It typically creates 2\u00d7 line-frequency vibration (static eccentricity) or 1\u00d7 vibration with pole-pass sidebands (dynamic eccentricity) and accelerates bearing wear through that positive-feedback loop. The remedy is to replace worn bearings, correct any frame distortion, and verify rotor concentricity.<\/p>\n<h3>\u0926\u094d\u0930\u0941\u0924 \u0928\u093f\u0926\u093e\u0928 \u0938\u0902\u0926\u0930\u094d\u092d<\/h3>\n<table border=\"1\" style=\"width:100%; border-collapse:collapse;\">\n<tr>\n<th>\u0932\u0915\u094d\u0937\u0923<\/th>\n<th>\u0938\u0902\u092d\u093e\u0935\u094d\u092f air-gap \u0938\u092e\u0938\u094d\u092f\u093e<\/th>\n<\/tr>\n<tr>\n<td>\u0909\u091a\u094d\u091a 2\u00d7 line-frequency vibration<\/td>\n<td>eccentric gap, unbalanced magnetic pull<\/td>\n<\/tr>\n<tr>\n<td>Pole-pass frequency sidebands<\/td>\n<td>\u0905\u0938\u092e\u093e\u0928 \u0917\u0945\u092a<\/td>\n<\/tr>\n<tr>\n<td>\u0909\u091a\u094d\u091a \u0928\u094b-\u0932\u094b\u0921 \u0915\u0930\u0902\u091f<\/td>\n<td>\u0905\u0924\u093f\u0930\u093f\u0915\u094d\u0924 \u0917\u0945\u092a<\/td>\n<\/tr>\n<tr>\n<td>\u0915\u092e\u0940 \u092a\u094d\u0930\u093e\u0930\u0902\u092d\u093f\u0915 \u091f\u0949\u0930\u094d\u0915<\/td>\n<td>\u0905\u0924\u093f\u0930\u093f\u0915\u094d\u0924 \u0917\u0945\u092a<\/td>\n<\/tr>\n<tr>\n<td>rubbing \u091a\u0947 \u092a\u0941\u0930\u093e\u0935\u0947<\/td>\n<td>\u0905\u092a\u0941\u0930\u0940 \u0917\u0945\u092a \u0915\u094d\u0932\u093f\u0905\u0930\u0928\u094d\u0938<\/td>\n<\/tr>\n<tr>\n<td>\u0905\u0938\u092e\u092e\u093f\u0924 \u092c\u0947\u0905\u0930\u093f\u0902\u0917 \u0918\u093e\u0938\u0923\u0947<\/td>\n<td>UMP \u0928\u093f\u0930\u094d\u092e\u093e\u0923 \u0915\u0930\u0923\u093e\u0930\u093e \u0935\u093f\u0915\u0947\u0902\u0926\u094d\u0930\u093f\u0924 \u0917\u0945\u092a<\/td>\n<\/tr>\n<\/table>\n<h2>7.
