Product Description:

The MSK040B-0450-NN-S1-UP0-NNNN is a synchronous servomotor built by Bosch Rexroth Indramat and assigned to the MSK IndraDyn S Synchronous Motors series. As a torque-controlled rotary actuator, it interfaces with IndraDrive controllers to move machine axes, conveyors, and gantries with high positional accuracy. The unit’s electromagnetic design allows closed-loop speed regulation so fabrication cells, packaging platforms, and assembly stations can coordinate motion sequences in real time. This operating profile suits applications that need repeatable starts, stops, and short positioning moves throughout continuous machine cycles. Because servo feedback is processed continuously by the drive, the motor can correct speed deviations quickly when load conditions change during indexing or transfer tasks.

Its thermal management relies on natural convection, meaning heat dissipates through the housing surface without auxiliary fans or liquid channels. The motor retains the standard construction code, so mounting dimensions match other units in the series. Feedback data are delivered through a Hiperface interface that combines absolute position and incremental signals for the connected drive. Inside the encoder, an optical scanning system reads a glass scale with 128 signal periods, providing fine angular resolution for velocity control. The feedback plug is rotatable through 240°, which helps route the cable around nearby machine members without forcing a fixed exit direction. This arrangement keeps the motor body simple and quiet while avoiding the extra wiring associated with forced-air accessories.

The encoder is single-turn, so absolute position is retained only within one mechanical revolution, which suits rotary tables and pick-and-place heads that reference at startup. Mechanical power is transmitted through a shaft with a keyway, simplifying coupling to pulleys or gearboxes. Electromagnetic behavior matches winding code 0450, balancing current demand and torque output for medium-inertia loads during normal servo operation. The motor uses size 040 with length code B, giving a compact housing for narrow machine spaces. That combination is useful where the machine must package output torque in a small installation envelope. The assembly is supplied without a holding brake, so static load retention must be provided externally when the axis is stopped.
