Product Description:

The MSK071E-0450-NN-M2-UG1-RNNN is a three-phase servomotor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. As an IndraDyn S synchronous servomotor, it delivers closed-loop torque and position control for industrial automation axes such as packaging heads or gantry drives. This operating role allows the motor to support accurate speed regulation and repeatable positioning during continuous machine motion.

Thermal behavior is managed by natural convection, so heat is released through the housing without external fans. The frame carries an IP65 rating that seals internal components from dust and low-pressure water jets, allowing cabinet-free mounting near the machine. Reliable operation is specified between 0–40 °C; outside that range, derating or supplemental cooling is required. The motor has size 071, length code E, and winding code 0450. This winding corresponds to the electrical resistance and inductance values expected by a compatible IndraDrive amplifier, helping current loops remain stable during dynamic cycles. Increased concentricity machining reduces shaft runout so couplings remain aligned at high speeds, and the plain shaft supports direct clamp coupling.

The optical encoder uses an EnDat2.1 serial interface and provides 2048 signal periods per revolution. Because it is a Multiturn Absolute encoder, position remains valid through 4096 mechanical turns even after power loss, which removes the need for a homing routine at startup. The encoder connector can be rotated 240 degrees, making cable routing easier in tight cable tracks. An electrically released brake supplies 23 Nm of static torque, allowing vertical loads to remain fixed whenever the drive is disabled. Class 155 insulation tolerates the additional heat from the brake, and the increased concentricity design helps keep the brake air gap uniform for consistent torque.
