Abstract: The pinch detector is suitable to detect a pinch at a closing member actuated by a motor equipped with a measuring circuit to measure a motor current. It includes a first portion that, when the motor starts closing the member, obtains a reference value of the motor current measured at the end of a blind time period having a predetermined duration from the moment the motor starts to close the member; a second portion that compares current values of the measured motor current to a threshold value depending on said reference value, during a detection time period, following the blind time period and preceding a steady state time period of the motor, in order to detect a pinch at the closing member based on a comparison result.

Abstract: A method for determining a movement of a rotor of an electric motor, comprises supplying a drive signal to a drive coil of the electric motor, sensing a coil current of the drive coil, detecting current ripples of the sensed coil current caused by the rotor of the electric motor crossing ripple generating positions, inferring the movement of the rotor from the detected ripples, braking the motor by reducing the drive signal supplied to the drive coil from an initial signal value to zero according to a braking curve specifying a non-zero fall time during which the drive signal is reduced from the initial signal value to zero. The braking curve is adapted so that the rotor does not cross a ripple generating position after the drive signal has been reduced to zero.

Abstract: The pinch detector includes a first portion that, in a first situation in which the member is being closed in a first closing movement but is stopped in an intermediate position not completely closed, obtains a reference value of a measured physical quantity of the motor, when braking the motor is ordered to stop the member, said reference value representing the physical quantity of the motor just before motor braking; a second portion that, in a second situation following the first situation and in which the member is moved in a second closing movement from said intermediate position not completely closed, compares current values of the measured physical quantity of the motor to a threshold value depending on said reference value in order to detect a pinch at closing member based on a comparison result.
