Product Description:
The MSK103D-0300-NN-S2-UG0-RNNN is an IndraDyn S synchronous servomotor manufactured by Bosch Rexroth Indramat. It belongs to the MSK IndraDyn S Synchronous Motors series and serves as a rotary drive element in industrial automation where precise torque and position control are required. Its design emphasizes increased concentricity, supporting smooth rotation at application speeds.
Heat is removed through natural convection, eliminating external blowers and allowing installation in sealed cabinets. The housing carries an IP65 protection rating, so dust ingress and water jets do not interfere with operation. Its encoder connector is rotatable through 240°, simplifying cable routing and preserving the integrity of the EnDat2.1 serial interface. The optical measuring system inside the motor delivers 2048 signal periods per revolution; when interpolated by the drive, this fine resolution supports high loop gains. The shaft end uses a plain shaft, facilitating rigid couplings and pulleys. The motor is supplied without a holding brake, so mechanical locking or drive torque must maintain position when power is removed.
The motor occupies the 103 frame size with the elongated D length variant, giving a favorable torque-to-inertia ratio for medium-power axes. Its stator winding with code 0300 aligns electrical parameters with drive modules for consistent current utilization. Thermal endurance is secured by an insulation class of 155, permitting winding temperatures well above ambient without degrading varnish life. Inside the encoder, a single-turn track reports absolute position within one revolution, which is sufficient for applications where homing establishes a multi-turn reference. Continuous service is specified for ambient conditions from 0 to 40 °C, so performance remains stable in typical shop-floor environments. Because the connector can be oriented during installation, cables clear adjacent modules even when space is limited.
