Product Description:

The MSK071C-0450-NN-M1-AG1-NNAN is a synchronous servo motor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. As an IndraDyn S servo motor, it converts drive commands from a controller into precise rotary motion for positioning or speed-regulated tasks on automated machinery. Its C-length 071-frame housing uses a reduced runout design and integrates a sealed stator and rotor assembly. This arrangement supports closed-loop control and helps maintain smooth motion on axes that require repeatable positioning.

The enclosure carries a protection rating of IP65, so internal components remain isolated from dust ingress and low-pressure water streams commonly present in production cells. Heat is dissipated to ambient air through natural convection, eliminating the need for forced cooling hardware. Position feedback is delivered through a Hiperface encoder, which combines power and data over a single hybrid cable and simplifies installation. Within that feedback unit, an optical reader tracks 128 signal periods to support smooth velocity regulation. A plain shaft end allows direct coupling to pulleys, clutches, or precision gearboxes without keyways or splines, which helps minimize concentricity error and vibration. The feedback arrangement also supports accurate speed and position monitoring during dynamic motion.

An electrically released holding brake supplies 23 Nm of static torque, maintaining axis position when power is removed. The feedback device stores absolute position across revolutions with a multi-turn absolute mechanism, so the controller can read the true rotor angle immediately after startup. This helps the axis return to operation without a separate homing step. Class 155 insulation permits continuous winding temperatures aligned with F-class limits for reliable duty cycles in packaging or assembly equipment. The motor operates in ambient conditions from 0 to 40 °C, matching standard cabinet environments. Its A-side power connector points the supply leads toward the drive cabinet for shorter cable routing, and the 0450 winding code identifies the electrical values used by IndraDrive amplifiers for current limits and commutation tables.
