The ECM 58 Series fan/ motor system, for commercial refrigeration and other air-moving applications, is designed to deliver improved efficiency and quieter operation than shaded-pole motors, says the company. The permanent-magnet, dc design allows the motor to achieve very high efficiency and maintain it over a wide speed range, the company says. The system operates at 20% to 25% efficiency compared to 5% to 10% efficiency of systems equipped with shaded-pole motors, which means up to 300% energy savings, says the manufacturer.
