These spindle motors are mid-frame AC main spindle motors used in legacy CNC and industrial automation systems, where replacement or service requires careful matching of mechanical dimensions, mounting configuration, power connection layout, cooling method, and feedback system to the original motor.
Motor frame and length variants ? 2AD134 frame with multiple motor length options affecting overall dimensions, cooling compatibility, and vibration limits
Mounting configurations ? Flange (B05) and flange-with-foot (B35) mounting arrangements commonly used in machine tool installations
Cooling methods ? Shaft-mounted blower, axial blower, or radial blower configurations, with specific restrictions based on motor length and connection layout
Power connection placement ? Left, top, or right housing-mounted power connections, with placement constrained by mounting style and cooling method
Power cable exit orientation ? Defined output direction of the power connection to match enclosure clearances and existing cable routing
Encoder and feedback systems ? Digital servo feedback, incremental encoders, and integrated singleturn or multiturn absolute encoders, including configurations used in hazardous-area applications
Drive shaft construction ? Plain or keyed shafts with balanced options and optional shaft sealing rings, critical for mechanical interchangeability
Secondary shaft end ? Shaft end on side B available or omitted depending on configuration
Bearing configuration ? Standard bearing arrangements used across the 2AD134 motor range
Vibration severity grades ? Multiple vibration classes specified, with higher grades limited to specific motor lengths and cooling configurations
