A keybar or clamping bolt with a high-resistivity coating to protect an electric machine. The coating engages the laminations, flanges and frame rings and forms a part of electrical circuits through which harmful eddy currents circulate. One class of eddy currents, viz., core-fault currents, due to edge burrs or insulation defects, are forced to flow through this coating. The high resistance of the coating weakens the fault currents, preventing creation of hotspots that can cause core failure. Such coated keybar is in inexpensive alternative to traditional recoating and / or core-fault detection. Another class of eddy currents, viz., keybar currents, caused by over-fluxing, are also forced to flow through this coating. The high resistance of the coating weakens the keybar currents, so prevents core-end overheating. A coated keybar also allows the machine to operate at higher leading power factor. It also prevents core-decompression hence protects the machine against loose laminations.

The invention also provides substrate processing equipment. The substrate perception component is arranged outside the processing chamber so that the substrate perception component is not influenced by processing fluid.
