movable in relation to a base, a first electric motor for moving the element in relation to the base, the motor having one or more first windings each having at least two inputs, a first braking element being adapted to determine whether power and/or signals are provided to the first motor and being adapted to alter between at least two modes wherein, in a first of the modes, no power/signals is/are provided to the first motor and a first galvanic connection is provided between the inputs of at least one of the first windings and a first element having a predetermined resistance and wherein in a second of the modes, power/signals is/are provided to the first motor and the first galvanic connection is disconnected. ## Claims ### Claim 1 An assembly comprising: a movable element

no power/signals is/are provided to the second motor and a third galvanic connection is provided between the inputs of at least one of the second windings and a second element having a predetermined resistance and in a second of the modes, power/signals is/are provided to the second motor and the third galvanic connection is disconnected. ### Claim 4 (depends on 3) An assembly according to claim 3, further comprising a controlling element adapted to determine if a braking element is in the first mode and, if so, bring at least one other braking element into its first mode. ### Claim 5 (depends on 4) An assembly according to claim 4, wherein the controlling element is adapted to, before bringing the other braking element into its first mode, operate the motor pertaining to the other braking element to a predetermined position. ### Claim 6 (depends on 1) An assembly according to claim 1, wherein the movable element is an antenna. ### Claim 7 A method of operating an assembly comprising: moving an element relation to a base using a first electric motor having one or more first windings each having at least two inputs, a first braking element being adapted to determine whether power and/or signals are provided to the first motor and being adapted to alter between at least two modes wherein: in a first of the modes, no power/signals is/are provided to the first motor and a first galvanic connection is provided between the inputs of at least one of the first windings and a first element having a predetermined resistance and in a second of the modes, power/signals is/are provided to the first motor and the first galvanic connection is disconnected. ### Claim 8 (depends on 7) A method according to claim 7, wherein the moving step comprises a driving apparatus providing the power and/or controlling signals to the motor via a second galvanic connection, and wherein, in the first mode, the second galvanic connection is disconnected and, in the second mode, the second galvanic connection is provided. ### Claim 9 (depends on 7) A method according to claim 7, wherein the moving step comprises moving the element in relation to the base also using a second electric motor having one or more second windings each having at least two inputs, the method comprising the further step of a second braking element being adapted to determine whether power and/or signals are provided to the second motor and being adapted to alter between at least two modes wherein: in a first of the modes, no power/signals is/are provided to the second motor and a third galvanic connection is provided between the inputs of at least one of the second windings and a second element having a predetermined resistance and in a second of the modes, power/signals is/are provided to the second motor and the third galvanic connection is disconnected. ### Claim 10 (depends on 9) A method according to claim 9, further comprising the step of determining if a braking element is in the first mode and, if so, bringing at least one other braking element into its first mode. ### Claim 11 (depends on 10) A method according to claim 10, wherein the determining step comprises, before bringing the other braking element into its first mode, operating the motor pertaining to the other braking element to a predetermined position. ### Claim 12 (depends on 7) A method according to claim 7, further comprising using the movable element as an antenna.
