APPARATUS WITH MOTOR WINDING RESISTANCE MEASUREMENT AND METHOD FOR CONTROLLING SUCH AN APPARATUS
First Claim
1. An apparatus, in particular for ejecting a fluid,having an electric motor (500), the motor comprising at least one motor winding (506a-d),having a control unit (656) for controlling the motor (500),characterized in thatthe apparatus further comprises an electronic detection circuitry (620) configured to determine an electrical quantity, the electrical quantity being a function of the electric resistance (Rw) of the motor winding (506a-d), andthe control unit (656) is configured to control the motor (500) as a function of the electrical quantity.
