Product Description:

The MSK071D-0200-NN-M2-UP0-RNNN is an IndraDyn S synchronous servo motor developed by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. In motion-control systems, it converts drive current into precise rotary motion for indexing tables, gantry axes, and forming machines. Tight electrical commutation and low rotor inertia help the motor follow dynamic command profiles while maintaining repeatable positioning accuracy. This operating behavior makes it suitable for applications that need responsive acceleration and stable closed-loop motion.

Thermal management relies on natural convection, so no additional fans or liquid circuits are required. The housing carries an IP65 rating, which helps protect internal components from dust and low-pressure water jets in typical factory areas. Continuous operation is permitted in ambient air from 0–40 °C, supporting full output in common indoor industrial conditions. Servo feedback is transferred through an EnDat2.1 digital interface with a rotatable 240° plug that helps with cable routing in confined spaces. The optical encoder provides 2048 signal periods per revolution, and the multiturn function gives the controller absolute shaft position over multiple revolutions for accurate feedback processing.

Mechanical power is transmitted through a shaft with keyway, allowing the motor to work with standard keyed hubs and couplings. The motor uses winding code 0200 and a size 071 frame, while the D length extends the active core for higher continuous output in this housing size. Thermal endurance is supported by insulation class 155, which permits winding temperatures up to 155 °C during extended duty. The unit is supplied without a holding brake, so any stationary load must be secured by drive torque or an external locking device. This arrangement is often preferred where brake hardware is unnecessary and reduced mechanical complexity is desirable.
