Dear Ziemens, motor bearings are designed to withstand a certain axial force. If you flip the motor in vertical position the rotor weight partially charges the capacity of allowed axial forces according fo F = m * g. Additionally some bearings are axially pretensioned having an axial spring mounted internally. In worst case the force of spring and rotor is acting in the same direction and overloads possible axial force even without any external acting force. For that reason we distinguish IM V35 vs. IM B35 vs. IM V15! Please verify respective config manual for further information and proper sizing: https://support.industry.siemens.com/cs/ww/de/view/109744012 especially chapter 3.3 and 3.7! |
