A PSC motor is a commonly used motor that runs at either single or variable speeds, while an EC motor is much more energy-efficient and features an internal smart board offering better motor control. Using EC motors holds three clear advantages over the use of PSC motors. Advantages of EC ...
then it increases power to maintain the same torque. A constant torque ECM will maintain more airflow, than a PSC motor when there is air restriction in the system from dirty air filters from lack ofmaintenanceor ducts. Constant
An automatic torque correction method of an ECM motor used for replacing a PSC motor. The method comprises: Step 1) obtaining, through calculation, torque data corresponding to a high-gear rotation speed group and a low-gear rotation speed group, and storing the torque data in a micro-...

(PSC) or Shaded Pole] and a compatible TRIAC control may be the way to go. TRIAC controls also tend to be more energy efficient at higher speeds than VFDs. Drawbacks of this technology include relatively high minimum speeds and potentially nonlinear control curve (input signal vs. motor speed...
