<p>the method involves measuring the inductance of sensor coils (3,5), which are connected to an electronic circuit. The inductance of the first sensor coil depends on the position of the armature plate (1). The inductance of the second armature coil is substantially independent of the armature plate position. The coil cores are thermally well coupled together; the brake lining wear is derived from the change in sensor coil inductances : An independent claim is also included for an electromagnetically operated brake for electric motors.</p> |
