Siemens AG 2008AC motorsOverviewTechnical definitions4/5 Siemens pm 21 20084 Radial eccentricity tolerance, shaft and flange accuracy (concentricity and axial eccentricity) in accordance with IEC 60072 Radial eccentricity tolerance of shaft in relation to housingaxis(refers to cylindrical shaft extensions)Concentricity and axial eccentricity tolerance of theflange surface to the shaft axis(referred to the centeringdiameter of the mounting flange) Vibration severity and vibration magnitude Grade A according to DIN IEC 60034-14 The vibration severity is the RMS value of the vibration velocity(frequency range from 10 to 1000 Hz).

8 The vibration severity ismeasured using electrical measuring instruments in compliancewith DIN values indicated refer only to the motor . These values can in-crease as a result of the overall system vibrational behavior dueto severity limit values for shaft heights 20 to 132 The speeds of 1800 rpm and 3600 rpm and the associated limitvalues are defined in accordance with IEC 60034-14. Speeds of4500 rpm and 6000 rpm and the specified values are defined bythe motor magnitude Grade AThe motors maintain vibration magnitude Grade A up to severity limit values for shaft heights 160 to 280 Shaft heightStandard NOption Rmm (in)mm (in)28, ( ) ( )48, 63, ( ) ( )80, 100, ( ) ( )160, 180, ( ) ( ) ( ) ( )LL/2motormotor shaftdial gaugeTest: radial eccentricityG_DA65_EN_00063 Shaft heightStandard NOption Rmm (in)mm (in)28, 36, ( ) ( )63, 71, 80, ( ) ( )132, 160, 180, ( ) ( ) ( ) ( )10 mm10 mmmotor shaftmotor shaftmotordial gaugedial gaugemotorTest: axial eccentricityTest.

10 The following different balancing methods are used onmotors of types 1PH4, 1PH7 and 1PL6: Half-key balancing Full-key balancing Plain shaft extensionThe balancing method is encoded in the order designation for1PH7 and 1PL6 motors. The letter "H" (half key) or "F" (full key) isprinted on the shaft extension face to identify a half-key bal-anced or a full-key balanced , 1FT6 and 1FT7 motors with fitted key are always general, motors with a plain shaft are recommended for sys-tems with the most stringent vibrational quality requirements. Forfull-key balanced motors, we recommend belt pulleys with twoopposite keyways, but only one fitted key in the shaft extension. Vibration stress, immitted vibration valuesThe following maximum permissible vibration stress limits at fullfunctionality apply only to 1FK7, 1FT6, 1FT7, 1FS6 and 1FW3permanent-magnet synchronous stress (in accordance with DIN ISO 10816): 1g(20 Hz to 2 kHz)The following limits are valid for (immitted) vibration values intro-duced externally to all asynchronous motors of type 1PH7, 1PH4and 1PL6:The following limits are valid for (immitted) vibration values intro-duced externally to all torque motors of type 1FW3.
