Product Description:
The MSK071E-0300-NN-M1-UP0-NSNN is a three-phase IndraDyn S synchronous servo motor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. Within automated assembly lines and packaging cells, this motor provides closed-loop torque and position control for linear or rotary axes that demand high accuracy and repeatable motion profiles. Its compact 071 frame and E-length stator stack allow installation in tight machine frames while delivering the continuous power density expected from a permanent-magnet servo drive. When paired with a compatible servo controller, the motor supports responsive acceleration, accurate positioning, and stable speed regulation in common industrial motion applications.
Electrically, the stator is wound to code 0300, which suits moderate current demand. Cooling relies on natural convection, so no fan or liquid lines are required and free air circulation around the housing should remain unobstructed. The housing has an IP65 rating, which helps protect internal components from dust and low-pressure water exposure. Feedback is transmitted through Hiperface, allowing the drive to receive position and device data over a hybrid cable. Encoder resolution reaches 128 signal periods, supporting fine interpolation inside the control loop, and the connector can rotate through 240° to simplify cable routing. Permitted ambient temperature is 0 to 40 °C, and the motor comes without a holding brake for axes that rely on external holding force or drive-controlled torque at standstill.
Mechanical coupling is provided by a shaft with a keyway, giving a positive connection to pulleys or gearboxes. Position retention across multiple revolutions is available because the encoder uses a multi-turn absolute design, so the drive can retain rotational reference after a power cycle. Thermal endurance is supported by the class 155 insulation system, which allows elevated winding temperature while maintaining dependable motor operation. This arrangement fits indexing tables, feed axes, and other machines that require compact servo performance without auxiliary cooling hardware.
