Product Description:
The MSK030C-0900-NN-M3-UP0-NNNN is a servo motor from the MSK IndraDyn S Synchronous Motors series manufactured by Bosch Rexroth Indramat. As a compact IndraDyn S synchronous servomotor, it converts the pulse-width-modulated output of Rexroth inverters into precise rotary motion for tasks such as indexing tables, feeder drives, and small handling axes. The motor’s combination of permanent-magnet excitation and digital feedback allows tight position loops and repeatable torque generation, making it suitable for high-accuracy industrial automation cells.
Thermal management relies on natural convection, so heat dissipates into the surrounding air without fans or external cooling equipment. The housing carries an IP65 rating, meaning it is dust-tight and can withstand low-pressure water jets, which allows installation on open machine frames. For feedback, the motor integrates a Hiperface interface that transmits digital position data and commutation information to the drive in a single hybrid cable. The measuring element delivers 16 signal periods per mechanical revolution, and after internal interpolation the controller obtains high-resolution angle data for smooth velocity regulation. Signal generation uses a capacitive principle, eliminating optical disks and maintaining accuracy in environments where oil mist or condensation might obscure light-based sensors.
The feedback module is a multi-turn absolute design, so it counts full revolutions as well as the current angular position and preserves this data after power loss for immediate drive homing. Mechanical holding force is not provided because the unit ships without a holding brake, so applications that need static load support must secure the load through the drive or an external brake. Acceptable ambient conditions span 0–40 °C, matching typical control cabinet climates without derating. Power transmission occurs through a shaft with a keyway, giving a positive drive to pulleys or couplings and simplifying shaft-to-hub alignment during assembly.
