Product Description:

The MSK040B-0600-NN-S2-UP1-NNNN is an IndraDyn S synchronous servomotor manufactured by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It converts controlled electrical energy into precise rotary motion for positioning axes, pick-and-place heads, and other closed-loop devices used throughout industrial automation cells. The motor is intended for applications that need accurate speed control, repeatable positioning, and dependable response during continuous machine movement.

Heat generated during operation is dissipated by natural convection, so no auxiliary fans are required inside the machine cabinet. The motor has frame size 040 and length code B, giving a compact footprint for multi-axis assemblies. Winding code 0600 identifies the electrical characteristics expected by the drive. A shaft with keyway provides positive mechanical coupling, and the housing carries a protection rating of IP65, allowing installation in dusty or splash-prone areas. The electrically released holding brake supplies 4 Nm of static torque to secure loads when power is removed. Position data are resolved into 2048 signal periods and transmitted to the controller through the bidirectional EnDat2.1 interface, giving high-resolution absolute feedback with minimal wiring.

The feedback connector can be rotated through 240°, which helps route cables cleanly in tight enclosures. Because the encoder is the Singleturn type, it reports the absolute shaft angle within one revolution, while multi-turn counting is handled by the drive if needed. Optical sensing technology supports stable signal transmission even under vibration. The motor uses insulation class 155, which allows elevated winding temperatures without degrading the varnish system. Consistent performance is specified for ambient conditions between 0-40°C, allowing the motor to operate near other heat-producing equipment without dedicated climate control.
