These spindle motors are large-frame AC main spindle motors used in legacy CNC and heavy industrial machining systems, where replacement or service requires precise matching of motor length, mounting arrangement, cooling method, power connection layout, shaft configuration, and feedback system to the original machine design.
Motor frame and length variants ? 2AD184 frame with multiple motor lengths that influence overall dimensions, cooling compatibility, and allowable vibration severity
Mounting configurations ? Flange and flange-with-foot mounting arrangements used in machine tool installations, with defined constraints based on connection position
Cooling methods ? Shaft-mounted blower and forced-air cooling configurations, with cooling selection affecting allowable connection positions and encoder options
Power connection placement ? Defined housing-mounted power connection positions that must align with existing machine layout and cooling components
Power cable exit orientation ? Fixed output direction of the power connection relative to the motor housing and driven shaft
Encoder and feedback systems ? Digital servo feedback and incremental encoder options used for spindle speed and position monitoring in legacy control systems
Drive shaft construction ? Standard drive shaft configurations used for high-load spindle operation, with balance and sealing considerations
Secondary shaft end ? No driven shaft extension on side B for this motor range
Bearing configuration ? Standard bearing arrangement specified for 2AD184 spindle motors
Vibration severity grades ? Defined vibration classes that must match motor length and bearing configuration to ensure spindle stability
