  • Publication number: 20150037169
    Abstract: 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.
