MAC063C Indramat AC servo motor

MAC063C is the C-length package within the MAC063 legacy analog ac servo motor range. The model prefix fixes the 063 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 MS winding code row documents 2.1 Nm continuous torque at standstill and 4.1 A continuous current at a nominal 3,500 rpm winding. Those values describe that published operating row—not every complete MAC063C part number.

MAC063C overview

MAC063C is the C-length MAC063 servo motor. Baseline dimension A is 185 mm. The complete suffix determines winding, cooling, feedback, shaft and brake choices.

Model-specific technical data

MS winding code manual snapshot

Source: MAC project planning manual, Fig. 3.1, page 42. 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

14 mm 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 standard

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

05

Available speeds

3,500 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 blower
  • Radial blower

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

  • Tachometer feedback
  • Second shaft end or mounted encoder options by type code

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

Holding brake

Match the installed holding requirement

  • Without holding brake
  • 3 Nm holding brake

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