2AD100/2AD104 spindle motors are legacy AC main spindle motors commonly encountered in existing CNC and industrial machines, where replacement or service requires matching mechanical dimensions, mounting style, power connection orientation, and feedback configuration to the original installation.
Motor frame and length variants ? 2AD100?104 frame with multiple motor lengths that affect overall dimensions, cooling compatibility, and allowable vibration class
Mounting configurations ? Flange-mounted (B05) and flange-and-foot (B35) designs used in legacy machine tool installations
Power connection placement ? Left, top, or right housing-mounted power connections, which must match existing machine layouts and cooling arrangements
Power cable exit orientation ? Defined output direction of the power connection to ensure compatibility with enclosure clearances and cable routing
Encoder and feedback systems ? Digital servo feedback, incremental encoders (2500 increments), and integrated singleturn or multiturn absolute encoders, including variants used in hazardous-area systems
Drive shaft construction ? Plain or keyed shafts with balanced options and optional shaft sealing rings, critical for mechanical interchangeability
Secondary shaft end ? No shaft extension on side B for this motor size range
Bearing configuration ? Standard bearing arrangement consistent across 2AD100?104 motors
Vibration severity grades ? Specified vibration classes that must align with the original motor length and machine spindle requirements
