<p>The rotor R can be rotatably mounted in a support and at least one permanent magnet (21 or 22), which is a temporary or permanent magnet, is arranged adjacent the rotor R rotatably mounted in the support. A rotating means (8), for example an electric motor, in use, rotates the rotor R. The torque applied to the rotor R is monitored to detect any electrical fault in the winding of the rotor R which fault results in an abnormal variation in the applied torque. <IMAGE></p> |
