Product Description:

The MSK040B-0450-NN-S1-UP1-NNNN is a synchronous motor manufactured by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It serves as a drive element for industrial automation modules that require precise torque and velocity control under servo regulation, where coordinated motion and repeatable response are important during normal operation. The chosen B length combined with the 040 frame size provides a compact form factor that fits tight axis spacing in multi-motor assemblies while preserving continuous torque capacity.

Thermal dissipation is handled through natural convection, so the housing relies on ambient airflow instead of forced cooling equipment. Position feedback is supplied over the Hiperface serial interface, allowing absolute position data to be exchanged with Rexroth and third-party drives without additional wiring. Inside the feedback assembly, an optical sensing track generates 128 signal periods per mechanical revolution, giving the controller fine angular resolution during interpolation. Electrical connections for the encoder exit through a 240° rotatable connector, permitting cable routing to be aligned with cabinet or machine wall layouts while maintaining strain relief.

The feedback device is a single-turn encoder, meaning absolute position information is retained for one mechanical revolution, while multi-turn counting must be managed by the drive if required. An electrically released holding brake is integrated, and it applies up to 4 Nm of static torque to secure vertical or suspended loads when power is removed. Mechanical power is transmitted through a shaft with a keyway, enabling rigid coupling to pulleys or gear sets. Electromagnetic characteristics are set by winding code 0450, which matches the motor to compatible IndraDrive amplifiers for current and voltage limits. The design uses standard construction for general industrial use.
