MDD112 / Individual motor model
MDD112B is the B motor-length and torque package within the MDD112 frame. The complete suffix remains necessary to match winding, feedback, centering, shaft, brake, cooling and connector direction.
Historical record · verify stock
The B at the end of MDD112B distinguishes this motor-length and torque package from neighboring variants in the same MDD112 frame. A later letter generally indicates a longer active motor and greater torque capability, but the factory planning data and complete nameplate govern the exact performance.
Use the complete part number to verify the winding, feedback, brake, shaft, centering, cooling and connector configuration before ordering or substituting a motor.
| Motor family | MDD |
|---|---|
| Frame / series | MDD112 |
| Length designation | B · position 2 in this frame's supported model set |
| Cooling | Natural or surface cooling as encoded by the complete part number |
| Feedback | Family-specific feedback or encoder configuration; verify suffix and connectors |
| Shaft and flange | Centering, shaft style and mechanical options must match the nameplate |
| Holding brake | Optional blocking brake field; verify torque and voltage before replacement |
| Availability | 2 units were previously recorded against MDD112B. Verify the exact code, condition and current physical stock. |
The MDD112 is part of the digital AC servo-motor generation designed for intelligent digital drive controllers. The planning manual identifies it for high-precision applications where synchronism matters.
| Supported length packages | A, B, C and D |
|---|---|
| Nominal-speed codes | 015, 020, 030, 040 and restricted 060 combinations |
| Feedback | Digital servo feedback or integrated multiturn absolute feedback |
| Centering options | 130 mm or 180 mm |
| Output shaft | Plain or keyed, as encoded |
| Cooling and brake | Housing/cooling and blocking-brake fields must be read from the suffix |
Compatibility checkpoint: Not every theoretical type-code combination is valid. Verify nominal speed, cooling, feedback, shaft, centering and brake against the complete factory code.
