| 摘要 | A method of setting an air gap between an electromagnetic coil and an armature of an electro-mechanical device to be within a desired range includes applying a sensing signal to the electromagnetic coil and monitoring at least one electrical characteristic of the electromagnetic coil. The at least one electrical characteristic is related to a size of the air gap and the sensing signal. The method further includes moving the armature towards the electromagnetic coil to reduce the size of the air gap and stopping movement of the armature towards the electromagnetic coil when the at least one electrical characteristic indicates the size of the air gap is within the desired range. | ||

| 主权项 | 1. A method of setting an air gap between an electromagnetic coil and an armature of an electro-mechanical device to be within a desired range, the method comprising: applying a sensing signal to the electromagnetic coil; monitoring at least one electrical characteristic of the electromagnetic coil, the at least one electrical characteristic being related to a size of the air gap and the sensing signal; moving the armature towards the electromagnetic coil to reduce the size of the air gap; and stopping movement of the armature towards the electromagnetic coil when the at least one electrical characteristic indicates the size of the air gap is within the desired range. | ||
