Product Description:
The MSK070C-0300-NN-S1-UP1-NNNN is an IndraDyn S synchronous servo motor manufactured by Bosch Rexroth Indramat and supplied within the MSK IndraDyn S Synchronous Motors series. Designed for precision motion control, this motor is used in automated machinery where fast response, accurate positioning, and high repeatability are required. It converts drive current from an IndraDrive amplifier into controlled torque and speed for coordinated multi-axis operation in assembly stations, handling systems, and packaging equipment. The motor works well on axes that require smooth acceleration, controlled deceleration, and repeatable movement during continuous production cycles. That control behavior is useful in pick-and-place units, feeders, and synchronized transfer systems.
The motor uses natural convection to remove heat from the stator housing, so no external blower is required. It has a standard mechanical design, and size 070 with length code C gives the unit a compact footprint for medium-power axes. Winding code 0300 matches the electrical characteristics used with common 400 V IndraDrive inverters. A factory-mounted, electrically released brake provides 23 Nm of holding torque for axes that must remain in place when power is removed. Feedback is transmitted through a Hiperface interface, and the sensor produces 128 signal periods per mechanical revolution for commutation and position control.
Inside the feedback assembly, an optical scanning head detects incremental lines with consistent signal quality. The system uses single-turn position tracking, so the absolute position is referenced within one shaft revolution instead of across multiple turns. The encoder plug is rotatable through 240°, which helps route the cable to suit the machine layout and reduces strain at the connector. Mechanical output is delivered through a shaft with a keyway, providing a positive drive connection for couplings, pulleys, or similar transmission elements. This shaft style helps limit slip when the axis is exposed to changing loads or frequent reversing motion.
