Product Description:
The MSK071C-0300-NN-S3-UG1-NNNN is an IndraDyn S synchronous servo motor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. In automated equipment, it provides precise torque and position control for axes that require accurate feedback, including pick-and-place gantries and tooling drives. Its compact housing supports direct-coupled installation, which helps reduce backlash from extra transmission components and keeps motion response consistent during short, repeated moves. The integrated feedback system also allows the drive to track rotor position closely during acceleration, deceleration, and holding tasks. It is also suited to applications that require smooth low-speed control together with repeatable end-position accuracy.
The motor uses natural convection for cooling, so air must circulate around the housing without relying on external blowers. The enclosure is rated IP65, which helps keep dust and low-pressure water jets away from internal motor parts and the plain shaft area. An electrically released holding brake is mounted on the rear flange, and it provides 23 Nm of static torque when the axis must remain in place after drive power is removed. Position information is transmitted through a Hiperface interface, giving the drive a reliable channel for feedback data. The motor uses frame code 071, which places it in a compact size range suited to tightly spaced machine layouts. This combination of passive cooling and sealed housing works well on machines where open ventilation is limited.
Inside the stator, Class 155 insulation supports elevated winding temperatures during normal operation. The single-turn capacitive encoder delivers 16 signal periods per mechanical revolution, and its connector can rotate through 240° to improve cable routing where enclosure space is limited. Rated torque and speed are available across an ambient range of 0 to 40 °C when convection paths remain unobstructed. The winding code 0300 matches the electrical characteristics expected by compatible IndraDrive amplifiers. The C-length housing keeps the overall depth compact, which helps when mounting space behind the machine plate is restricted. The adjustable connector position also helps avoid tight cable bends near nearby structural parts.
