Product Description:

The MSK040C-0450-NN-S1-UP0-NSNN is a synchronous servo motor manufactured by Bosch Rexroth Indramat and part of the MSK IndraDyn S Synchronous Motors series. This motor is intended for servo axes that demand precise, repeatable motion while maintaining a small footprint in compact machine assemblies. By pairing winding code 0450 with an internal permanent-magnet rotor, the unit delivers dynamic torque for packaging, assembly, and electronics production equipment. Its compact construction also suits indexing tables, feeders, and transfer axes where responsive motion and accurate positioning are required.

The housing relies on natural convection to remove heat, so no external blower or liquid circuit is required. A sealed construction rated at IP65 keeps dust and water jets away from the internal laminations and encoder. Continuous operation is permitted at ambient temperatures from 0 to 40 °C, which suits typical factory conditions. Feedback cable routing is simplified by a rotatable 240° encoder connector that can be positioned after mounting to reduce cable strain. Position data is transferred through the Hiperface interface, allowing the drive to read absolute rotor position immediately after power-up. Optical single-turn scanning keeps interpolation error low, while the C length and 040 frame size fit tight mechanical spaces and still provide room for the required winding volume.

The feedback system resolves each electrical revolution into 128 signal periods, which provides enough granularity for smooth speed control at low velocities. Because the motor is supplied without a holding brake, external holding devices are needed when vertical loads must remain fixed during a power loss. Torque is transmitted through a shaft with a keyway, which helps prevent slip under reversing load conditions and supports secure coupling to driven components. Insulation class 155 supports elevated winding temperatures during operation, helping the motor withstand repeated duty cycles in demanding automation service.
