Product Description:
The MSK070D-0300-NN-M1-AG1-NNAN is an IndraDyn S synchronous servo motor produced by Bosch Rexroth Indramat in the MSK IndraDyn S Synchronous Motors series. As a permanent-magnet AC unit, it provides precise torque and speed control for positioning axes, pick-and-place gantries, and other automated motion platforms. When paired with a compatible drive, it converts commanded electrical input into controlled rotary motion for repeatable starts, stops, and speed changes. The model includes an electrically released holding brake so mechanical loads can remain locked when power is removed and axis drift can be limited during planned stops.
Thermal management relies on natural convection, so heat dissipates through the housing without auxiliary fans or liquid circuits and surrounding airflow should remain unobstructed. Because no external blower is required, the installation does not need separate fan hardware or coolant plumbing around the motor body. The housing is sealed to IP65, which helps block dust and water jets in machine-mounted installations. The electrically released brake provides 23 Nm of static torque for load holding on suitable vertical or inclined axes. Feedback uses optical scanning and delivers 128 signal periods per revolution for smooth speed regulation and accurate position interpolation.
Position data is transmitted through the Hiperface interface, and the feedback system uses multi-turn absolute position storage so the axis can retain position information through power cycles. This arrangement helps the drive recover position information after restart without requiring a homing move in many machine layouts. The motor has size 070 with length code D, and a plain shaft with reduced runout helps limit coupling misalignment in compact assemblies. Winding code 0300 sets the coil characteristics for this configuration, while the A-side power connector supports straightforward cable routing along linear guides. Continuous operation is permitted from 0 to 40 °C, and the winding insulation uses class 155 for standard industrial ambient conditions.
