    Motor Description

    • YE5 series ultra-efficiency 3 phase asynchronous induction motor should be always stored in the dry, vibration-free and dust-free indoor environment, and should not be stored in the wet warehouse with acid and alkali, rats or other easy corrosive gases. For the motor without being installed temporarily, the machining fitting surface (such as shaft extension and flange) of exposed parts of motor should be coated with anti-rust oil for protection in case of corrosion.
      For the motor without being installed and used for a long term, it is recommended to conduct no-load operation for 5 minutes every 3 months (if the conditions are limited, the rotor of turning gear should no less than 100 rpm) in case of grease or bearing failure caused by precipitation of base oil of lubricating grease.
      For motors not being operated over one year, the grease must be replaced before operation due to the limitation of lubricating grease warranty period. (The bearing of closed bearing should be replaced as per bearing type marked on nameplate.
