Product Description:

The MSK071E-0450-NN-M2-UP1-RNNN is an IndraDyn S synchronous servomotor developed by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It serves as a compact rotary actuator that converts the controlled power delivered by an IndraDrive inverter into precise torque and velocity for industrial automation axes. Typical duties include indexing tables, packaging machinery, and gantry positioning, where closed-loop accuracy, quick response, and an integrated brake reduce external mechanics and simplify system architecture. Its synchronous design supports repeatable starts, stops, and speed changes in tightly controlled motion tasks.

Its enclosure carries a protection rating of IP65, blocking dust ingress and withstanding directed water jets during washdown cleaning. Heat is shed through natural convection, so the motor can be fastened directly to a machine frame without auxiliary blowers. The stator uses winding code 0450, and the E-length housing balances torque output with footprint. Rotor machining to increased concentricity limits radial runout, which helps when the driven load must maintain precise alignment. An electrically released holding brake supplies 23 Nm of static torque to hold vertical axes when power is removed. Position feedback is transmitted over EnDat2.1; the optical sensor resolves 2048 signal periods per revolution, and the rotatable 240° connector helps route the cable clear of moving parts.

The drive is specified for ambient conditions between 0–40 °C, allowing installation in standard factory environments without derating. Torque is delivered through a shaft with keyway, enabling straightforward coupling to pulleys or gearboxes. Coil insulation built to class 155 tolerates high copper temperatures, supporting continuous current that arises in dynamic duty cycles. The electromagnetic core follows size 071 conventions, giving moderate inertia that pairs well with high-resolution feedback while preserving acceleration capability. This layout supports servo axes that alternate between rapid travel and accurate stopping positions.
