Product Description:

The MSK070D-0300-NN-S3-UP0-NNNN is a synchronous servo motor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It converts three-phase electrical power into controlled torque for precise axis positioning in packaging, printing, and handling equipment. Its synchronous design supports repeatable motion on axes that require accurate starting, stopping, and speed control during automated cycles. The compact platform also integrates directly with compatible Rexroth drive controllers for coordinated motion in production systems.

The unit dissipates heat through natural convection, so the housing fins must remain clear for unrestricted airflow. Its enclosure has an IP65 rating, which helps protect the internal windings from dust and low-pressure water spray on factory floors. Position feedback is transmitted through Hiperface, and the capacitive single-turn encoder provides 16 signal periods per revolution for commutation. That feedback arrangement allows the drive to monitor rotor position continuously during startup, speed changes, and commanded stops. The feedback connector can be rotated through 240°, which helps route the cable in confined installations without placing unnecessary twist on the harness.

The motor uses frame code 070, and length code D gives it a longer active stack for higher continuous torque within the same cross-section. Insulation class 155 supports elevated winding temperatures during transient peaks, and winding code 0300 matches the motor to compatible drive settings. The shaft has a keyway for positive mechanical coupling, and the standard design does not add special coatings or extra seals beyond the basic enclosure protection. Ambient operation is limited to 0 °C to 40 °C, so the motor should be installed where surrounding temperatures stay within that range. The motor is supplied without a holding brake, so any static load must be held by the drive or by external mechanics.
