Product Description:

The MSK040B-0600-NN-M2-UP0-NNNN is an IndraDyn S synchronous servomotor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. As a tightly coupled drive component, it converts sinusoidal current from a Rexroth servo amplifier into precisely regulated rotary motion. The motor integrates an absolute optical encoder so the drive controller can close the position loop without external transducers. This arrangement supports accurate tool positioning, coordinated gantry travel, and other automation tasks that depend on repeatable speed and torque performance while keeping the feedback system inside the motor housing.

This B-length, size 040 unit relies on natural convection for heat dissipation, allowing installation where continuous load stays within the rated thermal range. The die-cast housing has an IP65 protection rating that blocks dust ingress and resists water jets from any direction. Motor feedback exits through a rotatable 240° connector and uses the EnDat2.1 serial interface, which reduces cable strain during routing in confined machine spaces. Inside the measuring system, an optical scanner resolves 2048 signal periods per mechanical turn, and the integrated multi-turn absolute encoder stores revolution data in nonvolatile memory so the controller retains position information after a power cycle.

The motor is intended for continuous operation in ambient temperatures from 0 to 40 °C. Torque is transmitted through a shaft with a keyway, which allows secure coupling to pulleys, pinions, or gear inputs. The windings use insulation class 155 for thermal endurance, and winding code 0600 identifies the electrical data matched to compatible Rexroth amplifiers. Because the motor is supplied without a holding brake, the axis must be secured by external clamping or drive-generated holding torque when power is removed.
