EC Motor – Principle 


With an EC motor the electronic circuitry stands in lieu of the traditional mechanical commutation meaning the right amount is being supplied in the right direction at exactly the right time providing precise motor control

AC vs. EC

 

1. 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.

 

Variable speed control of EC fan can be realized / achievedvia 0-10V speed adjustment and/or external circuit impulse modulation

 

Constant torque ,constant speed and constant airflow of EC fan can be fulfilled via 180,sine SVPWM(Space Vector PWM)to meet customer needs

 

Intelligent EC fan can support users to realize centralized operation control by 485 bus and monitor as many as 255 fans

 

 

 

 FAQ

 

1. Are you a factory or trading company?

We are a factory which specialized in produce external rotor motor about 10 years. We accept OEM or ODM

 

2. Can we buy a sample for testing?

Sure, you are welcomed to buy a sample before mass order.

 

 

Why choose us?

 

1. We belongs to the factory, so price we can give is based on factory cost, not trading cost.
