Product Description:

The MSK070E-0450-NN-M2-UP0-RNNN servomotor is produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. As an AC permanent-magnet motor, it supplies closed-loop torque and speed control to packaging stations, gantry axes, and other automation equipment. In these roles, the motor forms the electromechanical interface between a Rexroth drive controller and the mechanical load, converting commanded current into rotary motion with high positional fidelity. Its compact E-length housing helps the motor fit into restricted spaces where torque density matters. It is suited to indexing, conveying, and synchronized motion tasks that depend on stable servo response.

Thermal dissipation relies on natural convection, so airflow around the housing must remain unobstructed. The encoder connector is rotatable through 240°, allowing cable exits to be aligned with panel or cable-track orientations. Position feedback travels over EnDat2.1, a synchronous serial interface that carries position, diagnostics, and electronic nameplate data directly to the drive. Inside the encoder, an optical scanning head reads a glass scale that delivers 2048 signal periods, providing high cyclic resolution after interpolation by the drive. This feedback arrangement supports accurate speed regulation and repeatable positioning across changing load conditions.

The encoder keeps count of multiple revolutions through its multiturn absolute design, maintaining position after power loss without homing. A shaft with a keyway simplifies positive-lock transmission of torque to pulleys or couplings. Rotor and stator are ground to increased concentricity tolerances, reducing runout when the motor frame is centered on the machine. The frame size 070 matches standard Rexroth flange and pilot dimensions. Because the motor is supplied without a holding brake, applications that need static load support must use external clamping or energized torque.
