At YS Tech USA, we specialize in providing high-quality centrifugal blowers that utilize EC motor technology. Unlike axial flow fans and blowers that use propellers to move air, our centrifugal blowers use cfd optimized impellers to enhance the volume of the air flow. This results in higher static pressure that can overcome the system resistance caused by electronics, circuit boards, ducts, dampers, and other downstream components. Centrifugal blowers provide radial air displacement, altering the airflow's direction from the input to the output (usually at a 90° angle). This design, combined with our EC motors, provides superior performance for our blowers, even in the most challenging applications.
What are EC blowers and how do they work?
An EC motor, or Electronically Commutated motor, is a type of brushless, direct current, external rotor motor. It uses commutation electronics to convert an AC voltage into a direct voltage. The motor's position is determined by the voltage supplied by an inverter module, similar to the principle used in a frequency inverter. The EC commutation electronics differ from a frequency inverter in that they control how the motor's stator phases are supplied with current (commutation), based on factors such as position, rotation direction, and defaults.
Advantages of EC motor technology
EC motor technology offers several key advantages over traditional brushless DC motors:
-
Higher efficiency: EC motors are up to 30% more efficient than traditional brushless DC motors, resulting in lower energy consumption and operating costs.
-
Better control: EC motors offer precise speed control and position feedback, making them ideal for applications that require high levels of accuracy and repeatability.
-
Lower noise and vibration: The design of EC motors results in lower noise and vibration levels, making them ideal for applications that require quiet operation.
-
Longer lifespan: The absence of brushes in EC motors means they have a longer lifespan than traditional DC motors, resulting in lower maintenance costs.
