MSK IndraDyn S Synchronous Motors
Rated 4.4 stars (8 total reviews)
The MSK071E-0300-NN-S2-UG1-RNNN is a synchronous servomotor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It converts controlled electrical power from a drive controller into accurate rotary motion for automation axes such as carton formers, pick-and-place gantries, and small machining spindles. With integrated feedback and an internal brake, the motor serves as a compact actuator where closed-loop speed, torque, and position control are required on the factory floor.
Thermal management is handled by natural convection; the housing fins release heat directly to surrounding air so cabinet airflow planning remains simple. Rotor position is delivered to the drive through the bi-directional EnDat2.1 protocol, supporting high-resolution feedback at system power-up without incremental homing. Inside the encoder, an optical disk yields 2048 signal periods, establishing a fine electrical angle for tight velocity loops. Because the encoder is of the singleturn type, it reports absolute position within one revolution, which is adequate for gear-coupled shafts that never exceed 360° of commanded travel. For holding a load at rest, an electrically-released brake supplies 23 Nm of static torque so vertical axes stay fixed when power is removed.
The mechanical interface favors direct coupling; a plain shaft lets designers press-fit flexible couplings without keyways. Cable routing is simplified by the encoder plug that is rotatable, 240°, allowing strain-relief regardless of cabinet orientation. Dynamic characteristics are defined by winding code 0300, which specifies the motor’s voltage constant and current limits for use with Rexroth HCS drives. Finally, the stator and rotor are manufactured to an increased concentricity standard, reducing radial run-out and supporting smoother motion at high speeds without additional mechanical alignment steps.
