The motor is said to be in state of vibration if any part of it experiences displacement in any direction. Standard motors comply with normal class of vibration depending on severity as per IS 12075. “Measurement & evaluation of vibration of Rotating Electrical Machines”. The limits of vibration levels are given below. VIBRATION LEVELS : LIMITS OF VIBRATION SEVERITY IN ROTATING ELECTRICAL MACHINES MEASURED IN STATE OF FREE SUSPENTION * Shaft height H, mm 56 to 132 160 to 225 225 Above 1500 & Above 1500 & Above 1500 & Range of speed 600 to 1500 600 to 1500 600 to 1500 Upto 3000 Upto 3000 Upto 3000 Class of vibration Severity RMS Value of Vibration Velocity, mm/s Normal 1.8 1.8 1.8 2.8 2.8 4.5 Precision A 0.71 0.71 0.71 1.12 - - Precision B 0.45 0.45 0.45 0.71 - - Precision C 0.28 0.28 0.28 0.45 - - * The vibration may be determined in rigid mounting condition but the value of vibration severity shall be agreed by a special agreement between the manufacturer & the user. 12

The motor is said to be in state of vibration if any part of it experiences displacement in any direction. Standard motors comply with normal class of vibration depending on severity as per IS 12075. “Measurement & evaluation of vibration of Rotating Electrical Machines”. The limits of vibration levels are given below. VIBRATION LEVELS : LIMITS OF VIBRATION SEVERITY IN ROTATING ELECTRICAL MACHINES MEASURED IN STATE OF FREE SUSPENTION * Shaft height H, mm 56 to 132 160 to 225 225 Above 1500 & Above 1500 & Above 1500 & Range of speed 600 to 1500 600 to 1500 600 to 1500 Upto 3000 Upto 3000 Upto 3000 Class of vibration Severity RMS Value of Vibration Velocity, mm/s Normal 1.8 1.8 1.8 2.8 2.8 4.5 Precision A 0.71 0.71 0.71 1.12 - - Precision B 0.45 0.45 0.45 0.71 - - Precision C 0.28 0.28 0.28 0.45 - - * The vibration may be determined in rigid mounting condition but the value of vibration severity shall be agreed by a special agreement between the manufacturer & the user. 12
