Erp Certified Ec Plug Blower Pwm Controlled Evaporative Cooler Process Cooling
AC motors are designed to operate at a certain point on their performance curve which coincides with their peak efficiency. Either side of this operating point, the efficiency can drop off considerably. EC motors on the other hand have an almost flat efficiency curve which varies relatively little across the speed range, a range which is not limited by synchronous speeds or as susceptible to voltage fluctuations as an AC motor. This makes the EC fan much more flexible in terms of being able to use the same product to match the performance requirements of different applications while still benefitting from increased efficiency.

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
Enable the selection of different power levels thus to get the best match of price and performance according to customers’load requirements
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
Ec fan exchange air by moving the air in a variety of aquipment and systems, its superiority is not only reflected in the compact structure, low noise and high efficiency but moreover it can keep continuous speed adjustment based on real-time temperature or pressure change, furthermost saving the power
Can we buy a sample for testing?
Sure, you are welcomed to buy a sample before mass order.
What about delivery date?
Product can be sent to you within a week if there is stock after receiving deposit or 100% payment from customer. If there is no stock, the delivery date will be 15 to 30 days.
