Product Description:

The MSK071E-0300-NN-S2-UP2-RNNN is an IndraDyn S synchronous servomotor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. Designed for closed-loop motion axes, the unit converts electrical energy into controlled rotary motion for positioning tables, pick-and-place modules, and similar automation tasks. By combining precise feedback with a secure output arrangement, it supports repeatable torque and speed regulation for machine tools, packaging equipment, and other automated systems that require accurate response during frequent starts, stops, and direction changes. Its synchronous design allows the drive to maintain accurate rotor position in applications that demand coordinated motion between several axes. This makes it suitable for equipment where repeatability matters more than simple constant-speed rotation.

Thermal dissipation is achieved through natural convection, so the motor relies on surrounding air movement rather than an integrated fan. This cooling method keeps the layout simple and avoids the added maintenance associated with forced-air hardware. The stator and rotor are ground for increased concentricity, which helps keep runout low during high-speed cycles and supports smooth mechanical operation. Feedback is supplied by an EnDat 2.1 optical encoder configured as a single-turn device that produces 2048 signal periods per mechanical revolution, allowing the drive controller to interpolate fine position data. An electrically released holding brake provides 30 Nm of static torque to hold vertical or load-bearing axes when power is removed.

Mechanical attachment uses a shaft with a keyway, which supports secure torque transfer to pulleys, couplings, or similar driven elements. This shaft style is commonly used where positive mechanical engagement is preferred over friction-only clamping. Dimensional coding identifies the motor as motor size 071 with a housing length of motor length E, giving a compact form factor for installation in multi-axis assemblies where space is limited. Electrical behavior corresponds to winding code 0300, which matches the motor to compatible IndraDrive servo amplifiers. A rotatable 240° encoder connector helps route the feedback cable in tight cabinets while reducing twisting at the plug and helping protect the seal during installation.
