EC motor

SUNON HVAC EC motor is a high performance 3 phase permanent magnet motor with brushless structure. With its outstanding electrical commutated technology, the efficiency is much higher than conventional motors under heavy loading.

SUNON HVAC EC motors are designed primarily for use in the evaporator of commercial refrigeration and walk in coolers and freezers as well as split system, heat pump and package system outdoor condensers.
The motor can also be used for indoor constant airflow blower while adjusting the program in the microchip of the motor. Customers will enjoy the high efficiency and energy saving benefits in many residential or commercial HVAC applications.

 


 

▪ Performance of Motor with Constant Airflow Control Mode
Above the maximum Static Pressure, the Constant Airflow control mode won’t be kept,
so it’s a must to pre-determine it based on real pressure change.

※ The performance of SUNON constant airflow control mode is better than famous US company’s.
※ SUNON motor provides lower power consumption.
※ SUNON blower provides higher overall fan efficiency.
