Product Description:

The MSK103A-0302-NN-M2-UG0-NNNN is an IndraDyn S synchronous servomotor manufactured by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It is intended for precision positioning and cyclic-duty operation, where the motor couples directly to a servo inverter so machine axes can follow commanded speed or torque profiles with very little backlash from the drivetrain. This arrangement suits handling modules, packaging equipment, and metal-cutting machines that require coordinated multi-axis motion. Its compact mechanical format also helps when axis spacing is limited and accurate feedback is needed for repeatable motion control.

Thermal exchange relies on natural convection, so the motor does not require external blowers or liquid cooling circuits. The feedback plug is rotatable through 240°, which helps align cable routing with the machine layout. Position data are transmitted through the EnDat 2.1 digital interface, and the optical encoder provides 2,048 signal periods per revolution to the drive controller. The housing has an IP65 rating, which helps protect internal components from dust and low-pressure water jets during washdown or coolant splash. Because the motor is supplied without a holding brake, any static load must be held by the drive or by external mechanical means.

Persistent position tracking is supported by the encoder’s multiturn absolute capability, allowing the shaft position to be retained across power cycles for homing-free restart behavior. Continuous operation is permitted in an ambient range of 0 to 40 °C. The output uses a plain shaft, which supports precision couplings without key-related runout. Insulation class 155 allows the winding system to tolerate the heat that can develop during demanding duty cycles. These characteristics make the motor suitable for repeatable servo applications that need accurate position feedback, stable thermal behavior, and a simple shaft interface.
