What 1MB240 identifies
The 1MB240 technical table separates three length packages with distinct torque and power values. The type-code chart also ties rotor-bore availability to particular lengths, making the full 1MS and 1MR designations essential for a mechanical match.
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
1MB240 questions
Before Litco pulls a unit
Is 1MB240 enough information to order a replacement?+
No. 1MB240 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 1MB240 fields should I compare first?+
Start with complete 1ms stator and 1mr rotor codes; frame length, winding and rotor-bore combination; liquid-cooling circuit and thermal monitoring. Then preserve the remaining suffix, material number, revision and every installed option or firmware label.
Where is 1MB240 equipment commonly used?+
1MB240 is documented for direct-drive machine-tool spindles, turning, milling and grinding machines, transfer lines and processing centers, special-purpose production machines. The installed machine, axis and connected equipment still control the final replacement decision.
Can Litco evaluate a failed 1MB240 unit?+
Yes. Litco can discuss replacement, repair and exchange paths after reviewing the complete code, application and failure information.
