摘要： An exemplary frequency converter and method are directed to estimating an operation point of a pump when the QH characteristic curve of the pump is known. The frequency converter controls the pump, and a process curve is estimated when a first operation point of the pump is in the nominal range. The process curve defines a head as a function of volumetric flow. A rotational speed of the pump is determined and a QH characteristic curve of the pump is converted to a current rotational speed of the pump based on affinity laws. A second operation point of the pump is estimated by determining an intersection point of the converted QH characteristic curve and the estimated process curve.

摘要： An anti-air-return fan system includes a motor, a driving control circuit, and a rotation judgment circuit. The driving control circuit is electrically connected to the motor. The driving control circuit has a driving signal for driving the motor to rotate according to the driving signal. The rotation judgment circuit outputs a judgment signal to the driving control circuit when detecting that the motor reversely rotate. The driving control circuit executes a braking according to the judgment signal. The driving control circuit drives the motor to operate when the rotation judgment circuit detects that the motor doesn't rotate reversely.

摘要： The fluid flow of a fluid displacement device (100) provided with an electric motor (120) may be set on the basis of a power and control unit (90). Thereto, a power circuit generally comprising an inverter (30), such as a frequency inverter, drives the electric motor (110), particularly with a driving voltage (D1). Voltage and current (A1, A2) in the electric motor (110) are sensed sensorless. Torque and rotation speed of the electric motor (110) are derived from said sensed voltage and current (A1, A2). A fluid flow of the fluid displacement device (110) is estimated in an estimator (15) based on said torque and rotation speed of the electric motor (120) and at least some fluid displacement device characteristics stored in a memory. An operation speed of the electric motor (120) based on said estimated fluid flow is defined and may be transmitted to the inverter (30)
