    The Reliability dashboard displays calculations that are based on data collections and inputs for each configuration tab.

    Tab Section Property Goal Minimum (if applicable) Maximum (if applicable)
    Properties Motor Type Specify as an alternating current (AC) induction or synchronous, direct current (DC), or variable frequency drive (VFD).    
    Synchronous Speed (RPM) Define the nameplate synchronous speed.    
    Full Load Speed (RPM) Define the nameplate full load speed. 1 3600
    Rated Voltage Define the nameplate voltage. 0.1  
    Full Load Amps Define the nameplate full load amps. 0.001  
    Nominal Frequency Specify whether the nominal frequency is 60 Hz, 50 Hz, or VFD.    
    Power Factor Define the nameplate power factor. 0.01  
    Winding Type Specify as Wye or Delta.    
    Insulating Rating Specify a rating for the insulation.    
    Number of Poles Define the number of poles. 2 1000
    Number of Rotor Bars Define the number of bars. 1 1000
    Drive End Bearing Drive End Bearing Type Specify whether the drive end bearing is a sleeve or rolling element type.    
    Lubrication Seal Is Installed Specify whether the lubrication seal is installed.    
    Lubrication System Specify whether the lubrication system is a pumped lube oil, oil bath/splash, grease, or process liquid type.    
    Non-Drive End Bearing Drive End Bearing Type Specify whether the drive end bearing is a sleeve or rolling element type.    
    Lubrication Seal Is Installed Specify whether the lubrication seal is installed.    
    Lubrication System Specify whether the lubrication system is a pumped lube oil, oil bath/splash, grease, or process liquid type.    
    Thrust Bearing Thrust Bearing Specify whether the thrust bearing is installed.

    If installed, specify whether the thrust bearing is the drive end, non-drive end, or separate.

    If separate, specify the location, type, faces, and number of faces of the thrust bearing.
    Minimum number of faces for separate, tilt-pad-type thrust bearings: 3 Maximum number of faces for separate, tilt-pad-type thrust bearings: 30
    Cooling Motor Drive-End Cooling Fan Blades Define the number of fan blades that cool the motor drive-end. 3 30
    Motor Non-Drive-End Cooling Fan Blades Define the number of fan blades that cool the motor non-drive-end. 3 30
    Cooling Air is Filtered Specify whether the cooling air is filtered.    
    Cooling Air is Cooled by a Heat Exchanger Specify whether cooling air is not cooled, cooled by fresh water, or cooled by sea water.    
    Motor Windings have a Space Heater to Prevent Condensation Specify whether there is a space heater for the motor windings.
