Indramat MDD Series Motors

The MDD style motor is a Synchronous AC servo motor available in nine different rotor diameters.

MDD021, 025, 041, 065, 071, 090, 093, 112, and 115

Major options for the motors in this series include with/without keyway, with/without holding (blocking) brake, and either single or multiturn feedback (it is NOT an encoder). There are several different rotor winding codes in each size range which designate the characteristic speed of the motor. The MDD series motors can be used with the DDS and DKS series servodrives.

Digital feedback Indramat motors cannot be disassembled and reassembled in the field. We provide factory repair with 24 turnaround, and we have chartered aircraft available so you can be back up and running as fast as possible.

The MSK motor series is particularly distinguished by its broad power range and narrow size increments. The high torque density of these synchronous servo motors facilitates a particularly compact design with maximum torques of up to 495 Nm. We supply the motors with encoder systems for standard or precision requirements depending on the required level of accuracy. Both encoder versions are available in both single-turn and multi-turn design. A wide range of additional options, such as keyway, holding brake and increased concentricity, as well as the high protection type IP65 enable use with a fan, water cooling and ATEX. For applications with increased continuous power, retrofit blower units are available for axial or radial mounting. Intrinsically safe blower motors (UL thermally protected F) with protection type IP65 make the single-phase connectable blower units reliable – i.e. no external protection via a circuit-breaker is required. Maximum performance requirements can be met with the available water cooling option.

• A CAUTION!

Do not touch carelessl Risk of injury due to hot surface. Allow to cool A down before servicing. Do not strike the shaft and and do not exceed the parmissible axial and radial forces of the motor
