EC motors effectively address the need for the highest efficiency and control, while installation remains painless and straightforward. All electronics are now completely integrated within motor housing. The customer simply applies the AC power and either a 0-10V or RS485 control signal. Some EC motors include a controller for a PID closed-loop process control internally on board. An advanced commutation method results in extremely smooth fan operation. In addition, the EC motor performance range has been extended to 4HP (3kW) / 177lb-in. (20Nm).
This new range of EC motors helps to meet tough noise and efficiency specifications for rooftop condensers and air handling units
