Zusammenfassung: | An electric breast pump (10) is provided that includes a vacuum source (100) having a vacuum pump (120) with a motor (121), and an inflation valve (150). Further, the controller (110) controls operation of the vacuum (120) and the inflation valve (150). Each breast pumping cycle comprises a breast pumping period (PP) of the vacuum pump (120) and an inflation period (AP) during which the inflation valve (150) is open and the vacuum pump (120) is inactive and the motor (120) is closed. The drive circuit provides a motor supply voltage for the motor (121) under the control of the controller (110). The drive circuit (140) detects an electromotive force induced voltage at the motor (121) when the motor power supply voltage is turned off. The controller adapts control of operation of the vacuum pump (120) based on the detected induced voltage.
