Product Description:
The MSK070C-0300-NN-M3-UG1-NNNN is an IndraDyn S synchronous servomotor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. The unit converts drive current into accurate rotary motion for positioning axes, feeders, and other tasks that require closed-loop speed and torque control in industrial automation lines. Its plain shaft couples directly to gearboxes or driven elements, and the integral encoder supplies real-time feedback to the connected drive controller. This arrangement supports repeatable acceleration, deceleration, and holding behavior during frequent motion cycles. It is well suited to packaging, handling, and transfer systems where motion quality must remain consistent across repeated cycles.
Its thermal management relies on natural convection, so the mounting location must allow unrestricted airflow rather than forced-air or liquid cooling. A cast housing sealed to IP65 helps keep dust and water jets away from the internal windings, which can make cabinet installation unnecessary in suitable machine areas. The motor operates in ambient temperatures from 0 to 40 °C without output derating, and the insulation system meets class 155 limits for winding temperature. Frame code 070 indicates a 70 mm mounting flange, while length code C and winding code 0300 determine the motor's active stack and torque-speed behavior. Passive cooling also avoids external fan assemblies and coolant plumbing at the motor.
Position feedback is transmitted through a Hiperface interface that works with drive controllers supporting synchronous serial communication. The feedback device uses a capacitive sensor with 16 signal periods and multi-turn absolute position tracking, so homing after power loss is not required. The encoder connector can be rotated 240° to simplify cable routing in compact machine frames, which is useful when the motor is mounted close to guards, gearboxes, or adjacent axes. An electrically released holding brake provides 23 Nm of static torque, which keeps vertical axes secured when the drive is de-energized.
