Product Description:

The MSK071E-0300-NN-S1-AP1-NNAN is a synchronous servomotor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. As an IndraDyn S servomotor, it converts electrical energy into controlled torque and speed for closed-loop positioning of tooling, gantries, and conveyor axes in automated machinery. The motor integrates a Hiperface encoder and a power connector on the A-side, which helps keep cable routing concentrated at one end of the housing. This layout supports compact machine installations where available mounting space is limited and orderly cable entry is important.

Cooling relies on natural convection, so heat is removed through the motor housing without fans or liquid circuits. Its reduced run-out shaft design helps keep radial error low, which supports accurate motion and reduces stress on connected couplings. Position data is transmitted over a Hiperface interface that combines sine-cosine signals with digital memory for reliable startup reference information. The encoder provides 128 signal periods per mechanical turn, giving the drive a solid basis for interpolation and stable speed control. For load holding, the motor includes an electrically released holding brake that clamps the rotor by spring force when supply voltage is removed.

The holding brake is rated at 23 Nm, which allows the motor to help secure stationary loads during standstill. A single-turn feedback format stores absolute position within one mechanical revolution, which suits systems that establish a full machine reference during startup. The output uses a shaft with keyway, allowing positive mechanical engagement with pulleys, couplings, or gearboxes. The stator uses winding code 0300, which suits applications that need medium base speed and moderate current demand from a compatible drive. In this motor, the 071 frame and E-length housing provide a compact size with useful thermal capacity for continuous servo operation.
