Litco inventory record match
MDD112 overview
MDD112 belongs to the MDD Digital AC Servo Motors platform. MDD family represented by broad exact-designation records; verify current stock.
Digital AC servo motors matched by frame, length, nominal speed, feedback, output shaft, brake and connector direction.
The base model identifies a useful frame or product group, but it is not enough by itself to select a replacement. Electrical design, feedback, mechanical interface, brake, cooling, firmware and installed options can all change inside one model group.
Send the full nameplate plus photos of the unit and connections. Litco can route the request toward a verified inventory check, repair evaluation, exchange or a technical follow-up.

Inventory records are a starting point, not a live-stock promise. Litco verifies the complete code, physical unit, condition and current stock before quoting.
Individual MDD112 variants
The final letter is the motor-length and torque package, so each supported variant has a dedicated detail page.
MDD112A
MDD112A is the A length and torque variant within the MDD112 frame.
MDD112B
MDD112B is the B length and torque variant within the MDD112 frame.
MDD112C
MDD112C is the C length and torque variant within the MDD112 frame.
MDD112D
MDD112D is the D length and torque variant within the MDD112 frame.
MDD112 manual-backed identification notes
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.

Use one intake for a repair evaluation, exchange request or replacement search. Describe the failure, capture any display or drive fault, identify the machine and axis, and preserve parameters or application data before removing control hardware.
Other MDD model groups
Use the exact model characters on the label. Neighboring groups can use different frames, power classes, interfaces or mechanical packages.
