Sustainable speed control benefits to achieve low operating costs, reduce CO2 emissions protect the environment, enable the direct, simple communication between the host controller and the system,


Variable speed control of EC fan can be realized / achievedvia 0-10V speed adjustment and/or external circuit impulse modulation


 Constant torque ,constant speed and constant airflow of EC fan can be fulfilled via 180,sine SVPWM(Space Vector PWM)to meet customer needs


Permanent-magnet brushless DC motor within the rotor

The stator is driven by electronic switches (which replace the Carbon brushes), controlled by a microcontroller.

Electronic system (hall effect sensor or software is used to recognize the rotor position

EC operated (230Volts Single phase or 380/480Volts , 50/60Hz)


Pressure control : A pressure sensor can be connected directly to the Electronic of the EC motor. The pressure control is made by the integrated electronics. No additional control unit is needed. (Rosenberg Versions only)


How do I know which model I should choose
