Product Description


365x90mm DC Axial Exhaust Fan for Ventilation System


 


PBM Motor and Fan is a China mainland manufacturer and EC technology consulting company offering an extensive range of EC(Electronically Commutated) motors, fans and solutions, investing in the latest developing, manufacturing and technical equipment with in-depth processes & procedures. Our main products are EC fans, including EC axial fans, EC centrifugal fans and EC blowers. We do both AC and DC current type. And EC Motor is the core technology of our products.


 


Eletronically Commutated Motors(EC Motors)also known as Brushless DC Motors(BLDC) are synchronous electric motors powered by direct-current(DC) electricity and having electronic commutation systems,rather than mechanical commutators and brushes.The current-to-torque and voltage-to-speed relationships of BLDC motors are linear.


 


PBM fans are widely used in many fields. For example, axial fan for telecom, backward curved centrifugal fan for air exchanger,(inline duct fan)hydroponic products and FFU, forward curved centrifugal fan for air purifier and air conditioning,blower for kitchen.

 3. Electrical Protection































3-1



Locked-rotor Protection



Over-current limiting circuit protects motor from damage at least for 72 hours of locked rotor condition at rated voltage.



3-2



Maximum Current


under Locked Rotor


 


 



A, Typical inrush current when the motor is trying to re-start under locked rotor conditions is 2~4 times the normal running current reoccurring and for 16~20% of restarting cycle period.


B, If he CL function is used this restarting inrush current is about the same as the normal running current.



3-3



Reverse Polarity Protection



No damage if the positive and negative leads are reversed under maximum operation voltage conditions.



3-4



Over Voltage Protection



The circuit will be shut down automaticlly when input voltage over 60VDC. And re-started when Voltage down to 60VDC below.



3-5



Soft Start



In 5 seconds after power on and speed control voltage gets to 1.5V or PWM duty cycle at 10% above.
