Sunon’s EC motors use 70% less energy than conventional AC motors

Written by: Tom Austin-Morgan | Published:

Sunon has released the HVAC 1/3 HP EC (electronic commutated) motor which, it says, features much higher energy efficiency (92%) than conventional AC motors under heavy loading. Compared with an AC shaded pole induction motor, the Sunon HVAC 1/3 HP EC is claimed to reduce energy consumption by 70% and by 40% compared with an AC condensing motor.

Sunon HVAC EC motors are intended for use in the evaporator of commercial refrigeration systems and walk-in coolers and freezers, as well as split system, heat pump and package system outdoor condensers. These low noise motors can also be used for constant airflow indoor blowers.

The EC motors feature an embedded circuit to help limit energy loss, and further benefits include multi-control capability, compact size and extended life thanks to inherent soft-start functionality, brushless technology, lower operating temperatures and high IP protection rating.

Housed in a NEMA 48 motor frame, Sunon’s HVAC 1/3 HP EC motors are able to operate in temperatures from -40 to 60°C, offering a design life of 80,000 hours for evaporator and condenser fan applications.
