Product Description:

The MSK071E-0300-NN-M1-UP0-NNNN is an IndraDyn S synchronous servomotor manufactured by Bosch Rexroth Indramat as part of the MSK IndraDyn S Synchronous Motors series. Within industrial automation systems, it converts regulated current from a drive controller into tightly controlled shaft rotation, delivering coordinated position, speed, and torque for robotic joints, packaging stations, and general motion axes. Its synchronous design supports responsive acceleration and stable low-speed operation in applications that require repeatable movement over frequent start-stop cycles. This makes the motor suitable for machines that depend on accurate axis coordination without adding unnecessary installation complexity.

The motor housing follows the standard design and releases heat to the surrounding air through natural convection, eliminating the need for forced fans or liquid circuits. Its feedback connector can be oriented through a rotatable range of 240°, simplifying cable routing in cramped cabinets. Encoder data are exchanged over the Hiperface interface, allowing analog sinusoidal and digital parameter channels to share one cable pair with the drive. Inside the encoder, an optical disc generates 128 signal periods per mechanical revolution, which supports smooth velocity control and accurate commutation. The sensing principle is optical, so position information is not affected by magnetic stray fields near high-current busbars. This arrangement also helps keep wiring orderly where connector access is limited by nearby machine hardware.

Long-range position tracking is provided by a multiturn absolute encoder, which counts multiple shaft revolutions without external batteries. Torsional power is delivered through a shaft with keyway, enabling secure coupling to pulleys or gearboxes. That layout supports positive torque transfer when the motor is connected to components that must resist slip under changing loads. The motor size is 071, and the housing uses length code E to keep the installation envelope compact. Electrical characteristics align with winding code 0300, allowing the drive to apply current limits matched to this coil set. The unit is supplied without a holding brake, so the load must be held by the drive or by external mechanics when power is removed.
