It is presented a motor controller configured to control movement of a motor to a mechanical end position. The motor controller comprises: a motor output configured to control an amount of energy being supplied to the motor; a motor input configured to measure a back electromotive force, EMF, voltage over the motor; and a control unit being configured to control the amount of energy being supplied on the motor output based on back EMF measurements from the motor input when the motor output is in a state of not supplying energy to the motor wherein the control unit is configured to detect an end position of the motor based on changes of back EMF measurements.
A motor controller configured to control movement of a motor to a mechanical end position, the motor controller comprising:
A method for controlling movement of a motor to a mechanical end position, the method being performed in a motor controller and comprising the steps of:
A computer program for controlling movement of a motor to a mechanical end position, the computer program comprising computer program code which, when run on a motor controller causes the motor controller to:
