Series overview
What 2AD164 identifies
The 2AD164 type code distinguishes mounting, connection direction, axial or radial blower arrangement, winding, brake, motor encoder, shaft, bearing and vibration options. Some explosion-hazard feedback codes require the documented E cooling mode and a shaft sealing ring, so the complete code must be checked as one configuration.
Ratings, connections, feedback, braking and mechanical options vary by complete type code. Send Litco Automation a clear nameplate photo so the exact configuration and compatible replacement can be confirmed.

Series questions
2AD164 questions
Before Litco pulls a unit
Is 2AD164 enough information to order a replacement?+
No. 2AD164 identifies the series group, but the complete type code still carries the winding, cooling, feedback, mounting, shaft, brake and mechanical options that determine compatibility.
Which 2AD164 fields should I compare first?+
Start with complete 2ad frame, length and winding code; natural or forced-air cooling arrangement; motor feedback or encoder configuration. Then preserve the remaining suffix, material number, revision and every installed option or firmware label.
Where is 2AD164 equipment commonly used?+
2AD164 is documented for machine-tool main spindles, printing and converting machinery, production-machine drives, asynchronous servo and spindle applications. The installed machine, axis and connected equipment still control the final replacement decision.
Can Litco evaluate a failed 2AD164 unit?+
Yes. Litco can discuss replacement, repair and exchange paths after reviewing the complete code, application and failure information.
