces the winding current
commutation through electronic commutator (position sensing,
non-position sensing),achieve the speed control function with PAM
or PWM control
2． Enable the selection of different power levels thus to get the
best match of price and performance according to customers’load
3． As the rotor is mounted to interior, the external rotor fan is
more compact constructed, smaller and easy to abstract heat., thus
ensure to maximum the reliability of fan operation,
4． Sustainable speed control benefits to achieve low operating
costs, reduce CO2 emissions protect the environment, enable the
direct, simple communication between the host controller and the
5． Variable speed control of EC fan can be realized / achievedvia
0-10V speed adjustment and/or external circuit impulse modulation
1.if the fans doesn't work well, what shall I do ?
If happens within one year, we will take in charge of the
maintenance, or send you a new machine freely.
If after one year, we will supply you the right parts to replace at
5. What about delivery date?
