MDD071C Indramat Digital AC servo motor

MDD071C is the C-length package within the MDD071 digital ac servo motor range. The model prefix fixes the 071 frame and C motor length, but the winding, cooling, feedback, centering, shaft, connector and brake fields still determine the complete replacement.

The planning manual’s MDD071C-N-030 row documents 6.6 Nm continuous torque at standstill and 10.8 A continuous current at a nominal 3,000 rpm winding. Those values describe that published operating row—not every complete MDD071C part number.

MDD071C-N-030 manual snapshot

Source: MDD project planning manual, Fig. 7.1, page 64. Nominal winding speed is not a universal maximum usable speed. Match the drive, load, cooling arrangement and complete suffix.

Continuous ratings use the manual’s 60 K housing-temperature-rise basis. Published motor mass excludes the holding brake and external cooling hardware.

Shaft & flange

19 mm (k6) output shaft

Plain shaft and Keyed shaft are documented at series level. Match the flange drawing, shaft seal and hub connection before installation.

04

Centering diameter

95 mm

The centering choice is encoded in the complete part number and must match the machine flange or adapter.

05

Available speeds

3,000 rpm · 4,000 rpm · 6,000 rpm

These are published nominal-speed choices for this model. The winding code and selected drive determine the actual configuration.

Feedback, shaft and brake choices

Configuration choices

Cooling, feedback and holding brake

Cooling

Manage continuous load and machine clearance

  • Natural convection
  • Axial surface cooling
  • Radial surface cooling

External or surface-cooling arrangements can change the installed envelope and are not interchangeable from the model name alone.

Feedback

Keep the drive’s position and speed signal compatible

  • Digital servo feedback
  • Digital servo feedback with integrated multiturn absolute encoder

Photograph the feedback connector and every suffix after the core model.

Holding brake

Match the installed holding requirement

  • Without holding brake
  • 3.0 Nm holding brake
  • 6.5 Nm holding brake

A blocking or holding brake is not a dynamic service brake. Check the published exclusion notes for the exact motor length.
