Product Description:
The MSK071C-0300-NN-M3-UP1-NNNN servomotor is produced by Bosch Rexroth Indramat and is part of the MSK IndraDyn S Synchronous Motors series. It serves as a rotary actuator for precise positioning and speed regulation in automated production equipment. The motor uses frame size 071 and length code C to match medium-torque applications, and its standard mechanical design supports direct mounting on packaging lines, gantries, and converting systems without external enclosures. Its synchronous design also supports responsive speed changes and repeatable motion control when it is paired with a compatible servo drive.
Heat dissipation is handled through natural convection, so adequate clearance around the housing must be maintained rather than relying on forced air. A protection category of IP65 keeps dust and low-pressure water jets away from internal parts, enabling installation on the machine frame. Position feedback is delivered through a Hiperface interface; inside the feedback unit, a resolution of 16 signal periods per mechanical turn is produced by a capacitive sensing element. This arrangement supplies the controller with absolute position values at power-up and fine incremental data during motion, supporting tight velocity loops and smooth torque modulation on high-cycle axes. The sealed housing and integrated feedback help the motor fit exposed mounting locations without requiring separate external sensing hardware.
The multiturn absolute encoder retains its count during power loss, and its connector can be rotated through 240°, simplifying cable exit in restricted cabinets. Motion is secured at standstill by an electrically released brake that provides 23 Nm of holding torque, making the motor suitable for vertical or suspended loads. Mechanical power passes through a shaft with keyway, allowing positive coupling to pulleys or gears. Class 155 insulation supports elevated winding temperatures associated with cyclical duty. The standard build, winding code 0300, frame 071 stator, and an ambient temperature range of 0–40 °C suit drive ratings and plant conditions found in general automation. The brake supports load holding at standstill, and the keyed shaft allows direct coupling to common transmission elements.
