    • The invention relates to a method for limiting impedance variations of an electromagnetic actuator such as a relay comprising a magnetic circuit. The actuator is made up of a stationary magnetic armature and a moving vane placed against a spring and capable of moving a mechanical actuator element projecting from a box via an opening made in the latter, a permanent magnet suitable for attracting the vane into contact with the armature, and at least one induction coil. The method comprises the following steps: a) closing and maintaining the vane in contact with the armature; b) mounting one or two coils around the armature; c) sending at least one signal with current I to the coil or coils; d) measuring the voltage U at the terminals of the coil or one of the coils; e) measuring the current I in the or the other one of the coils; f) calculating the impedance Zcal = U/I; and g) determining the number of turns to be coiled using a coiling graph showing Nturns = f(Zcal).
