Understanding Indramat MAC Motors

3 October, 2023


Indramat MAC motors are AC servomotors that are referred to as legacy motors. This is because the manufacturer is no longer making these motors. They are used along with a drive controller from the same manufacturer to function like a rapid-response servo drive. These motors encompass a laminated core with permanent magnets to support electronic commutation.

MAC motors are always associated with tacho feedback for recognizing the position of the rotor and evaluating the speed per tacho generator. They can be additionally mounted with an encoder if needed for position evaluation.  These motors can deliver maintenance-free operation because of their lifetime lubricated bearing and brushless design along with IP 65 degrees of protection.  They are characterized by high output data such as performance, cyclic load capacity and power-to-weight ratio.

The AC servomotors have a rugged housing and can be mounted in any orientation. They encounter axial and radial forces during operation. MAC motors come with or without a holding brake and are equipped with either a plain shaft or a shaft with a keyway, depending on the shaft-hub-connections. They are available in different sizes. MAC motors have separate flanged sockets with connectors on their housing to connect the power, encoder and tacho feedback cables directly.

Applications of MAC Servomotors

MAC servomotors are used in a wide range of applications to meet varying demands. Some major applications of these motors are listed below.

  • Machine tools
  • Transfer facilities
  • Textile machines
  • Handling equipment
  • Printing presses
  • Robotics
  • Packaging machinery

They should not be used for highly demanding applications such as press feeds, pressing and punching unless they are mounted in a shock-decoupled or a shock-damped manner.


What drive controller can the MAC servomotor be used with?

The MAC servomotor can be used with a drive controller of the DSC, KDS or TDM series from its manufacturer. The motor is not compatible with a drive controller from any other manufacturer.

What are the ambient operating conditions of the MAC servomotor?

The MAC servomotor features an ambient operating temperature range of 0 °C to 45 °C and an installation elevation of 1000 meters above sea level. The operating temperature and installation altitude should not exceed 55 °C and 5000 meters above sea level. The motor portrays decreased output data when the ambient operating conditions are exceeded.

What is the coating on the MAC servomotor?

The MAC servomotor comes with a black prime coat painted on its housing. The thickness of this paint can be increased by a maximum thickness of 40μm. This coat is resistant to diluted acids and lyes, chalky build-ups, weathering and yellowing.

At Wake Industrial, we have a huge inventory of these legacy MAC servomotors. This means that you can always turn to us if you need a motor replacement. Moreover, our expertise in handling Indramat products helps us to offer our repair services for your motors in minimum time if that is possible so that you do not encounter any losses in your factory. We can also supply you with a user manual for your motor if you have misplaced your copy.
