High efficiency, energy-saving and simple control by 0-10V/PWM signal, widely used in refrigeration units and HVAC

What is an EC Motor?

EC motor are DC motors that function using a built-in inverter and a magnet rotor, and as a result are able to achieve greater efficiency in air-flow systems than some kinds of AC motors. (Although AC current is used for EC motor, the EC's internal rectifier converts the current to DC voltage). Permanent split capacitor (PSC) motors, often used in conjunction with electronic SCR motors, are somewhat inefficient when used in air control systems because the fan motor noise requires the motor to run at less than a full load. When turned down, PSC efficiency suffers and falls in the range of 12 to 45 percent. ECMs, on the other hand, maintain a high level (65 to 75 percent) of efficiency at a variety of speeds. As a result, EC motors are cost and energy efficient and can reduce operating costs. Additionally, EC motors are not prone to overheating and do not require additional measures to offset the generation of heat, as PSCs often do.
