Product Description:

The MSK070D-0300-NN-M2-UG1-RNNN is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It serves as a precision drive element in industrial automation, converting controlled electrical energy into accurate rotary motion for positioning tables, feeders, and gantry axes. The D-length housing and 070 frame size permit compact installation, and the unit integrates directly with IndraDrive controllers that require tight velocity and torque regulation for repeatable movement. This arrangement suits coordinated motion tasks where responsive acceleration and consistent stopping accuracy are required.

Heat is removed through natural convection, so the stator housing dissipates losses without external fans or liquid circuits. Position feedback is generated by an optical encoder that communicates over the EnDat2.1 interface, and this digital link transfers absolute position and diagnostic data on a single cable. The encoder offers 2048 signal periods per revolution, allowing fine interpolation inside the drive. Because it is a multiturn absolute device, rotor angle information across 4096 turns is retained after power loss, eliminating homing cycles. A spring-applied, electrically released brake delivers 23 Nm of static torque to secure vertical or indexing loads whenever the controller is disabled. This feedback arrangement helps the connected drive maintain accurate commutation and stable closed-loop control during changing load conditions.

The motor carries an IP65 protection rating that blocks dust ingress and low-pressure water jets on open machine frames. Reliable duty is permitted for ambient temperatures between 0–40 °C, matching most production floors without derating. A plain shaft minimizes backlash when clamped to zero-play couplings, and the increased concentricity design keeps radial runout low for smooth rotation. The rotatable 240° encoder connector eases cable routing, and winding code 0300 indicates the electrical constants suited to IndraDrive inverters. Insulation built to thermal class 155 permits continuous current flow while keeping winding temperatures within safe limits for long service life. The connector position also helps routing where installation space around the motor is limited.
