Abstract (en)
[origin: EP1710441A2] The method involves using a regulator unit (6) for detecting and estimating the rotor phase position and rotor speed of a PMSM (permanent multi-phase synchronous motor) (3) and for determining fluctuations in the estimated rotor speed for pump operation. The pumping or foam or air is controlled based on the estimated rotor phase position and rotor speed.
