Product Description:

The MSK071C-0450-NN-S1-UP0-NNNN is an IndraDyn S synchronous servomotor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It is used on packaging machines, metal-cutting centers, and general automation lines where precise closed-loop torque and speed control are required. Its synchronous design supports accurate motion on axes that must respond quickly to changing commands and varying load conditions.

This model is cooled by natural convection, so heat is dissipated through the housing without external fans or liquid circuits. A protection rating of IP65 allows installation in areas exposed to dust and low-pressure water jets. Position data travel over the Hiperface interface, and the encoder connector can be rotated through 240° to simplify cable routing. The motor belongs to size 071 with length code C, and its standard design housing supports a rotatable optical feedback head. Winding code 0450 indicates the electrical resistance and inductance values that the drive controller must match. Operation is permitted at ambient temperatures from 0 °C to 40 °C, allowing use in cabinet-mounted systems or on open machine frames.

The optical encoder resolves rotor position into 128 signal periods, providing fine granularity for velocity and commutation loops. That resolution helps the drive maintain smooth low-speed operation and stable response during speed changes. Single-turn feedback, identified as single-turn, returns the absolute shaft angle within one revolution, so short-stroke axes do not need multi-turn tracking. Mechanical power is delivered through a shaft with a keyway, which transmits torque to pulleys or couplings while helping prevent slippage under load. Thermal endurance corresponds to insulation class 155, allowing winding temperatures up to 155 °C before insulation breakdown begins. The unit is shipped without a holding brake, so external clamping or drive torque must secure static positions when power is removed.
