Product Description:
The MSK040C-0450-NN-M2-UP0-NNNN is an IndraDyn S synchronous servomotor built by Bosch Rexroth Indramat for closed-loop motion tasks in the MSK IndraDyn S Synchronous Motors series. With a 040 frame size and C length, this motor fits compact axes that require precise torque and position control in pick-and-place modules, feeders, and handling gantries across automated production cells. Its compact format also suits installations where mounting space is limited but repeatable servo response is still required. When paired with a suitable controller, it supports controlled acceleration, stable speed regulation, and accurate stopping at target positions.
This model relies on natural convection to move heat from the stator surface to ambient air, eliminating the need for forced ventilation hardware. Feedback is generated by an optical encoder that communicates through the EnDat 2.1 interface, which sends absolute position data and diagnostic information directly to the drive. The encoder produces 2048 signal periods per revolution, and the internal counting electronics use a multi-turn absolute design so the axis can retain position information after power cycling. Mechanical installation is simplified because the feedback connector is rotatable through 240°, allowing cable routing to match cabinet or drag-chain layouts without twisting the cable.
The motor is supplied without a holding brake, so applications that need power-off shaft locking must use an external clamp or rely on drive torque. This arrangement is common on axes that use external braking or do not require load holding at standstill. A housing protection rating of IP65 helps keep dust and water jets away from internal windings when the shaft seal remains intact. Power is transmitted through a shaft with keyway, giving positive mechanical engagement to couplings or pulleys. Class 155 insulation allows the windings to operate at elevated temperatures before thermal limits are reached, which supports use in typical industrial ambient conditions. The winding code is matched to the electrical characteristics expected by compatible drive systems.
