Product Description:

The MSK070C-0300-NN-M2-UP0-RNNN is a rotary actuator manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It operates as a closed-loop servomotor that converts electrical drive output into precise mechanical rotation for positioning axes, pick-and-place heads, and automated packaging spindles. By combining its electromagnetic section with optical feedback, the motor provides both torque and high-resolution position data to the controller. This supports repeatable motion in packaging, handling, and indexing equipment where speed changes and stop positions must remain consistent from cycle to cycle. It is intended for servo systems that require accurate response under changing loads.

Heat produced by the stator windings is removed through natural convection, so the housing can dissipate thermal energy without an external fan. The motor has an IP65 rating, which keeps dust out and resists low-pressure water jets in typical factory settings. The encoder generates 2048 signal periods per revolution, and the data is transmitted over the EnDat2.1 serial interface for digital position feedback. Because the feedback device is multi-turn absolute, the drive can retain shaft angle and revolution information through power cycles instead of requiring a homing move before operation resumes. Digital encoder communication also supports stable feedback transfer when the motor is connected to a compatible servo drive.

The encoder plug can be rotated through 240°, which allows flexible cable routing where space around the motor is limited. Continuous duty is permitted in an ambient range of 0–40 °C, making the unit suitable for enclosed machine areas that do not rely on forced room cooling. Class 155 insulation supports elevated winding temperatures during long operating periods. Winding code 0300 identifies the electrical characteristics used for this motor. The output shaft uses a keyway for torque transmission, the C length balances inertia and torque density, and the motor is supplied without a holding brake, so position holding at standstill must come from drive torque or external mechanics. Greater concentricity also helps reduce runout in applications that require smooth rotary motion.
